Mount Taisen

Mount Taisen is a summit within Aso-Kuju National Park that rises 1,786 meters and overlooks the Oita Prefecture landscape. The peak can be reached from several directions and features forest coverage along with volcanic formations typical of the region.

The third feudal lord of the Oka domain selected this peak as his final resting place and established the Iriyamakobyo Cemetery with views of the surrounding lands. This decision transformed the location into a significant monument of the feudal period in the region.

The summit connects to Gokurakuji Temple, where stone lanterns and carved steps reflect longstanding spiritual practices tied to mountain veneration. These structures show how locals have incorporated the peak into their religious life over generations.

The trail begins at Kusumi Kogen Palclub Resort and takes about four hours to reach the summit, covering roughly 26 kilometers in total distance. Sturdy footwear and plenty of water are important because sections become steep and shelter spots are limited along the route.

Below the summit lies Oike Pond nestled within a volcanic crater, reflecting red maple leaves and pink azaleas depending on the season. The contrast between the dark water and the bright plant colors creates a distinctive sight that visitors often miss.
