Academic Societies

  • Science Fiction and Fantasy Writers Club of Japan
  • Mystery Writers of Japan

In Popular Culture

  • Notable for his role in writing Part II of 'Japan Sinks', which drew public attention.

Quotes

  • At first I saw it was written horizontally and thought that alone made it bad... but after reading it, this turned out to be the most engaging piece.
    Source: Yasutaka Tsutsui (from the Kisou Tengai SF New Writer Award selection remarks) (1979)

Trivia

  • His debut work '137 Mobile Brigade' was submitted in horizontal writing and attracted criticism from judges, yet won a prize.
  • His lived and worked experience in Nepal and the Philippines informed settings and material in his fiction.
  • An unofficial fan site hosts detailed publication data and an English translation project; it contains many spoilers.
