Mount Nokogiri (Nokogiriyama) is a mountain spanning Futtsu City and Chosa Town in Chiba Prefecture, recognized as a candidate for Japan Heritage. The area is characterized by a striking landscape where the industrial ruins of massive stone quarries on the Futtsu side meet the sacred Buddhist sites of Nihon-ji Temple on the Chosa side. The scale of the stone quarries is considered a significant subject of study due to its rarity in Japan, offering a space where industrial history and natural beauty are seamlessly integrated.
On the southern slope of Mount Nokogiri lies Nihon-ji Temple, which is said to have been founded approximately 1,300 years ago by the monk Gyoki under an imperial decree from Emperor Shomu. As one of the oldest temples in the Kanto region, it has served as a center of worship for centuries. The area has also been a beloved destination for travelers from the Edo period to the present day. The stone quarries serve as vital historical remains that tell the story of the region's industrial past.

The grounds of Mount Nokogiri are dotted with diverse historical structures. Notable sites include the Great Buddha of Nihon-ji (Yakushi Ruri Kokuryo), the towering Hyakushaku Kannon statue, and the impressive collection of 1,500 Arhat (Rakan) stone statues. Another must-see is the 'Jigoku Nozoki' (Hell's Lookout), a breathtaking cliff edge offering panoramic views. These sites create a unique atmosphere where natural topography meets man-made historical craftsmanship.
The scenery around Mount Nokogiri changes beautifully with the seasons. The months from March to May and September to November are particularly wonderful for observing the changing vegetation and natural landscapes. While daytime is the best time to explore the details of the quarries and Buddhist ruins, please note that the terrain is complex; traveling during bright daylight hours is highly recommended for safety.

Visitors can enjoy hiking through historical sites, following routes that pass through the stone quarries and the sacred grounds of Nihon-ji. In the past, educational monitor tours have been held to teach visitors about the local topography and vegetation. Please be aware that some paths may lack formal walkways, so checking the current trail conditions in advance is advised.
The nearby areas of Kanaya and Hota are known as the 'Kanaya/Stone Towns.' Depending on which side of the mountain you explore, you can experience different historical contexts: the industrial quarry ruins in Futtsu or the spiritual Buddhist sites in Chosa. You can also access the area via the Tokyo Bay Ferry, arriving at Hama-Kanaya Port.
Mount Nokogiri is a mountainous area with many stairs and uneven surfaces. Sturdy, comfortable walking shoes are mandatory. Some walking paths may occasionally be closed due to rockfalls, so please check for the latest updates.
