It is historically considered the most difficult mountain temple on the Shikoku pilgrimage trail, known as a 'henro-korogashi' or 'pilgrim fall' section.
The temple grounds are home to a forest of ancient cedars, some reaching heights of over 30 meters and protected as prefectural natural monuments.
A local legend describes a dragon that once terrorized the area until it was subdued by the monk Kobo Daishi and bound to a stone.
The temple was founded in the late 7th century by the monk En no Gyoja and later revitalized by Kobo Daishi.
The temple sits at an altitude of approximately 700 meters, requiring a significant ascent regardless of the direction of arrival.
Shosan-ji, the 12th temple of the 88-temple Shikoku Pilgrimage, is known as the 'toritsuke-dera' or 'difficult mountain temple' due to its steep 700-meter elevation gain. Located deep in the mountains of Kamiyama, it is one of the most physically demanding stops on the pilgrimage route. The temple grounds feature ancient cedar trees, some estimated to be over 800 years old, which provide a dense canopy over the path. The main hall, Shaka-do, houses a statue of Shaka Nyorai, while the site is associated with legends of a dragon that once lived in the area. Pilgrims traditionally stop here after completing the arduous hike from Temple 11, Fujii-dera. The temple layout is integrated into the mountainside, requiring constant walking on stone stairs and earthen paths. Its remote location ensures a high degree of seclusion compared to temples located in urban centers.
The path through the ancient cedar forest leading to the main hall offers the most iconic perspective.
Wear high-traction hiking footwear as the mountain paths are steep and can be slippery in damp conditions.
Carry sufficient water and snacks, as there are no shops or vending machines once you begin the forest ascent.
Check local weather forecasts specifically for the Kamiyama mountain range, as conditions can differ significantly from the lowland plains.
Attempting the ascent in heavy rain or low-visibility fog, as the mountain trails become hazardous.
Maintain silence, follow the path markings, and do not step on the grass or protected forest roots.
