三ツ合鍾乳洞 (Mitsugo shonyudo) is the smallest of three show caves in the area and is only 120 m long. Nevertheless it has three different levels, which means lots of stairs. Because of shrinking visitor numbers in the last 20 year the cave was sometimes closed and prebooking recommend. It was still open in 2017 but it seems the cave is now finally closed, it is not listed any more on the website of the town.
