Akiyoshidai is expansive, so please wear comfortable shoes and clothing. Depending on the weather, temperatures can drop significantly, so don't forget to dress warmly.
Please note that some facilities, such as Akiyoshido Cave, require separate entrance fees.
Akiyoshidai, located in Mine City, Yamaguchi Prefecture, is one of Japan's largest karst plateaus, boasting a vast expanse of approximately 300 square kilometers. Its unique landscape features exposed white limestone bedrock.
Akiyoshidai was formed about 350 million years ago when coral reefs rose above sea level. Over countless years, rainwater and groundwater eroded the land, shaping the karst topography we see today.
The allure of Akiyoshidai extends beyond its breathtaking scenery. The karst landscape, characterized by various dolines (sinkholes) and exposed limestone formations, captivates visitors.
Akiyoshidai is home to numerous caves, including Akiyoshido Cave, one of Japan's largest. These caves reveal a mysterious underworld, with Akiyoshido Cave stretching over 10 kilometers, containing various stalactites and stalagmites, underground lakes, and subterranean rivers—a truly awe-inspiring testament to the Earth's wonders.
Furthermore, Akiyoshidai is a haven for diverse flora and fauna. Enjoy seasonal wildflowers, including skunk cabbage and bog arum in spring, tiger lilies in summer, and gentians in autumn.
Various facilities enhance the Akiyoshidai experience, such as the Akiyoshidai Karst Observatory and the Akiyoshidai Geopark Center Karstar. The observatory offers panoramic views of the vast karst plateau, while the Karstar features exhibitions about the Akiyoshidai Geopark and a relaxing cafe.
Akiyoshidai is a beloved destination where you can connect with Earth's history and the power of nature. Experience its charm firsthand!
