A great introduction to feminism for teenagers (and language learners at the upper-intermediate level or above). Ueno uses a Q&A format, apparently drawing from a corpus of questions about feminism and related topics collected from young Japanese girls and women. The questions are logically arranged and build upon one another.
Teenagers and language learners alike will encounter new words (kanji, at least) and phrases, but furigana and/or explanations are provided. Easy to read and understand.
Ueno is engaging and frank. At the same time, she has a particular worldview (a dated one, I'd say) and it's clear she's speaking to a certain audience (or entertains certain assumptions about her audience). While she brings up gay relationships, class, and disability, she otherwise writes from a cisheteronormative perspective, where foreigners and people beyond the binary don't exist. Part of this can be chalked up to her generation (which she admits to at points, requesting that her audience create their own future on their own terms) and the current state of affairs in Japan. She's called a radical, but she's only radical within the Japanese context. As the title suggests, she's writing to young Japanese women, exclusively. But I'm left wondering why, especially because young men need to be part of the equation, as Ueno herself asserts throughout the text.
The book ends with her speech to the incoming 2020 class at Todai. A nice addition that summarizes the main points from the rest of the text.
Overall, I'd recommend it to those looking for a feminism 101 text by an erudite pioneer in Japanese gender equality scholarship and activism.
