One of the great things about Japan is the onsen and the whole Japanese onsen culture. Whenever I am in Japan I always accept any invitations to go to one. My wife went to a new one with her mother while I was in Egypt and she suggested we go there today because it is an especially nice one. It also has a big room with comfortable recliners and individual LCD TVs that you can relax in between baths. Of course, besides the various indoor onsen pools of various temperatures they had several rotemburo (outdoors onsen). They have big digital thermometers next to each one and most were 41-43C, but one was 45C and another was 19C. The air temperature outside was about 6C. I didn't get in the 19C one.
We were there for about 5 hours and bathed and relaxed 3 times in the onsen and also I watched a movie on the movie channel. The Japanese do onsen better than anyplace in the world. Here is the place we went today:
