An abandoned Japanese school in Nichitsu, an abandoned mining village in the mountains. To go to this village, we ascended between valleys that were narrower. The last tunnel was a narrow one-way tunnel. After this tunnel, we discovered the first building of a mine and an abandoned town in the mountains. Around 1978 the workers and their families abandoned this village because the mines were not profitable anymore. We spent our time exploring a school and a dancehall.
