Azuchi Castle Ruins. This was the castle of famous feudal warlord Nobunaga Oda. There are only stone walls and stairs were left, but I guess it is what is called decadentism, the place has a nice atmosphere. From the tower ruin, you can overlook the townscape and the lakescape.

I entered Kawachi Wind Cave. The inside of the cave is very cool regardless of summer! I thought there is likely Blue Grotto, Italy, but underground lake was keep out area. Well, it was nice to feel the power of nature even just in the public open area.
