While the hike itself is not that much fun, the view of the lake is beautiful.

Highlights Along the Trail

• Lake Ono (Onuma): The trail starts by winding along Lake Ono, a serene crater lake at the base of Mt. Akagi. The lake’s surroundings are especially beautiful during autumn when the foliage transforms into vibrant colors. Take in the reflective, peaceful scenery as you start your ascent.

• Akagi Shrine: Located on the shores of Lake Ono, Akagi Shrine is a spiritual and cultural landmark revered for centuries. The shrine, dedicated to the deity of Mt. Akagi, is known for its striking red torii gates and tranquil setting on the lake’s edge. Many hikers stop here for a moment of reflection and to enjoy the historic atmosphere.

• Summit Views: After ascending through lush forests, you’ll reach the summit of Kurobi-dake. The panoramic views here, especially on a clear day, stretch across the Kanto Plain and surrounding mountains, offering a rewarding sight for the effort of the climb.
