In the Edo period (1603-1868), many artists, such as Hokusai Katsushika or Kuniyoshi Utagawa, created their works of featuring Yokai inspired by folklore or their own ideas. Yokai have attracted the artists and have been a common theme in art works until these days because of their unique forms and their mysterious behaviors. This would be an attractive book for Yokai beginners and established Yokai fans, and would be also a valuable source for designers and illustrators. Most of the items that will be featured in the book come from personal collections by Koichi Yumoto, who has the largest Yokai collection in Japan. He comments on the history of Yokai and explains about the items in the book.
