#龍泉洞

Located at 1-1 Kaminari, Iwaizumi, Iwaizumi-cho, Shimohei-gun, Iwate Prefecture. In summer, it's cooler on the mountain or in the cave. It's one of Japan's three largest limestone caves.

There are stunning blue underground lakes scattered throughout.

There are stairs along the way, totaling 270 steps.

I turned back here. I couldn't climb.
