Nokogiriyama

With its sheer cliffs, ancient stone carvings, and dramatic ocean views, Nokogiriyama, or “Sawtooth Mountain,” feels like a place pulled straight out of a legend. Located on the Boso Peninsula in Chiba Prefecture, it’s an easy day trip from Tokyo but far removed from the city’s pace and skyline.

Known for its massive stone quarry, mountaintop temple, and breathtaking panoramas over Tokyo Bay, Nokogiriyama is the kind of place that surprises even seasoned Japan travelers.

Why Is It Called ‘Sawtooth Mountain’?

Nokogiriyama (鋸山) literally means “Saw Mountain,” named for its jagged ridgelines that resemble the teeth of a saw. Its steep stone faces are the result of centuries of quarrying, as the mountain was once used to harvest stone for castle walls and temple buildings across the region.

Today, the dramatic cuts into the rock add to the mountain’s unique look and spiritual intensity.

Jigoku Nozoki – The “View Into Hell”

Jigoku Nozoki

The most famous and slightly terrifying spot on Nokogiriyama is the Jigoku Nozoki (地獄のぞき), or “View Into Hell.” This narrow rock ledge juts out from a cliff, offering a dizzying view straight down into the former quarry and beyond to Tokyo Bay.

It’s perfectly safe, with railings and clear signage, but stepping out onto the overhang gives most people a slight chill. The view, though, is unforgettable, especially on clear days when you can see as far as the Miura Peninsula, Tokyo skyline, and even Mount Fuji.

Nihon-ji Temple (日本寺)

The spiritual heart of Nokogiriyama is Nihon-ji, a sprawling mountaintop temple complex with over 1,300 years of history. It’s most famous for:

Japan’s Largest Seated Stone Buddha

Standing at 31 meters tall, the massive Daibutsu (Great Buddha) of Nihon-ji is the largest of its kind in Japan, even taller than the Great Buddha of Kamakura or Nara. It’s carved directly into the mountain face and has an overwhelmingly calm presence.

1,500 Arhat Statues (Rakan)

Spread across the forested paths and cliffsides are rows of small stone statues of Buddhist disciples, each with a unique expression and pose. Many were damaged during anti-Buddhist movements in the Meiji era, but restoration efforts have brought hundreds back to life.

Walking among these silent figures creates a surreal, contemplative mood that makes this site unlike any other temple in Japan.

Hiking and Ropeway

There are two main ways to reach Nokogiriyama:

Option 1: Hiking Trails

There are well-marked trails that start from Hama-Kanaya Station and climb up through forest and stone steps. It takes about 40–60 minutes to reach the main viewing points. The hike is moderately challenging but rewarding, especially if you enjoy getting off the tourist track.

Option 2: Nokogiriyama Ropeway (鋸山ロープウェー)

If you prefer a more relaxed trip, take the ropeway from the base up to the mountaintop. The ride only takes a few minutes and offers fantastic views over the bay as you ascend.

Once at the top, there are walking paths that lead to Jigoku Nozoki, the Daibutsu, and other key points.

A Place of Contrast

What makes Nokogiriyama special is its contrast. You’ll go from peaceful Buddha statues to heart-racing cliff views, from dark forested paths to wide-open ocean horizons. It’s spiritual, scenic, and slightly surreal, all in one mountain.

Despite being just 90 minutes from Tokyo, it’s still relatively uncrowded. On weekdays or early mornings, you may find yourself walking alone among the statues or standing at the cliff’s edge in complete silence.
