Tokyo, Jun 6 (IANS): A Japanese court on Thursday sentenced a 44-year-old YouTube content creator to two years in prison for assaulting and confining his wife at their home after he found she had been posting defamatory comments on videos he had uploaded.

The Oita District Court ruled that Ryoma Katori seriously injured his wife in March by punching and kicking her in the face while she was confined in their apartment in the city of Oita with her wrists and ankles bound with adhesive tape, reports Kyodo News Agency.

While handing down the sentence, Judge Sadahiro Ariga said the defendant's act "should be strongly criticized as he committed the crime after losing his temper".

According to a defence lawyer, Katori had been trying for more than six months to find out who had been posting negative comments, including "stupid" and "bald", on his online videos when in March he realized that it was his wife as she had requested a friend to post similar comments.
