Unbreakable: A Japanese American Family in an American Incarceration Camp

by Minoru Tonai, Jolene Gutiérrez, Chris Sasaki (Illustrator)

A powerful, emotional, and ultimately uplifting picture book about the real-life experience of a Japanese American boy incarcerated with his family during World War II

Lying in bed at night, Min thinks about things he’s
his family’s home and business, Puppy, and most of all, Papa.
Min clutches his stone, hoping to see his father again.

Strength comes in the form of the small, smooth stone Min’s father gives him before being led away by FBI agents. In his absence, Min and his family do their best to keep their produce business afloat and earn enough support to get Min’s father released. But after the bombing of Pearl Harbor, they’re forced into an incarceration camp in Colorado.

Imprisoned on the dusty plains and facing both the pain of displacement and the injustice of being incarcerated by his own country, Min must learn to adapt and to find beauty—and strength—where most wouldn’t.

Cowritten by Jolene Gutiérrez, author of Too Much! and Mamiachi & Me, and Minoru (Min) Tonai, an advocate for Japanese American rights, Unbreakable is ultimately an uplifting picture book based on Tonai’s harrowing real-life experiences. Illustrated by acclaimed illustrator Chris Sasaki, this picture book includes extensive back matter such as information on the American incarceration camps and the campaign to release Tonai’s father, a timeline, a bibliography, author and illustrator notes, and questions for further discussion perfect for caregivers and educators to further engage young readers.

This is one of the most powerful and moving picture book biographies I have read so far. It is a story of strength and resilience in the most trying of times, and it gives us a true and honest look at the horrors and injustices that the Japanese community faced through the story of Minoru Tonai and his family. The text is heartfelt and clear, and the illustrations are expressive and really help bring out the tone and meaning of the book. I appreciate the back matter delving more into the history and giving readers the right terminology to discuss this period in American history.

There's a lot that can be learned about the past (and the present) from this story - it is a great addition to every classroom looking to explore more about history.

2026 Reading Alphabet Challenge (Kids' Edition): U

A true story of the real-life Minoru Tonai, who passed away in September 2023 at the age of ninety-four, when he and his family were forcibly relocated to a concentration camp during WWII. It's definitely a harder book to read to small children, but it ends on a hopeful note, and is an important point in history to talk about anyway.

There are a few "questions for further discussion" at the end of the book, but the one I asked my kids was the one that Min rhetorically asks in the story: How can we be sure this never happens again?

It's a really big question, and my youngest definitely didn't have the attention span for it, but my daughter and I were able to have a short talk about the importance of building empathy for people from different cultures/parts of the world.

You can't always read books like these to your kids, but every once and a while I think you should, and when you do, this one is extremely well-done.

This book chronicles the Tonai family's time in a Japanese-American incarceration camp in Colorado during WWII. Beautiful illustrations, and I loved the way Min's father uses the symbolism of a small rock to show strength.

There are several pages of additional content in the back, and I especially liked the paragraphs regarding how we use language to describe the past. The place that Japanese Americans were assigned to live during WWII has been described as relocation centers, internment camps, concentration camps, American concentration camps, confinement centers, and incarceration camps. The authors explain why they chose "incarceration camp" to describe Amache in this story.

This book is simultaneously both heart wrenching (in important ways) and heartwarming/inspiring. The authors worked magic and brought such a needed story to the world in a child appropriate/moving way.

What a sad story! And to think that happened for real. This story follows a Japanese boy who loves to collect rocks until his father is taken away and his family is sent to an incarceration camp, for three years! This is a must to learn about our history. Gorgeous.

A very moving, true story about one Japanese families experience. Definitely a 5 star read! I should add some younger children might find this book heavy and traumatic.

UNBREAKABLE, co-written by Minoru Tonai and Jolene Gutierrez and illustrated by Chris Sasaki, is one of the most moving picture book biographies I’ve read to date. In addition to being well written, this book profoundly moves and wrenches the heart, capturing the resilience and strength of Minoru Tonai and his family during one of the darkest times in American history. Unbreakable shares the true story of Min’s unjust imprisonment at the Amache Incarceration camp during World War II. Chris Sasaki’s breathtaking and beautiful illustrations deepen the emotion, bringing Min’s journey to life on every page. Don’t be surprised to shed a tear while reading this deeply moving and unforgettable story. Through powerful and vivid storytelling along with gorgeous illustrations, readers of all ages can discover the harsh realities Min and his family faced behind the barbed wire—where they endured loss, fear and injustice. This picture book is a must-read and would make a fantastic addition to classrooms and libraries everywhere.

[Tonja Drecker · Rating 5 out of 5]

With potent, yet, gentle illustrations, these pages connect with the reader to bring the unfairness and difficult situation across clearly.

Min loves to collect stones and has found a very nice one on his way home from school, but when he sees an unknown car parked in front of his parents' house, he drops it and hurries to learn what is happening. His father is being accused of being a Japanese spy, and that on the morning after the bombing of Pearl Harbor. Despite lack of evidence, his father is taken away by the police. Neighbors write letters to support the father, but nothing happens. Then, the entire family is told to pack up and move with authorities to a camp and leave everything behind.

First, I really enjoyed the artwork. Each page does a nice job at bringing each scene across in a sympathetic way, which keeps everything centered on Min and his family life as a child. The color hues stay in the browns to fit the atmosphere and give a historic feel the entire way through. The text flows with each scene, sometimes heavier than others, and keeps boredom away while bringing across everything in an understandable and sympathetic manner. At the end of the book, there are several paragraphs about the 'real' Min, changes made to his story, questions for discussion, and more information surrounding the camps and situation. All of this is thought for the adult reader to use in discussions or to share with the listeners.

This book is done with quite a bit of thought and takes great care in making sure the situation is clearly brought across while staying focused on Min and seeing everything through his eyes. It doesn't suddenly twist into 'adultness' but is written for children. And this deserves big kudos on the front. On the other side, I'm not sure it will connect correctly with the younger end of the age group. The situation, war, fears, time period, and so much more involved in this occurrence go beyond this age group, and while they will understand the unfair treatment, the depth behind it will be missing for most. The older end of the age group, who have heard of WWII and, maybe, Pearl Harbor, will be able to digest these pages, especially when combined with the history of that time. So, I would recommend this book more for elementary school readers (ages 6 - 9) and believe it does a great job at bringing the theme across for this age group.
I'm giving this 4.5 stars and rounding up.

I love that you found a story a few parents and many children have never heard of about. Unbreakable is a deeply moving picture‑book biography that brings young readers into one of the most painful chapters of American history — the incarceration of Japanese American families during World War II. I am happy Jolene heard about Minoru “Min” Tonai and knew someone who connected him and her, otherwise this book honoring the resilience, dignity, and love that carried them through unimaginable hardship may not have bee written.

The book follows a young boy named Ben and his family as they are forced from their home and sent to the Amache incarceration camp in Colorado. Gutiérrez writes with clarity and compassion, helping children understand what happened without overwhelming them. She shows the fear and injustice, but also the small moments of hope — the ways families created community, protected one another, and held on to their identity despite the barbed wire around them.

The illustrations created by Chris are rich, expressive, and historically grounded. They capture both the starkness of camp life and the warmth of family bonds. Young readers will feel the emotional weight of the story, but they’ll also see the strength and humanity endured through the characters ‘ faces, both sadness and joy.

This book will open the door for parents and teachers to have essential conversations about civil rights, prejudice, and the consequences of fear‑based decisions. It’s a powerful way to help children understand that history is not just dates and events — it’s families, children, and communities who lived through them. The author’s note and back matter added valuable context for older readers and educators and the stones were a nice addition, too.

Unbreakable is a tender, honest, and necessary story — one that invites reflection, empathy, and a deeper understanding of what it means to stand strong in the face of injustice. Share it with young readers who are asking questions about justice, belonging, and what it means to be American

Unbreakable by Minoru Tomai & Jolene Gutierrez

Thanks to the ALC program by @librofm I had the opportunity to listen to this story. Heartfelt. Unfair. Unthinkable.

Blurb:
MINORU “MIN” TONAI, a young American citizen, and his family must leave everything behind as they are rounded up and unjustly imprisoned following the bombing of Pearl Harbor. From 1942 to 1945, Min, his mother, and his siblings are sent to an incarceration center in Colorado called Amache, surrounded by barbed wire and guarded day and night by armed soldiers. In Unbreakable, the powerful book Min and his friend Jolene Gutiérrez wrote together, Min’s strength is symbolized by the small, smooth stone his father gives him before being led away by FBI agents. 
 
This book captures the harshness of the incarceration camp and the resourcefulness of those who were unjustly imprisoned, as well as the joyful reunion of Min and his papa. By sharing this compelling and inspiring real-life story, it was always Min’s and Jolene’s wish to keep a brutal chapter in history from being forgotten so it will never be repeated. 

My thoughts 💭

I was heartbroken by this story! It was tremendous experience as well as knowing that Min passed away. But he has certainly educated me and now I know what happened to him and so many others! I promise to continue to tell his story. There was no justice for them. He spoke up and he was determined to avoid others to go through what he had been through.

Dive deep with an open heart!

⭐️⭐️⭐️⭐️⭐️/5

Wow. This masterfully written and beautifully illustrated book tells the true heart-breaking story of Minoru Tonai and how, during World War II, his father was arrested by FBI agents and imprisoned while the young boy and his other family members were uprooted and made to live in an incarceration camp – all because they were Japanese. As a Jewish person, I found the descriptions of Min’s experience chillingly similar to the horrors experienced by millions of Jewish families in Europe – good and loyal citizens suddenly torn from their lives, forced to live in inhumane conditions, labeled as dangerous, and stripped of all dignity simply because those in power needed someone to blame. The Authors handle the heavy topic here with such grace. The language is kid-friendly, yet deeply honest. Readers will empathize and connect with Min’s feelings of confusion and fear. I appreciate that the Authors never sugar-coat what happened or the horrible things people and governments are capable of when they feel threatened, and yet somehow in the end the Authors still manage to deliver a message about the power of resilience and offer hope in humanity. Back matter, including Author and Illustrator notes, a timeline, and questions for discussion are included to help inspire important conversations about on the topic. An incredible book that is deserving of all the awards I’m sure will be coming its way.

In UNBREAKABLE: A JAPANESE AMERICAN FAMILY IN AN AMERICAN INCARCERATION CAMP, written by Minoru Tonai and Jolene Gutiérrez and illustrated by Chris Sasaki, Minoru Tonai’s father is questioned in October 1941 about being a Japanese spy. After Pearl Harbor is bombed in December, the FBI takes Min’s father away. Min’s mother tries to run the family business, but customers aren’t buying. Before long, Min and his family are forced to pack up and move to an Assembly Center, where they’re herded into a horse stall to live, fenced in by barbed wire. A few months later, they’re transferred to Granada Relocation Center in Colorado (known as Amache), where they live without a bathroom or running water for two years. Min’s father is finally allowed to join them, then it’s another year after that before they can return home. Succinct, heartfelt text speaks firmly to the many injustices suffered by Min, his family, and all the Japanese Americans who were put into vile camps, and the illustrations, many of which feature characters seeming to look directly at readers, are deeply evocative without being overly sentimental. UNBREAKABLE is powerful, timely, and gracefully done.

[Claudia · Rating 5 out of 5]

The true story of the incarceration of Minoru Tonai and his family during World War II, imprisoned for years after the bombing of Pearl Harbor only because of their Japanese ancestry, is told here in exquisitely simple prose and expressive illustrations. Young Min is devastated when his father is taken away by FBI agents, accused of being an enemy spy, and then when the rest of his family is forced to relocate into a bleak, barren relocation camp, surrounded by barbed wire and patrolled by armed guards, on the desolate plains of eastern Colorado, leaving behind everything from their old life, including his beloved Puppy. But Min remains as strong as the rock he carries with him, a symbol of resilience given to him in farewell by his father. The passion of both co-authors and illustrator to share the crucially important story of this shameful chapter in American history shines forth on every page, as does the message of quiet, stalwart resistance and commitment to make sure an atrocity like this never happens again. A beautiful and inspiring book that richly deserves all the accolades it is receiving.

[The Children's Book Review · Rating 5 out of 5]

Unbreakable is an emotional powerhouse that will leave readers both heartbroken and hopeful. Jolene Gutiérrez, writing alongside the late Japanese American rights advocate Minoru (Min) Tonai, has crafted a deeply moving picture book based on Tonai's real experiences of incarceration during World War II. The story follows young Min, who clings to a smooth stone given to him by his father before FBI agents take him away after Pearl Harbor—a tangible symbol of strength through unimaginable loss. The final paragraph (no spoilers here) delivers perfection.

Chris Sasaki's artwork elevates this already powerful story, providing visual depth to Min's experience. The extensive back matter—including historical context, timelines, and discussion questions—makes this an invaluable resource for educators and caregivers addressing this difficult chapter of American history.

This picture book is essential reading for ALL ages, honoring a painful truth while celebrating the unbreakable spirit of those who endured it. A complete and utter triumph. Loved it!

I'm grateful to have received an advance reader copy of this book from the publisher in exchange for an honest review. I am in awe of the care and beauty taken in both the writing and illustrations of this serious and tender story about an important time in our country's history. I never knew about this as a child and am convinced the more transparent we are about history with children, the better equipped they will be in the future. We are sadly living in a dangerous time where US citizens are being treated less than, again. A book like this not only a moving story, but a wonderful teaching tool. I loved the way the dates were shared across the tops of the pages to help the reader understand the timeframe. Seeing the story unfold through young Min's eyes was both heartbreaking and the perfect way to tell the story. When he had to leave his dog behind, I may have been crying. I loved so much about the story telling with the stone and what it represented. I also loved illustrator, Chris Sasaki's use of white space on the pages giving everything else so much meaning. Highly recommend!

Unbreakable: A Japanese American Family in an American Incarceration Camp, had me almost in tears over what can be done to an innocent family. The story follows Min, a boy who first sees his father taken away for being a spy, then is taken away himself with the rest of his family once the U.S. declares war on Japan after the bombing of Pearl Harbor. As sad and heartbreaking as it is, the authors keep us hopeful with the unbreakable and solid rock collection, which becomes a symbol of strength throughout the story. Surprisingly, we learn in the backmatter that it is true that Min’s father did keep a rock collection and started a rock garden in the incarceration camp as well as one at his home after the war was over (with rocks from the camp). The book has extensive backmatter, from more about Min and his work to bring that period of American history to light to a timeline, questions for further discussions and more. The illustrations by Chris Sasaki are perfect for the story, not relying on cuteness to get the message across, yet pleasant and vibrant.

[Keila Dawson · Rating 5 out of 5]

Unbreakable: A Japanese American Family in an American Incarceration Camp is based on the true story of the Tonai family, told through the point of view of young son, Minoru. This text is a wonderful example of how to teach true history and empathy to young children. And relevant today as we are witnessing the government removing immigrants and descendants of recent immigrants without proof of being disloyal to the country or causing harm to the nation.

“They’ve taken it all, Min thinks. Our father, our freedom and now even our names.”

The authors embed questions throughout the text as a tool so readers can think critically about how the family feels in each situation. The evocative illustrations do what most books aim to, elicit emotion from the reader. Pay attention to what Min and his father look like at the beginning of the story and when they reunite. That illustration made my tears flow. Includes back matter with more information and resources. This book belongs in homes, schools and libraries across the country.

[Carmela Coyle · Rating 5 out of 5]

Unbreakable sits with you for a while after reading. From the start, the almost geometric lines of the gorgeous illustrations by Chris Sasaki evoke the despair and emotion of what must be coming for the main character—a young Min and his family. Poignantly written by Minoru Tonai and Jolene Gutiérrez, Unbreakable tells the true story of Min’s Japanese American family who was swept away into forced incarceration camps “relocation centers” during WWII, like so many other Japanese American friends during that time. These were our neighbors, coworkers, shopkeepers, classmates—all rounded up basically because of fear. But, there is a rock—an ordinary grey rock that Min’s father hands him as he is being taken away. This rock threads the story together in a beautiful and graceful way. The authors have offered readers something sustainable about love and hope and determination in the face of catastrophe. There is plenty of back matter to dig into at the end, which is certain to lead to much discussion. Beautiful through and through.

[Jilanne · Rating 5 out of 5]

This very personal and heartfelt story focuses a lens on a Japanese-American family that lost their family business and was incarcerated during WWII. Imagine being sent to live in a horse stall. This was an example of how the U.S. government treated human beings. Families. How it made a proclamation against an entire group of people. It is a memory we should not forget. Because it resonates with what's happening right now. The father was falsely accused of being a spy, despite evidence to the contrary, and was separated from the family for years, only rejoining them right before they were being released. This story needs to be shared widely. The illustration style in dark tones and sharp lines suits the stark subject matter perfectly. But ultimately, the ending brings light to the darkness, focusing on resilience, strength, beauty and a family's determination to make their lives better after such unjust treatment. Highly recommended.

[Kimberly Shrack · Rating 5 out of 5]

I was lucky enough to receive an ARC of this poignant picture book. This story follows a Japanese-American family as they are unjustly imprisoned in an incarceration camp in the wake of the attack on Pearl Harbor. The story is told through the perspective of Min, a child at the time of the story and a co-author of the book. He has so many questions, most of which go unanswered, something all children can relate to, albeit most times on a much smaller scale. The guided questions at the end make it a great resource for discussing how something like this could happen, and how it could--and currently is--happening again. The book covers a difficult, but important topic in a way that is age-appropriate while still conveying the depth of the injustice from the perspective of a child who lived through it. Highly recommend.

[Vivian Kirkfield · Rating 5 out of 5]

The title, UNBREAKABLE, does not carry over to the state of my heart...which is breaking as I survey the state of our nation at this moment. It breaks for the wrongs done to the subjects of this story...and it breaks for the current situation in our country. But I'm cheering for this glorious book...the art captures the emotions of the characters...and the emotions of the reader. And the beautifully written text connects readers to Min and his family.
This well-researched account gives us important facts and background in very engaging ways...the narrative is never laden down with information to the detriment of the storytelling. And for deeper investigation by teachers, parents, and young readers, the back matter provides clear explanations and further resources.
I highly recommend this for ALL school libraries and home bookshelves.

UNBREAKABLE: A Japanese Family in an American Incarceration Camp by Minoru Tonai and Jolene Gutiérrez is both heart‑wrenching and deeply inspiring. It’s a story that absolutely needed to be told, and Tonai and Gutiérrez share it with power, clarity, and respect—making it accessible and meaningful for readers of all ages.

The book recounts Minoru Tonai’s true experience of unjust imprisonment at the Amache Incarceration Camp during World War II. Chris Sasaki’s illustrations are vivid, emotional, and beautifully detailed, perfectly complementing the authors’ compelling storytelling.

The extensive back matter adds valuable context and offers rich opportunities for important conversations. Moving and unforgettable, this picture book is a must‑read and a vital addition to libraries, classrooms, and homes. 100% recommended.

[Melissa Stoller · Rating 5 out of 5]

This beautiful and poignant story is told from the viewpoint of Min, who is forced to leave his home in California during World War II and “relocate” to an incarceration camp for Japanese-American people. The injustices faced are described with care and emotion - especially touching was when Min had to leave behind his puppy. Through it all, he kept a stone his father presented to him before his father was taken away. Along with other stones shown later in the story, this one symbolizes strength, fortitude, and eventually resilience. The book ends on a hopeful note, and invites readers to understand this dark chapter in American history so that it may never be repeated with any group of people. Back matter including a timeline, author and illustrator notes, and questions for discussion add extra enrichment. A must read for homes, schools, and libraries.

[Shoshanna · Rating 5 out of 5]

An extremely important picture book! Min is a child living in California with his family leading up to the United States involvment in World War II, and ultimately, his family is sent to the Amache relocation / internment / incarceration / concentration center in the deserts of Colorado. The artist but also very very clear illustrations as well as the straightforward narrative, from a child's perspective (coupled with questions from his inner thoughts), really help illustrate to kids and grownups what the experience was of Japanese families living in the United States at the time. Children who may have visual knowledge of NAZI concentration / death camps will see parallels, as well as those drawn to the current ICE detention centers. History comes alive, even though that history is horrific.

I hope this book wins all the awards. A chilling yet tender story of an American family unjustly incarcerated in 1942 by our government, along with 120,000 other people, for being of Japanese descent. Beautifully written by Minoru Tonai and Jolene Gutiérrez, the lyrical language flows with fact and feeling through journeys of all sorts. The stunning illustrations by Chris Sasaki capture the bleakness of their stolen lives but also the unbreakability of their hope. I especially loved the before/after scenes and the poses repeated to great effect. The back matter is also A+, with a timeline of events, a note on which details were fictionalized, and a discussion of how our government used euphemisms ("relocation centers" instead of the more accurate "incarceration camps") to hide the truth. Thank you for this book. My condolences to Jolene and Minoru's family on his passing in 2023.

[Carren · Rating 5 out of 5]

There are some pieces of history that is difficult to understand, but the authors do a great job of making a big, hard chapter in American history approachable and relatable. They describe in clear, solid ways how Japanese Americans (who are Americans themselves) felt when their loved ones were taken away, when they were asked to live in stalls, and then barracks, from the straw mattresses to the sand that blows with the wind into the cracks in their makeshift home at Amache.

This book deals with the Japanese American incarceration and provides a glimpse of what it was like to live through those harrowing moments so their lessons of strength and resilience is something won't be so easily forgotten.

[Emily Barth · Rating 5 out of 5]

I got to hold and read this stunningly gorgeous book at a conference and I knew it was going to be life-changing from the start. What a compelling, important, and achingly-relevant book this is! Beautifully brought to life by two amazing authors and with incredibly vivid illustrations, this true, historical story is more important than ever now. Readers will relate to Min and see just how close our history is, and how it is all-too easy for history to repeat if we do not take the time to learn from it. This is also a wonderful example of how picture books can--and should!-- be used in classrooms from elementary through high school (and beyond) to succinctly convey history and its emotional impacts.

[Charlotte Sherman · Rating 5 out of 5]

With quiet, elegant prose and evocative illustrations, Unbreakable illuminates the heartbreak of Japanese American families during the travesty of the WWII internment camps in America. Written in clear language that is easy for young readers to absorb, this story tells the truth without sugarcoating the horrors of incarceration and family separation. In the end though, it highlights the resilience of the human spirit even in the worst circumstances and the triumph of strong family bonds, and love, that no barbed wire can break. Backmatter provides additional information. A timely story as we learn of the horrors our neighbors face today in hellholes called Alligator Alcatraz and Camp East Montana, among others. Can't recommend this book enough. Brava!

[Korena Howley · Rating 5 out of 5]

Co-written by Minoru Tonai and Jolene Gutierrez, Unbreakable tells the story of Minoru’s incarceration, along with his family, in California and Colorado during World War II. From the first signs of distrust against Americans of Japanese descent until their eventual release, Min must hold on to the hope that he’ll be reunited with his father and that his family will be allowed to return home, even as the years pass in their grim surroundings.

Beautifully told and illustrated, it’s a moving reminder that behind every unjust incarceration, be it then or now, is a person or family with a story to tell—and the hope that someone will listen.

Back matter, including notes from the author and illustrator, offers more to reflect on and discuss.
