The cedar trees were planted by the feudal lords of the Matsushiro Domain in the early 17th century.
The trees average over 30 meters in height, creating a natural cathedral effect that obscures the sky.
The promenade leads to the foot of Mount Togakushi, a site historically significant for Shugendo, a syncretic Japanese religion of mountain asceticism.
The path is protected under the Cultural Properties Protection Act of Nagano Prefecture.
The specific tree species, Cryptomeria japonica, is endemic to Japan and prized for its rot-resistant wood.
The Cedar Promenade of Inner Togakushi, located in Nagano, is a nearly 500-meter-long approach lined with approximately 200 massive Japanese cedar trees. These trees, known as 'sugi,' were planted around 400 years ago during the Edo period. The pathway serves as the main access route leading directly to the Okusha (Inner Shrine) of the Togakushi Shrine complex. The trees are recognized as a prefectural designated natural monument due to their significant age and uniform spacing. The path features a gradual incline as it progresses toward the base of Mount Togakushi. A distinctive vermilion-lacquered wooden gate, the Zuishin-mon, marks the transition between the outer approach and the dense grove. The soil and root systems are protected to maintain the health of the ancient timber. Visitors walk along a cleared dirt path that maintains a constant canopy shade regardless of seasonal weather.

Wear sturdy, closed-toe walking shoes as the ground is uneven and can be muddy.
Bring an extra layer even in summer, as the temperature within the forest grove is significantly cooler than the surrounding area.
Stay strictly on the designated path to avoid compacting the root systems of the ancient trees.
Attempting the walk in formal footwear or high heels, and straying from the marked path into the forest undergrowth.
Access may be restricted during heavy winter snowfalls when the path becomes impassable.
Maintain silence to respect the spiritual nature of the Shinto shrine approach; do not touch or lean on the ancient trees.
