The Tokyo High Court on Tuesday upheld a lower court-imposed life prison term for a man convicted of murdering the wife of a Yamaichi Securities Co. legal adviser in 1997.

Presiding Judge Yoshimasa Kawabe upheld the sentence for 67-year-old Hisashi Nishida for the stabbing death of Manae Okamura, 63, wife of 72-year-old lawyer Isao Okamura, a former vice chairman of the Japan Federation of Bar Associations.

Nishida was sentenced to life by the Tokyo District Court in September 1999. Prosecutors had appealed to the high court, seeking capital punishment, and Nishida also appealed, seeking a lighter sentence.
