Police said Friday they have arrested a man in Iwate for allegedly killing his wife with a hammer.
The man, who has been named as 34-year-old Junichi Kumagai from Yahaba, called police after he allegedly hit his 30-year-old wife, Kaori Kumagai, on the head with a 20-cm-long hammer, just after noon on Thursday, NTV reported.
Police say she was rushed to hospital for treatment and Kumagai was initially arrested on a charge of attempted murder. Kaori was treated at the hospital for around four hours before succumbing to her injuries. Police said Friday the charge has been changed to murder.
Neighbors of the couple told reporters that they believed Junichi Kumagai to be a violent man, NTV reported. Police say that Kaori Kumagai had visited police twice before to seek help following cases of domestic violence.
Kumagai was quoted by police as saying that he blacked out at the time of the attack.© Japan Today
