Facts & Figures

The town of Omori in the Shimane Prefecture was once a boomtown when the Silver mine’s production started. It was a bustling place full of merchants, craftsmen, government employees, and samurais. Today the town has a remaining population of approx. 450 people. Japan Rail Pass Buy now and Save >
Since 2004 I have traveled nearly every year to Japan. The rail pass made my life easier to discover all those amazing places in my favorite country.
Nearby you could find hundreds of silver mines of various sizes. The town quickly became the management and administration center of the Iwami Ginzan Silver Mine. Since Omori achieved together with the Iwami Silver Mine the status of a UNESCO World Heritage Site many visitors come here every year. Follow the 1,5km long main road called Omori Street within the Ginzan River Valley and enjoy cafes, restaurants, souvenir shops, galleries, temples, and shrines. The street leads to the Iwami Ginzan Park. Omori has one of the best-preserved historical districts in Japan. You can compare the traditional Japanese architecture with places like Narai and Tsumago in the Kiso Valley. You won't see any modern buildings from the 21st century during your sightseeing tour and all the power and telephone lines are buried. As a first point of contact, you should visit the Tourist Information. The staff is really helpful and English speaking. My tip: Rent a bicycle there and explore this place on your own.


Omori Town was once home to a silver mine which provided employment for residents in the region centuries ago before it finally closed its doors in 1923. In the beginning, the nearby Iwami Silver Mine was established in the early 1500s, it was under the direct control of the shogunate. Like most historical boomtowns, Omori (Street) was doomed to suffer after the mine’s production started to decrease in the early 1920’s. This sharp decline caused a huge chunk of the population to move away, which led to the steady decline of what used to be one of the most vibrant streets in Japan. Today, Omori Street is still inhabited by a few elderly residents, most of whom still care for the main street. In 2007 after intense lobbying by the Japanese government, Omori Street and the Iwami Silver Mine, in particular, was named a UNESCO World Heritage Site.
