I went in October and was mesmerized by just how beautiful the Tohoku foliage is. The colors are so much more vibrant than the rest of Japan. The wetlands were a bit tricky because they made my hiking shoes all dirty. So, make sure to wear proper hiking shoes, especially waterproof ones with high ankles.

Starting Point: Sukayu Onsen, a popular hot spring facility known for its “1,000-person bath.” The onsen makes for a perfect start and end to your hike, giving you a chance to relax and refresh after exploring the mountains.

Trail Details:

• Distance: 9 km loop trail

• Elevation Gain: 700 meters

• Time Required: 5 hours for the main loop

Route Description:

• Starting Ascent: From the Sukayu Onsen Trailhead, follow the signs leading into the forest. The trail starts with a steady climb through dense trees, and the path can be wet and muddy, so proper footwear is essential.

• Marshlands and Open Meadows: About halfway up, the trail opens into marshlands with wooden boardwalks, which protect the fragile ecosystem while giving you views of the surrounding peaks. During late spring and summer, the area is rich with wildflowers.

• Summit Approach: As you continue, the trail becomes steeper, and the terrain turns more volcanic, with rocky paths leading up to the primary summit, Mt. Odake (1,585 meters). On a clear day, you’ll have unobstructed views of Aomori City, Mutsu Bay, and even Hokkaido in the distance.

• Return Loop: For a complete experience, take the loop trail back down to Sukayu Onsen, passing through scenic open areas that give you a different perspective on the mountains.

Tips:

• Best Season: The hike is most accessible from mid-May to early November, with October offering particularly beautiful autumn foliage.

• Gear: Bring sturdy, waterproof hiking boots, as sections of the trail can be muddy. Trekking poles are also recommended for steeper parts.
