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.

Hot Springs

Dake Onsen

Dake Onsen is one of Japan's few naturally acidic hot spring sources. The onsen source is located some 8 kilometers away from Dake Onsen town, meaning the hot spring water must be pulled from the source, travelling for around 40 minutes before it reaches the town. During this journey, the hot water becomes softer, making it gentle on the skin. Since the Dake Onsen's hot spring waters are acidic, it is recommended that visitors rinse in the shower after bathing in the town's onsen. This onsen town is also a popular spot for cherry blossom viewing. The cherry blossom tunnel at Sakura Hill in Dake Onsen – an onsen town located on the periphery of Mt. Adatara – comes into full bloom in mid-April. Visitors are greeted with fantastic views of cherry blossom against a backdrop of Mt Adatara still sprinkled white with the remainder of last winter’s snow.

Mt. Adatara

Mt. Adatara is actually made up of multiple active volcanoes that form a broad mountain. It last erupted in 1996. Poems in the book Chieko-sho by Kotaro Takamura (1883-1956) helped make the mountain famous.The summit of Mt. Adatara stands at an altitude of 1700 m, stretching about 9 kilometers in a north-to-south direction. Views of Mt. Adatara are lovely in and of themselves, but the views that visitors have of the surrounding area once they reach the summit are breathtaking. Chosen as one of Japan’s top 100 mountains, as well as one of the top 100 mountains for flowers, a view spot at an altitude of 1300 m can be accessed by gondola lift. This means that it is relatively easy to climb even for beginners.On summer evenings, a light-up event inspired by the Milky Way and the flowers of Mt. Adatara is held, gracing those scaling the mountain by a gondola lift with a spectacular view. In autumn, visitors are afforded a stunning view of autumn leaves making it a popular place for scenic momiji-gari (autumn leaf viewing).Kurogane-goya Mountain Lodge (temporarily closed as of August 2023) is a rest stop for visitors (it serves as lodging for those on long hikes). Stay here overnight to sample the lodge's famous curry, which is reserved for overnight guests only. The lodge’s public hot spring facility uses naturally-sourced, cloudy hot spring water.
