East Asia’s Largest Limestone Cavern

Many are the tourist destinations that can be compromised, if not downright spoiled, by rainy weather. Not so a cave, especially a massive one with stalactites, stalagmites, rimstone dams and a surreal, subterranean river. Here in Japan, where you might find yourself with consecutive days of wet weather, beautiful Akiyoshi cavern in Yamaguchi Prefecture will not disappoint.

And if you have school age children, seriously bored with the history and spirituality of shrines and temples and gardens, a journey into this labyrinth will revive both their senses and imagination.
It’s a good kilometer trek from one end of the cavern to the other. The path is well lit and never difficult. Plan to walk the entire distance, including the final tunnel of several hundred meters to the exit, as there is much to see all along the way. The variety of limestone formations is truly impressive, the glassy waters luminescent and dreamlike.

An interesting human artifice is found somewhat beyond the midpoint of the cave, where an elevator (price included in the entry ticket) will whisk you from the subterranean darkness to the ephemeral landscape above, several thousand feet above sea level. Here, a karst plateau, the Akiyoshi Highlands, roll away like scenery out of a Nordic fantasy.
Alternately, you can pass the elevator and walk to the end of the cave, and from there hike up the trail up to the highlands. Do some exploring around the highland observatory, then ride the elevator back down into the cave for the return walk. Obviously, if you do it this way, you will walk more uphill; if you take the elevator up, and walk down to the upper entrance to the cave, walking the full length back, it’s more downhill.

Softserve macha ice cream, sold at the upper end of the cave, offers a just reward for a few hours of adventuring.
Akiyoshido Cave is an easy 45-minute bus ride from Shin Yamaguchi (shinkansen) Station. It’s a wonderful side excursion, whether you’re caught in a rainy spell or not!
