The Supreme Court asked the Diet on Monday to dismiss a Tokyo High Court judge who was arrested May 19 on suspicion of paying a 14-year-old girl to have sex with him in January, court officials said.
The top court decided Yasuhiro Muraki, 43, should be impeached in the Diet because the allegations constitute the violation of a law against child prostitution.
Muraki has reportedly admitted to the charge and indicated he wants to resign, though he has yet to be indicted.
The Diet's Judge Indictment Committee will examine the case and decide whether to impeach Muraki in the Judge Impeachment Court, the officials said.
If Muraki is impeached and fired in the special tribunal, he would be the fifth judge to be dismissed since 1981.
The Tokyo High Court concluded the allegations against Muraki were justified and his act deserves impeachment, the officials said. The Supreme Court made the decision based on a report from the high court.
Several officials from Tokyo's Edogawa Ward Office made similar requests to the Diet as they were concerned about the case.
According to police, Muraki, from Nakano Ward, paid the girl -- a second year junior high school student at the time -- 20,000 yen to have sex with him at a hotel in Kawasaki.
Police said Muraki had been introduced to the girl by her classmate, whom he had met through a mobile phone Web site designed to facilitate such encounters.
