Akiyoshidai

Overview

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.
