Mari Kotani

In 1997, Media Works published a reference book, Alternative Culture, which contained an article describing Kotani's book, Evangelion as the Immaculate Virgin, and depicted Mari Kotani's name as a pseudonym for her husband Takayuki Tatsumi, a professor of English at Keio University. When her complaints were ignored, she sued the author of the entry (Hiroo Yamagata), the publisher and Shufu-no-Tomo-sha, the distributor of the book, for what she termed "textual harassment." The lawsuit was broadly supported by Japanese writers. The Japan PEN Club established a Women Writer's Committee, with feminist critic Kazuko Saegusa as chair, and Kotani as sub-chair. During this period, Kotani and Maki Honda's translation of Joanna Russ' How to Suppress Women's Writing received by major feminist critics in Japan including Chizuko Ueno, Fukuko Kobayashi, Yuko Matsumoto, and Kazuko Takemura. In 2001 the defendants were ordered to pay Kotani 3,300,000 yen (roughly $27,500), and to publish an apology on the top page of their respective website.[3]

Kotani was not the first cosplayer in Japan but she is the earliest documented instance of cosplay at a fan event in that country. She attended a costume party at the 17th Nihon SF Taikai (also known as "Ashinocon") science fiction convention in 1978 wearing a costume based on the cover art for Edgar Rice Burroughs' novel A Fighting Man of Mars.[4][5] This costume has sometimes been misreported as a Triton costume (from the manga Triton of the Sea) due to its visual similarity and because Kotani was known at the time as a member of the TRITON fan club.[4] She was one of about the twenty people at the event wearing a costume; the others were either members of the same Triton of the Sea fan club or of Kansai Entertainers (西芸人人, Kansai Geinin), the antecedent of the Gainax anime studio.[4] Despite being a costume party, most attendees wore ordinary clothing.[4]

In 2003, she established the annual Kotani Cup "for celebrating the best cos-players at Japanese National SF Convention."[2]
