Irimizu Cave

[Tamura City, Fukushima Prefecture] Irimizu Cave is a dungeon you have to crawl through on all fours! It's full of charm that you won't find in Abukuma Cave!

Fukushima Prefecture is home to the nationally famousAbukumaCave. This time,the Abukuma Cave Systemanother cave that formsIrimizu Cave,we will introduce


The difference between Irimizu Cave and Abukuma Cave

Like Abukuma Cave, Irimizu Cave is also open to the public as a tourist cave. However, Abukuma Cave is decorated with electric lights and has been designed to be easy to walk through, making it very tourist-friendly

On the other hand,Irizumi Limestone Cave is in a completely natural state. There are no fancy lights or anything like that; only a single faintly glowing rope, like the ones you'd find at a construction site, runs through it.

If you don't bring any light, it will be pitch black.The ground is rough and uneven, the water comes up to your knees, and water drips from above. Once you go in, you'll be completely soaked.

Irimizu Cave offers an adventure that is truly like conquering a dungeon, with a high level of awareness


Preparations required for entering the cave

As mentioned above, you will get wet when you enter the cave. Therefore, you need to wear clothes that you don't mind getting wet. Of course, you should also bring a change of clothes

Irimizu Cave

Because it is a limestone cave, it is generally wet and slippery everywhere, so you need to wear shoes that are ok to get wet and have smooth soles that won't slip

Inside the cave, the ceiling is extremely low, and there are points where even children have to crawl on all fours to get through. It's pitch black without any light, soa headlampwill be very useful.

Having these preparations will give you peace of mind, buteven if you go empty-handed, you can rent sandals to use as shoes and candles to use as lights at the reception.


Three courses of Irimizu Cave

Irimizu Cave

There are three courses available at Irimizu Cave. Although the courses are divided, they do not necessarily follow different routes

  • Course AThose onCourse Bshould go to the entrance of
  • Course BThose takingCourse C.should make a U-turn at the entrance to
  • Course Cinvolvescourses A and B, then entering course C, going all the way to the end, and returning.

"how far you want to go, the course is divided based on

Course A

Course A (550 yen for adults, 450 yen for elementary and junior high school students) is easy to go. You won't get too wet, and it's not too dark. The path is relatively wide, and there are only a few welcome rugged slopes to descend

You can easily go there without all the preparations mentioned above. The ground is paved with rubber sheets and iron plates, so it's easy to walk on

Course B

From Course B (700 yen for adults, 500 yen for elementary and junior high school students), the adventure begins. The temperature inside the cave is a chilly 14 degrees all year round, and the water is piercingly cold, reaching up to your calves (or knees on some days)

If you choose course B or higher, you will receive instructions at the reception desk.The coldness of the wateris among them. It's more of advice than a warning, saying, "It's cold at first, but you'll get used to it after a while."

It's true that at first it's so cold that it makes your head numb. Women and children may scream and cry. But eventually, you start to lose sense of numbness, and it becomes clear that your head is really numb

Many people are discouraged by the initial coldness and darkness inside the cave and turn back, but once you get over that, you will gradually get used to it

Candles double the thrill

Light is a necessity from Course B onwards. If you are not prepared, you will have to rely on the candles provided at the reception. However, since they are candles, there is a risk that they may go out if water drips on them from above

If it disappears, you will suddenly find yourself in complete darkness and may panic because you will not know which way to go. Furthermore, since it is a one-way road, there will of course be people going there and coming back

The road is extremely narrow, so when passing someone, you worry about getting the candle on their clothes. If the other person is holding a candle, you get nervous too

Candles create a great atmosphere, but they do come with the risks mentioned above. If you're going for the first time or don't mind a less adventurous trip, we recommend bringing a headlamp or a clip light (sold at 100 yen shops) that will allow you to keep your arms and legs free

Insects and bats bring different fears

Inside the cave, you can find disgusting insects with lots of legs, such as millipedes, crab bugs, cockroaches, and springtails. Bats also live here

If you are intolerant of insects or bats, you should be prepared not to panic if you see one or one flies towards you

Course C

From Course C (adults: 4,600 yen for up to 5 people), a guide will be provided. This is because the roads are darker and narrower, and tourists may feel uneasy walking alone. The guides will be local high school students

Upon completion,a "Course C Completion Certificate"and a hot spring ticket. There is a hot spring nearby where you can warm up your body in the cold water.

What course do you recommend?

Course A is not particularly thrilling and is more of a tourist cave, not much different from Abukuma Cave. If you want to fully enjoy the charm of Irimizu Cave, then Course B or higher is the way to go

If you have small children, it is safer to choose Course B. Course C takes about 90 minutes to be served

If you are confident in your physical strength and determination, try Course C. However, because a guide is provided, you may not be able to choose this option in some cases

It's best to make a reservation in advance
