Otaki Limestone Cave 大滝鍾乳洞

South of Gujo Hachiman town center is the largest network of caves in the region, the most accessible is Otaki Limestone Cave.

You can reach the cave by taxi.

There are no direct public transport links to the cave. From Gujo Hachiman Station, a taxi takes around 20 minutes.

Otaki Limestone Cave is well lit, although there is a lot of water around so the rocks can get slippery. It can also get cold inside, so dress accordingly. It takes about 30 minutes to walk the 700-meter stretch that is open to the public. When you reach the 30-meter high waterfall, you're nearly at the end.

Many of the stalactites have grown into recognizable shapes and been given names such as “Decorated Cake” or the “Leaning Tower of Pisa.”
