Sanbon Sugi (Three Cedars of Mt. Oiwa)

Overview & Charm

The Sanbon Sugi (Three Cedars) is a rare and extraordinary specimen located near the approach to Oiwa-yama Shrine in Hitachi City, Ibaraki Prefecture. The most striking feature is its three massive trunks that diverge from a single base at approximately 3 meters above the ground, stretching toward the sky. This breathtaking sight serves as a powerful symbol of life and natural vitality. The tree is a Japanese Cedar (Sugi) with an estimated age of 500 years, a trunk circumference of 8.4 meters, and reaches a height of 40 meters. Whether these three trunks originated from a single tree or are three trees that have fused over centuries, they represent a masterpiece of natural architecture.

History & Cultural Background

The area surrounding Mt. Oiwa has a long history, recorded in the ancient 'Hitachi no Kuni Fudoki' as a sacred landscape. The region holds deep spiritual significance, with archaeological evidence of rituals dating back to the Jomon period. Historically, it served as a site for ascetic training (Shugendo). Oiwa-yama Shrine is said to be home to 188 deities, deeply connecting the site to Japan's traditional nature-based spirituality. The Sanbon Sugi has been revered and protected by local people and pilgrims for generations, embodying the Japanese spirit of honoring the divinity found within the natural world.

Main Highlights

The primary attraction is the sight of the three massive trunks ascending powerfully toward the sky. The way they branch out just a few meters above the ground creates a profound impact on all who visit. As a designated Natural Monument of Ibaraki Prefecture (designated in 1968), the tree holds significant historical and academic value. Visitors can feel the breath of life from a tree that has survived for over five centuries amidst the serene atmosphere of the deep forest.

Recommended Seasons & Times

While the Sanbon Sugi maintains its powerful presence year-round, the surrounding forest offers different expressions depending on the season. Visiting during the fresh greenery of spring or the vibrant colors of autumn provides a beautiful harmony between the giant cedar and its environment. We highly recommend visiting in the early morning; the forest air is at its clearest and most refreshing, enhancing the sacred and tranquil atmosphere for contemplation.

Experiences & Activities

Visitors can enjoy 'Shinrin-yoku' (forest bathing) by observing the natural architectural beauty of the trees, combined with a visit to the sacred Oiwa-yama Shrine. Witnessing the overwhelming scale of the Sanbon Sugi fosters a deep sense of awe and respect for nature. The surrounding area also features well-maintained hiking trails, allowing you to experience the historical background and natural wonders through all your senses.

Surrounding Area

The vicinity of Mt. Oiwa is dotted with historical sites and natural landmarks. For example, the Satsu Jinja Okumiya is a historically significant site rediscovered through topographical surveys. Oiwa-yama Shrine itself is a renowned 'power spot' (spiritual energy site), and visitors can hike toward the summit (530m altitude), where stone monuments dedicated to historical figures like Mito Mitsukuni and Mito Nariaki can be found.
