Former New Komeito leader Junya Yano said Wednesday that Soka Gakkai, Japan's largest lay Buddhist organization, has been violating his human rights by threatening him and obstructing his freedom of speech.

According to Yano, Soka Gakkai forced him to abandon his activities as a political commentator, published libelous statements about him in the group's Seikyo Shimbun newspaper, and has attempted to force him into selling his house to make a ¥200 million to ¥300 million donation to the group over the last several years.

Yano, who had been a member of Soka Gakkai for more than 50 years, also said he and members of his family have been under surveillance and shadowed by strangers on a daily basis.
