A husband and wife have died after being trapped in a private sauna room that caught fire in Japan on Monday. Tokyo police are investigating whether a faulty doorknob trapped the couple inside the room at Sauna Tiger, in the city's Akasaka district, local media has reported. Investigators also found that the facility's emergency alarm system was switched off, and allegedly had been for two years. We offer our deepest condolences... and our heartfelt sympathies for the deep grief and pain that cannot be expressed in words, Sauna Tiger said in a statement on its website. The victims have been named by local media as Yoko Matsuda, a 37-year-old nail artist, and her husband Masanari, 36, who ran a beauty salon.
