A Nepali man who was imprisoned in Japan for 15 years for a murder he didn't commit said Monday he is considering filing a suit for damages against the government for his wrongful imprisonment and mistreatment.

Govinda Prasad Mainali, 46, was wrongly convicted of murdering a Japanese woman, but only freed and cleared of the murder charge years later.

He told Kyodo News in an exclusive interview at his three-story Katmandu residence that he will wait for the result of a similar suit filed by Shoji Sakurai, a wrongly convicted Japanese man, to decide.
