When you take a Japanese-style bath, you sit down inside the bathtub with your knees bent. In a Western-style bath, you usually lie down with your legs flat. I read somebody once said that Japanese way was the fetus style and the Western way was the coffin style. I admire his expressiveness!
I have been to Hanoi, Bangkok, Hong Kong and Pusan in Asia. I stayed in hotels and all of them had Western-style bathtubs. Are there any other countries where they use the fetus or another style of bathtub?
