NATSUO KIRINO (桐野夏生), born in 1951 in Kanazawa (Ishikawa Prefecture) was an active and spirited child brought up between her two brothers, one being six years older and the other five years younger than her. Kirino's father, being an architect, took the family to many cities, and Kirino spent her youth in Sendai, Sapporo, and finally settled in Tokyo when she was fourteen, which is where she has been residing since. Kirino showed glimpses of her talent as a writer in her early stages—she was a child with great deal of curiosity, and also a child who could completely immerse herself in her own unique world of imagination.
After completing her law degree, Kirino worked in various fields before becoming a fictional writer; including scheduling and organizing films to be shown in a movie theater, and working as an editor and writer for a magazine publication. She got married to her present husband when she turned twenty-four, and began writing professionally, after giving birth to her daughter, at age thirty. However, it was not until Kirino was forty-one that she made her major debut. Since then, she has written thirteen full-length novels and three volumes of collective short stories, which are highly acclaimed for her intriguingly intelligent plot development and character portrayal, and her unique perspective of Japanese society after the collapse of the economic bubble.
Today, Kirino continues to enthusiastically write in a range of interesting genres. Her smash hit novel OUT (Kodansha, 1997) became the first work to be translated into English and other languages. OUT was also nominated for the 2004 MWA Edgar Allan Poe Award in the Best Novel Category, which made Kirino the first Japanese writer to be nominated for this major literary award. Her other works are now under way to be translated and published around the world.
Kirino's second collection of short stories partly overlaps with 錆びる心 Sabiru kokoro , as it is comprised of texts published between 1996 and 1998, but it also shows her growth as a writer. While having debuted as a crime fiction writer, her earliest short stories in the first collection have already shown she is more interested in exploring her characters than a convoluted mystery or even, sometimes, that much of a plot. Despite that, the stories here still have a strong sense of a mystery - usually involving people's pasts, identities, or desires. In the afterword to the paperback edition, Kirino talks about having enjoyed playing with rocks in the mud as a child, and how she loved to examine them, turn them over and dig in the earth to uncover what's underneath - a game she likens to her own writing process, and uses this metaphor to talk about the short stories in this volume in more detail.
Among these, "Idogawa-san ni tsuite" ("Regarding Mr. Idogawa") leans the closest to a traditional mystery. Here, the protagonist Ayabe is trying to find out whether the sudden death of the titular Mr. Idogawa, a popular, middle aged member of his karate club had been an accident, suicide, or something more sinister - only to find out that Mr. Idogawa was a two-faced creep and a far cry from the idealized figure the karate circle knew. Another story concerning a search for a person is "Yojireta tengoku" ("Twisted Heaven"), where a young Japanese-German stoner Karl, living as a tourist guide in Berlin, is hired by a mysterious Japanese woman. Karl's past is explored in the following story "Kuroi inu" ("Black Dog"), the longer and stronger of the two, where Kirino zooms in on the fraught dynamics of his international, intercultural family and, eventually, on Karl's own sexual abuse as a child.
According to Kirino's afterword, her own favorite in this collection is the first story, "Dead Girl". Inspired by a murder case in a love hotel, it is essentially a single scene taking place in a hotel room, reminiscent of Kirino's later masterpiece Grotesque, but reading it retrospectively also lessens its impact a little. Compared to her first short story collection, Kirino dares to lean more closely into an exploration of questions of identity, such as (repressed) homosexuality in "Rokugatsu no hanayome" ("June Bride") or the Karl stories, or class, economic upheaval and its individual, psychological effects in the titular "Diorama". The final story "Yoru no suna" ("Night Sand") is less than five pages long, but manages to be an evocative and haunting depiction of a woman's passing.
The subtle shifts between 錆びる心 Sabiru kokoro and Diorama signal similar shifts in Kirino's writing in general. After the success of Out, she increasingly pulls away from the framework of a crime novel, exploring other genres and refining the psychogical depth and aspects of her fiction with 柔らかな頬 Yawaraka Na Hoho , which also won her the prestigious Naoki Prize in 1999. The stories collected here therefore present more concise entry points into this phase of Natsuo Kirino's career than her longer novels from the same period.
