One week after two customers died in a fire in a private room at a luxury sauna facility in Tokyo’s Akasaka district, police are investigating the facility’s operator for possible professional negligence resulting in death.

According to investigative sources, the Metropolitan Police Department has so far found evidence suggesting that the two customers tried desperately to escape the sauna unit in the private room, as the sauna’s door was broken and the emergency system did not work.

The fire occurred around noon on Dec. 15, and the victims — Masanari Matsuda, a 36-year-old beauty salon owner, and his wife, Yoko Matsuda, a 37-year-old nail technician — were found lying near the door inside the sauna. They were rushed to hospital but pronounced dead.
