Two men were found dead Tuesday in a sauna at a business hotel in Wakayama City.
According to police, the two men were found, one lying on top of the other, at about 6 a.m. at City Inn Wakayama. TV Asahi quoted hotel staff as saying that the men, both in their 50s, were drunk when they went into the sauna at around 2 a.m. An ambulance was called but the two men were already dead by the time it arrived, police said.
Police said there were no signs of external injury on the bodies and plan to conduct an autopsy to determine the cause of death.
Steam in the sauna was electrically generated. The temperature inside the room was 52 degrees Celsius when the bodies were discovered. Falling asleep inside a sauna can cause blood circulatory problems, health officials say. Going into a sauna while drunk can also cause the body to become dehydrated.
Many hotels post warnings outside saunas, urging people not to go in if they are drunk.
