The wife of one of the radicals who hijacked a Japan Airlines plane to North Korea in 1970 appealed Wednesday the suspended sentence she received from the Tokyo District Court for violating the Passport Law.
Earlier this month, Tamiko Uomoto, 51, was sentenced to 18 months in prison, suspended for four years, for failing to obey a 1988 government order to surrender her passport.
The court said the order was legal because Uomoto could have been engaged in terrorism or other activities that might disrupt public order.
Her lawyers called the ruling unacceptable, saying it was not backed by evidence.
Uomoto returned her passport in December 2003. Tokyo police arrested her in February 2004 upon her return to Japan.
On Tuesday, another wife of the hijackers, Kyoko Tanaka, 48, was arrested on the same charge.
