A 19-year-old Thai woman has died in a Tokyo hospital after being severely assaulted on Tuesday, according to the Foreign Ministry.
Spokeswoman Busadee Santipitaks said on Thursday the Thai embassy in Tokyo had reported the Thai tourist was pronounced dead at a hospital in the Japanese capital. Police had yet to officially report on the cause of death.
The Department of Consular Affairs had informed the victim's mother, she said.
Japanese media reported that a naked woman was found unconscious, severely beaten about her face and body, in her room on the fifth floor of a hotel near the Jr Uguisudani train station in Tokyo about 8.30pm on Tuesday.
A Japanese man in his 20s was also found dead, with a broken skull, on a footpath in the street outside the hotel.
Hotel staff said that a short time earlier they heard sounds of a loud dispute coming from the couple's room, and the woman screamed.
