* I've been rating/reviewing only books that are available in English, but I'm changing this personal rule to see if anything happens. There are contemporary Japanese novels that are worth reading (Haruki Murakami is not the only one, you know), and if enough people show interests, they might get translated. *
Natsuki Ikezawa (1945- ) is a novelist, translator, and literary critic. I'm not impressed with his critics and short stories, but this novel Shizukana Daichi (Quiet Earth or Quiet Land), reads like a timeless classic.
Many people, including the Japanese, believe Japan is a "homogeneous" society with only one ethnicity, but that's not true. Okinawa was once an independent kingdom, and Hokkaido was a free land of hunter-gatherer Ainu, much like what Central Asia was before China invaded. In Hokkaido's case, the mainland Japanese took it from the Ainu and started mass settlement in the late 19th century. This historical fiction is unique because the protagonist is one of those newly-settling Japanese but he attempts to work with the Ainu.
Due to this viewpoint, many Japanese readers felt criticized. (In other words, his marketing strategy was not well-planned.) I think non-Japanese might be better positioned to appreciate its tone of quiet passion and superb storytelling.
