## What Is the Iwami Ginzan World Heritage Site?

Iwami Ginzan is one of Japan’s most significant silver mine sites, located in Ota City, Shimane Prefecture.

Full-scale development began around the 1520s, and the mine flourished throughout the Edo period as one of Japan’s leading silver-producing areas.

During the 16th and 17th centuries, Japan became one of the world’s leading silver-producing countries, and Iwami Ginzan played an important role in that development. Silver from Japan was used in trade with East Asia and Europe, and is believed to have had a significant impact on the global economy.

Iwami Ginzan was registered as a World Heritage Site not simply because of its mining remains, but because the following elements have been preserved together in good condition:

- Mine ruins
- The remains of refining facilities
- The mining town
- Roads and routes
- Ports

The fact that mining was carried out in harmony with the natural environment was also highly valued.

## The Large Diorama in the Entrance Hall

The first thing to catch visitors’ attention after entering the center is the large diorama recreating the entire Iwami Ginzan site.

It presents the terrain within the World Heritage area and the various ruins in three-dimensional form, allowing visitors to understand at a glance the locations of:

- Ryugenji Mabu Mine Tunnel
- Okubo Mabu Mine Tunnel
- The historic streets of Omori
- The Ginzan Kaido silver mine road
- Yunotsu Port
- Tomogaura

Because the Iwami Ginzan sites are spread across a wide area, the diorama is useful for planning an efficient sightseeing route.

## Highlights of the Exhibition Rooms

### Exhibits on the History of Iwami Ginzan

The exhibition rooms provide a detailed introduction to approximately 400 years of history, from the discovery of Iwami Ginzan to the closing of the mine.

During the Sengoku period, powerful clans such as the Mori and Amago fought to control the mine. During the Edo period, it was managed by the Tokugawa shogunate as an important mine under direct government control.

Visitors can learn about the changes that took place during each period through historical materials, videos, and other exhibits.

### Silver Mining and Refining Techniques

Iwami Ginzan employed mining and refining techniques that were advanced for their time.

One especially famous technique was the “haifuki” cupellation method. This refining process made it possible to extract silver efficiently and played a major role in the development of Iwami Ginzan.

The center uses models and videos to explain how the technique worked in an easy-to-understand manner.

### Reproduction of the Okubo Mabu Mine Tunnel

Inside the center is an exhibit reproducing part of the Okubo Mabu mine tunnel.

The exhibit recreates the atmosphere inside the tunnel, allowing visitors to imagine the conditions in which miners worked. The narrow, dark passageways convey the harshness of mining operations at the time.

### Large Silver Nugget Exhibit

The exhibition rooms also feature a large silver nugget that visitors can actually touch.

Many people are surprised by its weight, which is greater than it appears. It is one of the center’s most popular interactive exhibits, allowing visitors to experience the weight and value of silver as a metal.

### VR and Video Exhibits

The center also offers interactive exhibits featuring virtual reality and video theaters.

The videos introduce:

- Iwami Ginzan during its peak period
- The interiors of the mine tunnels
- The silver refining process
- Life in the mining town

These exhibits provide a more vivid and comprehensive understanding of what Iwami Ginzan was like in the past.

They are popular with visitors of all ages as a fun way to learn about the site.

## Hands-On Programs

The Iwami Ginzan World Heritage Center also offers hands-on programs at certain times of the year.

### Crafts Inspired by Chogin Coins

Depending on the season, visitors may be able to make keychains, straps, and other items inspired by chogin, a type of silver coin that circulated during the Edo period.

Because low-melting-point alloys are used, this is a relatively safe and enjoyable activity. It is also a great way to make a souvenir of your trip.

### Silver Searching Experience

At certain times of the year, the center may offer a “silver searching” activity, in which participants look for tiny pieces of silver in sand.

In some cases, participants may be allowed to take home the silver pieces they find. This activity is especially popular with families traveling with children.

*Since the dates and contents of hands-on programs may change, visitors are advised to check the latest information before participating.*

## Ideal Preparation for Exploring Iwami Ginzan

Because the Iwami Ginzan sites are spread across a vast area, visitors may not fully understand their significance or historical background if they explore them without any prior knowledge.

After studying the site at the World Heritage Center, visitors will be able to appreciate attractions such as:

- Ryugenji Mabu Mine Tunnel
- Okubo Mabu Mine Tunnel
- The historic streets of Omori
- The Ginzan Kaido silver mine road
- The remains of refining facilities
