露天風呂(ROTEMBURO) - (n.) The Onsen taken to another level of perfection - outside bathing.
NB. Due to the suicidal nature of mixing digital photography and hot water, I've been forced to turn to the generosity of the internet for these photos...
Great Baths of Japan - Sakurajima - Furusato Onsen

On the far southern tip of what could be called mainland Japan, Sakurajima sits, smoking belligerently. A large and very active volcano, it sporadically sends vast clouds of smoke and ash rolling up into the atmosphere. It used to be an island, but in 1914 a great eruption spilled enough lava to connect it to Kyushu.
As the lumpen black rocks boulder down to the sea, geothermally heated water bubbles up to the surface. And right between this great volcano and the Pacific Ocean, this water feeds a very unusual onsen.

As I lay back in the steaming hot waters, English places of worship seemed a very long way away. How could I even compare the hard, drafty pews of ascetic Protestantism to this balmy experience. Of course, Japanese religion certainly can do ascetic - think Zen monks up at dawn to meditate, with a Master hitting them with sticks whenever they showed signs of drooping, or a Shugendo Monk (allied to Shinto) meditating for hours under a freezing waterfall. But Shinto seems, on the whole, to be rather more keen on appreciating the good things of life.
With your back to the shrine, the Pacific Ocean spreads out before you. When I was there, the rain was heavy, the wind cold, and the waves strong. They crashed onto rough rocks with a huge weight, rendering the 'no swimming' signs rather unnecessary. I took turns between immersing myself in the hot waters until they proved unbearable, and then standing out on the rocks and feeling the heat drain from my skin in seconds. Then back in the water for another 5minute soak. Repeat until beaten by the elements into a heady state of relaxation, as you watch the seabirds fly overhead and listen to the waves barely 5m away.
