Kosanji Temple's Underground World: The Cave of 1,000 Buddhas and Jigoku Gorge

Mount Fuji Lava Crafts the Walls of Kosanji’s Senbutsu Cave

Beneath the vibrant temple grounds of Kosanji lies a remarkable and profound journey: the 千佛洞地獄峡 ⭐, often referred to as the Cave of 1,000 Buddhas. This ambitious underground project, nine years in the making, began in 1955 and was finally completed in 1964.

The entrance to this subterranean world is subtly placed next to the elegant Shishinden Hall 至心殿, on the west side of the main temple building. From there, visitors descend about 15 meters underground into a winding tunnel, stretching an impressive 350 meters. The very walls of this unique cave are a testament to human ingenuity and artistic vision: they were meticulously formed using hardened lava from Japan's iconic Mount Fuji and burnt stones from Mount Asama, all reinforced with concrete to create naturalistic rock formations.

Beyond the serene Buddhas, vivid plaques line the cave walls, portraying scenes of Buddhist hell and paradise. These powerful images bring teachings of karma, consequence, and rebirth to life, inviting quiet reflection on the journey of the soul.

As you navigate the cool, dim passages, you'll discover three vast caverns, each roughly 10 meters high and spanning several tens of square meters. These expansive spaces are not merely structural; they serve as a canvas for the cave's spiritual purpose. Inside, a thousand serene stone Buddha statues stand enshrined, their presence adding to the sacred atmosphere. There's even a subterranean waterfall, its gentle rush echoing through the depths. 

The photographs taken on December 3, 2024, beautifully capture this essence, serving as a visual testament to the cave's religious allure.
