Akiyoshidai and Akiyoshido

Nestled within Mine City, Akiyoshidai Park is home to a landscape not found anywhere else in Japan—a vast hilly grassland speckled with pure white kalst stones. 350 million years ago, this entire area was actually underwater! The rocks are the remains of a coral reef and other sea creatures compressed into limestone deposits over the millennia. Fossil remains have even been found within the rocks and surrounding area, including the bones of a mammoth deer!

At the Akiyoshidai Observation Deck, a 360-degree panoramic view of the park can be enjoyed, and walking trails guide travelers through the stone-dotted terrain. The landscape echoes the seasons as fall dyes the green plains of summer and spring into deep hues of auburn and orange. Stemming from a 600-year-old tradition, every February the grasses that have withered over in the winter are set aflame during the annual yamayaki (mountain burning) festival. The fires burning bright in the darkness of night are an otherworldly spectacle to behold. From the scorched earth, verdant green grass will sprout anew in the spring.

At the Akiyoshidai Museum of Natural History you can see the fossil remains of animals and sea creatures that lived in the ancient era when Japan was still connected to the Eurasian continent. With permission from the museum, you can even dig for your own fossils to take home.

To the south of Akiyoshidai lies the Akiyoshido, where a 1-km course will take you through a dreamscape of surreal beauty and fascination. Stalagmites cascading to the floor like golden waterfalls frozen in time, and stalactites that stretch out like terraced golden rice fields—these are but a few of the myriad natural wonders on display at the Akiyoshido.
