A lawmaker is under pressure to step down following a media report that he allegedly dined out with an 18-year-old woman, urged her to drink alcoholic beverages and gave her money. The drinking age in Japan is 20.
Lower House member Yoshikawa Takeru resigned from the main ruling Liberal Democratic Party last week, saying he had caused trouble.
Prime Minister Kishida Fumio on Wednesday stated it would be extremely regrettable if the report of Yoshikawa's conduct was true.
He said lawmakers should never shirk from providing an explanation to the public, regardless of their party affiliation.
Kishida added that Yoshikawa needs to consider resigning from the Diet if he cannot account for his behavior.
