Yasuhiko Nishizawa was born in 1960 in Akashi, Japan. He studied Creative Writing in the United States, before returning to Japan and beginning to write murder mysteries while working as a university assistant and high school lecturer.
Cool set-up for a special setting mystery, and Nishizawa definitely uses it for the best. My one quibble with it would be that the motive is kinda ehh, but I can live with that.
