Motonori Kishi was bemused when he was arrested in October on suspicion of distributing obscene material -- despite the fact that his firm's comic books feature uncensored scenes depicting sexual intercourse.

"I did not understand why only our publication was questioned when other publishers have issued unexpurgated sexual comics," the 54-year-old publishing executive said.

Kishi, president of Tokyo-based Shobunkan Co., has been indicted on charges of selling obscene literature.
