Japan’s longest cave awaits your exploration

Japan’s longest cave awaits your exploration

by Lily Crossley-Baxter

Caves. Not everyone’s a fan. If you are though, Yamaguchi boasts the longest in Japan, and it’s quite spectacular. The cave scene might be a bit of an underground movement, but with spelunking an option, the depths people will go to to reach them are ever-increasing.

Akiyoshido Cave is underneath the Akiyoshidai Quasi-National Park which is a strange landscape of almost-artificial-looking rounded hills with protruding white limestone rocks. When the acid in rainwater eats away at the limestone, the giant pits are created which eventually led to the cave formation, and the amazing stalactites and stalagmites within. You can visit the observatory and enjoy the views, follow some of the many hiking trails or attend in February when they burn the mountainside to control plant growth over a period of 3 hours, with 1000 local volunteers.

This all feels like a warm up though, in comparison the the draw of the dark caves below. The cave was named by Emperor Akihito in 1926 when he visited and has since been declared a Special Natural Monument. It reaches heights of over 80 m and is about 10 km long. As the water drips down around you, the transformation of the cave continues eerily. There are 6 types of cave bat and other small wandering creatures you can either hope to see, or actively avoid.

Depending on how you arrive, you can choose whether you would like to follow the ascending trail from the Akiyoshido entrance (left side of the map) or descending from the Kurotani entrance. There is also an elevator that joins Akiyoshido plateau with the cave, and this is about 300 m from the Kurotani entrance (right side). Both entrances have bus access and visitor centers, although personally it was nicer to follow the descending path as you exit through the lovely bridged area into a forest (very nice after a bit too long in a cave). From the Akiyoshido entrance, approximately one-third of the cave can be toured by wheelchair. Word of warning, take a jacket as it is always about 17 degrees Celcius (62 Farenheit) in the cave and if you’re taking your time it can get chilly.

Once you’re in, there are certain highlighted spots along the trail including the Golden Pillar, Hundred Saucers and the Thousand Rice Fields. There are 23 other creatively names sites to see which are less impressive, but look out for the Rain Palace, Jellyfish Climbing a Waterfall and The Dragon’s Secret Passage. There is even a small extra trail you can climb for 300 yen which takes you higher up, with a great view of the caves. Near all of the main sites are speakers where you can select your language and listen to a short description of the site you are near, as it is broadcast across the cave.

The Akiyoshido exit/entrance is lovely, and if you follow the path you’ll find yourself in a quiet, narrow souvenir- shop-lined street.

If you can’t get enough of caves, there are two more located in the Quasi-national park. Taishodo caves boasts sights such as ‘Entrance to Hell’ and the ‘Cattle Hiding Cave’ which you can explore. It is a vertical lime cavern with an upper level (Paradise Plaza) and a lower level, simply called ‘hell’.

If you make it out alive, you can venture to Kagekiyodo is a limestone cavern in which Heike Warlord Taira-no-kagekiyo hid after losing a battle. The ceilings and walls are considered particularly beautiful as they are covered with coral fossils. You will be given a helmet and head torch and you can explore the cave yourself including a “hands-on” route where you can go exploring with rental kit. These caves are also accessible from Shin-Yamaguchi Station, but transport in-between is not clarified.
