A Mitsubishi Corp. manager and a Myanmar woman were found stabbed to death in the man's hotel room here, hotel sources said Tuesday.

Shuho Yamanokuchi, the 52-year-old general manager of the company's Yangon office, and the woman, an ethnic Karen, were found in his room Monday at the Renaissance Inya Lake Hotel, the sources said.

The Foreign Ministry confirmed in Tokyo that it had received word that a Japanese man had been found dead at the hotel, where he had been residing.

The hotel sources said that when a company car went to collect Yamanokuchi, the door to his room at the hotel was closed with a notice asking not to be disturbed.

After failing to get a response to their knocks at the door, hotel management opened it and found him and the woman dead.

The woman was said to be married, leading to suspicion that her husband may have been involved in the deaths. Yamanokuchi had sustained more than 20 stab wounds, while four wounds had been inflicted on the woman, according to the sources.

Yamanokuchi, who had lived in Myanmar for about six years, is believed to have been killed before Sunday as he was not seen outside the room after Saturday, the sources said.

He had resided alone at the hotel for about two years, they added.

Two Mitsubishi employees, along with Yamanokuchi's wife, left Japan for Myanmar later Tuesday.
