This was an exciting and challenging experience! I recommend this tour for individuals who are adventurous and eager to experience the rawness of Japan. This was a rare and unique experience to have as a foreigner in the Japanese countryside.
We started our tour at the Mura no Eki. I highly recommend buying local produce after the tour (omelettes and tomatoes are famous in town)! We took a relaxing bike ride through the village to get to the cave. Before going in the cave, we changed into ninja suits and tried our hands at throwing ninja stars. Our guide told us the story of the caves which was interesting to learn before entering. The day we went, the cave had been very dry so this meant it was easier to grip the rocks. The guide informed us that on wet days the cave can become quite slippery. In the middle of the cave, we took 5 minutes to meditate in darkness and silence. It was a special moment of tranquillity.
There are several points inside the cave that require climbing ladders, crawling on the ground, and passing through narrow openings. We saw many bats and insects inside as well. The bats were quite alarming to see at first! However the entire time, the bats were sleeping and peaceful. The guide said that in the summer the bats are more likely to fly around.
After the tour, we enjoyed a coffee and some local sweets while chatting with our guide and other members of the community. It was interesting to hear about their stories of the town.
