I like
ONSEN very much, for me it is a place where i can put myself aside from all daily thoughts (escaping from reality in other words :))
When I go to onsen I enjoy sauna and mizuburo (water bath) and endless talk with people, seeing the moon shining just above. It's a gorgeous time, believe me if you never tried onsen you should experience once in life time.
My favorite onsen is called '
Tonbo no Yu', it's got clean, good quality onsen with fine environment. The picture below is the way to the changing room, to the right is for female and the other side is for men.
If you could see a little stream at center, that's where people cool down their feet on the way back to the main entrance.
Time flows really slowly here - I like it.
