Taiyo Fujii was born in Amami Oshima Island-that is, between Kyushu and Okinawa. He worked for stage design, desktop publishing, exhibition graphic design, and software development. In 2012, Fujii self-published Gene Mapper serially in a digital format of his own design, and was Amazon.co.jp's number one Kindle bestseller of the year. The novel was revised and republished in both print and digital as Gene Mapper - full build- by Hayakawa Publishing in 2013, and was nominated for Japan SF Award and Seiun Award. His other works include Underground Market and Orbital Cloud.
