Mt. Omoto

526m Elevation – Highest Peak in Okinawa

The highest mountain not only on Ishigaki Island but in all of Okinawa Prefecture, also known as "Ishigaki Fuji." The 526-meter elevation is the origin of Omoto526's name. On clear days, you can see the surrounding islands from the summit.

Iriomote-Ishigaki National Park – Special Protection Zone

Nationally recognized highest-level nature conservation area

The Mt. Omoto area is part of Iriomote-Ishigaki National Park, with portions designated as a "Special Protection Zone" where development is most strictly restricted. These regulations ensure the pristine nature remains protected today.

Route Overview

Round trip from trailhead to summit takes approximately 3–4 hours. An intermediate-level course with steep sections and maintained trails offering moderate elevation changes. Recommended for those confident in their fitness.

Summit Views

From near the summit, enjoy views of Ishigaki City, coral reef waters, and on clear days, surrounding islands including Iriomote and Taketomi. The spectacular scenery after passing through subtropical forest is unforgettable.

Best Season

November through March is recommended for cooler, more comfortable conditions. Summer brings high heat and humidity requiring early morning starts. Check conditions in advance during typhoon season (July–September).

Forest Road Walks Also Rewarding

Even the forest road before the trailhead offers a satisfying nature experience. Birdwatching, firefly spotting, plant observation—simply walking brings many discoveries.

Prime Comfortable Trekking

Cooler temperatures make this the most comfortable hiking season. Wintering birds join the forest, perfect for quiet communion with nature.

Start Early

We recommend departing around sunrise when birdsong is most vibrant. In summer, early starts are essential for heat management.

Wear Trekking Shoes

Trails become slippery after rain. Sandals or light footwear are dangerous. Please wear trekking shoes with solid grip.

Water & Insect Repellent Essential

Bring sufficient drinking water (1L+) and insect repellent spray. As habu snakes inhabit the area, avoid carelessly entering grassy areas.
