◆What Is the Shirataki Archaeological Site?｜A “Sanctuary of Obsidian” Dating Back to the Paleolithic Era◆

Engaru Town is located in northeastern Hokkaido, halfway between the Sea of Okhotsk and the Daisetsuzan mountains. This region, nurtured by rich forests and volcanic terrain, is home to one of Japan’s rare large-scale sources of obsidian. Due to its geological value and cultural heritage, the entire town has been designated as the “Shirataki Geopark,” recognized by the Japanese Geoparks Network.
Within the geopark, there are numerous Paleolithic sites, including the Kita-Shirataki Site No. 2, making it one of the largest such site clusters in Japan and drawing significant attention. The Shirataki Archaeological Site is a true “sanctuary of obsidian,” where nature and human history are intricately intertwined.

◆One of Only Two National Treasures in Hokkaido Is Found Here◆

In 2023, a group of stone tools unearthed from the Kita-Shirataki Site No. 2 was designated a National Treasure under the title “Artifacts Excavated from the Shirataki Archaeological Sites in Hokkaido.” The designation was granted because the tools clearly demonstrate the process of stone tool production, offering valuable insights into Paleolithic culture in the Japanese archipelago.
Hokkaido has only one other National Treasure—the “Hollow Clay Figure” from Hakodate City, which symbolizes the spiritual culture of the late Jomon period. In contrast, the Shirataki artifacts can be considered a National Treasure that tells the story of “technology” and “daily life.”

◆What Is Obsidian? Experience the Life of Paleolithic People◆

Obsidian is a natural glass formed by volcanic activity. Because it fractures into sharp edges, it was processed into tools like knives and arrowheads during the Paleolithic era, becoming essential to human life. Evidence also shows that it was used in trade with distant regions.
The Shirataki Geopark Exchange Center offers hands-on experiences where visitors can “see, touch, and learn” about how obsidian was formed and used. Programs include stone tool making, fire-starting experiences, and accessory crafting—all designed to engage the five senses.
