Japanese prosecutors have questioned Upper House member Anri Kawai and her husband, Lower House member Katsuyuki Kawai, in connection with alleged election law violations.
Three aides to the two lawmakers of the governing Liberal Democratic Party were arrested earlier this month. They are alleged to have paid Anri Kawai's 14 campaign staff members more than the legal limit during her campaign for last year's Upper House election.
NHK has learned that Tokyo prosecutors have questioned a Liberal Democratic Party lawmaker over suspected illegality by a Chinese firm.
Lower House member Tsukasa Akimoto was questioned on a voluntary basis. It is believed that he was asked about his involvement with a Chinese company hoping to enter the fledgling Japanese market for integrated resorts that will include casinos.
