Akiyoshido (秋芳洞)
Akiyoshidai, in the eastern part of Mine City in Yamaguchi Prefecture, is home to the “Akiyoshido,” Japan’s greatest limestone cave. The entrance to the cave has a height of 24 meters and a width of eight meters, and the cave’s deepest point is about 200 meters below the surface. There are plenty of sights to see such as the giant Golden Pillar, a travertine pillar with a height of approximately 15 meters, and the Hundred Saucers, which look like terraced rice-fields. The interior of the cave stretches for nearly 10 kilometers, but the sightseeing path only ventures to about one kilometer into the cave. The temperature remains stable at nearly 17°C throughout the year, and a wide range of ages can comfortably tour the cave.

Yamaguchi Areas

Heading west along Japan’s largest island, Honshu, the very last prefecture you’ll reach is Yamaguchi, separated from Kyushu by a small strip of water known as the Kanmon Straits, which the far-reaching harbor city Shimonoseki looks over. With water at every turn, the seafood of Yamaguchi is an indisputable highlight, and we’re not talking just the usual fish dishes - the notorious fugu, or puffer fish, is a Japanese delicacy that was discovered in Yamaguchi prefecture, making it the best place to try it out.
