Irimizu Limestone Cave (Irimizu Shonyudo)

Irimizu Limestone Cave (Irimizu Shonyudo)

Visitors looking for a cool and adventurous experience should consider visiting the Irimizu Limestone Cave (入水鍾乳洞) in Tamura City.

Perhaps less known than the nearby Abukuma Cave, the Irimizu Limestone Cave offers visitors the opportunity to venture into its depths—the narrow cave is 900 m in total and is divided into three courses (A, B and C), each more extreme than the previous one.

Visitors should bring adequate clothing and shoes, as the inside of the cave is wet and slippery with irregular rocky ground and gushing streams.

Course A is the least extreme, and the way into the cave is lit, although there are puddles and wet spots, and you will need to duck in some places since there are short and narrow spots. Course A is 150 m long and takes approx. 30 minutes to complete.

Courses B and C go through an area of the cave where there is less conditioning. Visitors have to walk while having water up to their knees and go through slippery and narrow gaps by candlelight or flashlight.

Course B is 450 m and takes about 60 minutes to complete, while course C is 300 m and takes about 90 m to complete.

Visitors hoping to undertake course C, the most difficult of the three, have to make a reservation before their visit, as the course can only be completed alongside an experienced guide. *Course C is not available and is not taking reservations as of May 2023.

The temperature inside the cave is typically between 10 and 15 degrees regardless of the season.

There are candles, rubber shoes, flashlights and other items available for renting at the entrance.

Prices are as of March 2023.

The cave has been designated as a National Natural Treasure, and it’s easy to see why. You’re bound to become a geology enthusiast after experiencing the charms of the cave.
