BANGKOK (Kyodo) -- A Japanese man in his 30s who was taken to a hospital after being injured in a recent fire at a hotel in Bangkok has died, the Japanese Embassy in Thailand said Wednesday.

The man was staying at the Ember Hotel near the popular tourism spot Khaosan Road when the fire broke out on the night of Dec. 29, Thai authorities said, adding he had been unconscious since inhaling smoke in the incident.

A Japanese woman in her 30s who stayed in the same room with him has also been treated at a hospital after she inhaled smoke, they said.

The fire, which started in a room on the fifth floor of the six-story building, left three others dead -- a Brazilian woman, a Ukrainian man and an American man -- and several injured, according to local media reports.

The Bangkok Post said more than 30 people were rescued from the rooftop by firefighters.
