A former lawyer was sentenced to four years in prison Monday for defrauding a Tokyo company of some 400 million yen in 1991.

The sentence was imposed on Nobukata Naritomi, 70, a former lawyer with the First Tokyo Lawyers' Association, by the Tokyo District Court. Prosecutors had demanded a five-year prison term for the defendant.

According to the court, Naritomi approached a Tokyo company president in 1990 and talked him into getting his company to obtain the exclusive sales rights in Japan of garbage disposal machines, developed by a company with its headquarters in Central America. Naritomi told him he would serve as an intermediary for the deal.
