Guide
Rokkanon Miike is a volcanic crater lake located in the northern part of the Ebino Plateau within the Kirishima Volcanic Group in southern Kyushu. The lake was formed approximately 20,000 years ago by a steam explosion (a maar), showcasing a concentrated masterpiece of natural formation. The water is highly acidic (pH 3.4–4.8), and due to its high transparency and depth, it displays a brilliant, vivid cobalt blue color under clear skies. The landscape is framed by a rich ecosystem of coniferous trees like fir and Japanese cedar, alongside deciduous trees such as oak and maple.
The site is steeped in legend dating back to the year 959. It is said that while a monk named Shoku was praying the Lotus Sutra by the lakeside, an old man appeared to him. The old man claimed to be Yamato Takeru and stated he resided in this mountain in the form of a white bird. Following this legend, Shoku carved six Kannon statues and established the Rokkanon-do shrine on the northern bank. Historical records also note that annual rituals were held at the shrine every September 28th during the Edo period.
The primary attraction is the breathtaking sight of the deep blue water. On sunny days, the color reaches a stunning intensity. To the north of the pond lies the historic Rokkanon-do shrine, creating a serene atmosphere in harmony with nature. Visitors can also see the
