Kazuyo Katsuma

Kazuyo Katsuma reshaped an entire shelf of Japanese bookstores in the late 2000s. Born in Katsushika, Tokyo in 1968 and a Waseda University graduate, she worked as an accountant before becoming a businesswoman, author and blogger. Her books have sold in enormous numbers, and they are mostly about self-management, work-life balance, gender equality and the mechanics of thinking faster and producing more. For a period she was a genuine social phenomenon in Japan, with her readers acquiring a nickname of their own. The optimization philosophy has never been universally loved. Critics argue that framing life as a productivity problem puts the burden squarely on the individual and ignores the structures around them, and that is a fair argument. But I think a great many Japanese office workers, particularly women, looked at how they actually spent their hours for the first time because of her writing. What I respect most is the consistency: she still runs her own site and social accounts, writing in her own voice.
