Located on the western coast of Chiba’s Boso Peninsula, Mount Nokogiri (鋸山) is a landmark defined by its rugged silhouette and deep spiritual history. Known in English as “Sawtooth Mountain,” its jagged profile is the result of extensive stone quarrying during the Edo period. The high-quality stone harvested here, known as houshuishi, was highly valued for its durability and ease of cutting. It played a significant role in the construction of various structures around Tokyo Bay, including the coastal fortresses that would eventually evolve into the modern-day district of Odaiba.

The mountain is home to Nihon-ji, a Buddhist temple founded over 1,300 years ago by imperial decree. Today, its most famous feature is the Nihon-ji Daibutsu, Japan’s largest stone-carved Buddha. Completed in 1783, this monumental representation of the Healing Buddha stands at over 31 meters—towering above the more famous bronze counterparts in Nara and Kamakura. Although earthquakes and the passage of time have affected the structure, a major restoration in 1966 preserved its grand presence for future generations.

Scattered throughout the mountain’s shaded grottoes and rocky alcoves are the 1,500 Tokai Arhats. These miniature stone disciples were carved by the same master sculptor responsible for the Daibutsu, Jingoro Eirei Ono, alongside his 27 apprentices. While the early Meiji era saw the destruction of many Buddhist relics in favor of Shintoism, roughly 500 of these expressive statues remain today, hidden within caves and along the steep trails.
For many, the climax of a visit is Jigoku Nozoki, or the “Peek into Hell.” This rock platform juts out from the mountain face, suspended approximately 100 meters above the ground. While it offers a vertigo-inducing photo opportunity, the surrounding summit provides an even more impressive 360-degree panorama. To the west, the ocean flows into Tokyo Bay with Mount Fuji often visible on the horizon, while to the east, the lush green hills of the Boso Peninsula stretch as far as the eye can see.

Though the mountain stands at a modest 330 meters, the terrain is physically demanding due to a vast network of stone stairs. While a ropeway and a toll road provide access to the upper levels, exploring the various statues requires a considerable amount of walking. Visitors are advised to bring their own food and water, as facilities on the mountain are limited to a few vending machines. The experience remains one of Japan’s most unique combinations of industrial history and spiritual art.
