Yumeno Kyūsaku (夢野 久作, 4 January 1889 – 11 March 1936) was the pen name of Sugiyama Yasumichi (杉山 泰道), an early Shōwa period Japanese author, Zen priest, post office director and sub-lieutenant.

After graduating from Shuyukan he attended the Literature Department at Keio University, but dropped out[1] on orders from his father, and returned home to take care of the family farm.

By this time, he had developed a strong interest in the traditional Japanese drama form of Noh, with its genre of ghost stories and supernatural events.

He found employment as a freelance reporter for the Kyushu Nippō newspaper (which later became the Nishinippon Shimbun), while writing works of fiction on the side.

His subsequent works include Binzume jigoku (Hell in the Bottles, 1928), Kori no hate (End of the Ice, 1933), and his most significant novel Dogura Magura (Dogra Magra, 1935), which is considered a precursor of modern Japanese science fiction[2] and was adapted for a 1988 movie directed by Toshio Matsumoto and starring Shijaku Katsura II, Hideo Murota, and Yōji Matsuda.
