"We want to conduct a necessary study based on such factors as the recent social situation," Hiraguchi said at a press conference.
Currently, the purchase of prostitution is not punishable under the prostitution prevention law.
Prime Minister Sanae Takaichi earlier this week instructed the justice minister to conduct a study on regulations on prostitution and the purchasing of prostitution.
Hiraguchi said that he takes Takaichi's instruction seriously.
