Irimizu limestone cave is located in Tamura City in Fukushima Prefecture.
Spelunking (or cave trekking/caving) is a thrill in this real cave. After the entrance, the 900 meter long area is divided into A, B, and C courses, all somewhat narrow. The B course goes farther back and a flashlight is a necessity because this rather undeveloped space gets a little hairy. It is wet, the water only 10 degrees; and you must crawl on all fours to avoid stalactites. The farthest, C, requires you to have a guide.
