Guide
The Iwami Ginzan Kaido (Unazuki/Okihama route) is a historic trail used during the late 16th century when Unazuki and Okihama served as the administrative centers and outer ports for the Iwami Ginzan silver mine. The path spans approximately 12km, with widths varying between 0.8m and 3.3m, once supporting the heavy traffic of people, cattle, and horses. Today, it remains a precious historical site where traces of the logistics infrastructure—such as stone waymarkers, stone Buddhas, and the remains of stone quarries—still stand as a testament to the era's prosperity.
The route was developed starting from Sakane-guchi (elevation 220m) near the silver mine, passing through Saka-no-toge (elevation 420m), and leading to the Nishida settlement (approx. 100m elevation) to the west. The Nishida settlement functioned as a vital transit point, connecting the path toward Unazuki and Okihama via the Shimizu village. Along the way, stone towers and Buddhist statues were erected to pray for safe passage, reflecting the faith and daily life of the people of that time. The local culture remains alive today, seen in the small shrines in Nishida for fire prevention and the legends of pure spring water in the Shimizu village.
The trail is dotted with stone structures that evoke a deep sense of history. Notable features include the remains of stone quarries, well-maintained stone steps, and ancient drainage systems that showcase the advanced engineering of the period. A particular highlight is the Shimizu village, home to the legendary 'Kin-hishaku' (Golden Ladle) spring water. According to local lore, a silver mine official once offered a metal ladle at this site. This spring was once a vital spot for travelers to quench their thirst. The stone Buddhas and monuments along the path add a profound spiritual depth to the landscape, representing the prayers of ancient travelers.
Set within a lush natural environment, the trail offers a different atmosphere with each season. A special highlight occurs in August during the 'Suijin-sai' (Water God Festival) held in the Shimizu village. This traditional event celebrates the local spring water and offers a rare opportunity to experience the region's living history. For the best experience, we recommend visiting during the morning hours when the air is cool and the atmosphere of the forest and villages is most tranquil. While hiking during the day is standard, the shade of the trees provides a pleasant walk even in warmer months.
The primary activity is a historical walk tracing the logistics of the silver mine era. As you navigate the stone steps and gentle slopes, you will experience a seamless fusion of nature and history. Learning the local legends, such as those found in the Shimizu village, transforms a simple hike into a deep cultural immersion. It is a perfect way to connect with the past while enjoying the natural scenery.
The route connects the silver mine area (Sakane-guchi) through the Nishida and Shimizu settlements, eventually reaching Unazuki and Okihama. These coastal areas once thrived as major export hubs for silver and served as the vital endpoints of this historic trail. The entire area is a cohesive historical narrative composed of various shrines and ancient settlements.
