In the article, which hit newsstands on Thursday, Takaya Muto, 36, who last week resigned from the ruling Liberal Democratic Party for alleged involvement in a financial scandal, met the 19-year-old prostitute on approximately 20 occasions since November of last year. Muto paid the prostitute 20,000 yen per session.
In at least one case, the pair met at a residence for Lower House members.
Bunshun reprinted a message exchange between Muto and the prostitute in which the former lawmaker is seen making specific sexual demands.
When contacted by the magazine, Muto denied the allegations.
The LDP accepted a letter of resignation from Muto last week after the publication of a previous article in Bunshun in which the former lawmaker is alleged to have cheated investors in the purchase of unlisted stocks.
According to the article, a secretary of Muto misappropriated eight million yen of a total of 41 million yen collected from 23 investors. As well, Muto withheld about seven million yen that was to be returned to six investors.
Muto has also denied those claims.
On July 30, Muto initially caused a stir on Twitter when he described students protesting a pair of security reform bills as “selfish.”
