Guide
The Nenshi Museum, located in Wakasa Town, Fukui Prefecture, is a specialized institution dedicated to geochronology and archaeology. Its most significant feature is the exhibition of 'Nenshi' (annual laminations) discovered at the bottom of Lake Suzu, one of the Mikata Goko lakes. These Nenshi are incredibly fine, layered sediments that represent a continuous record of approximately 70,000 years—a find of immense global scientific value. Beyond its scientific importance, the museum is celebrated for its striking architecture, having received the 61st BCS Prize for its exceptional design.
Research into Lake Suzu began in 1991, leading to groundbreaking discoveries during boring surveys starting in 2006. Because the lake lacks large river inflows and maintains a stable environment without biological disturbance, the sedimentary layers remained perfectly intact. This 'miraculous sediment' provides extremely high-precision data for radiocarbon dating. In 2012, at a global radiocarbon conference in France, these layers were recognized as a world-standard for geological dating. This scientific milestone was established through international collaboration involving research teams from Japan, the UK, and Germany.
The centerpiece of the museum is the actual 45-meter-long Nenshi specimen. Displayed as thin-section specimens encased in epoxy resin, visitors can witness the breathtaking layers of time spanning 70,000 years. The museum also offers extensive exhibits on how these layers form, comparisons with other Nenshi sites worldwide, and insights into paleoclimatology (the study of past climates). To enhance the learning experience, many exhibits utilize QR codes, allowing visitors to engage with digital explanations and deep-dive into the scientific data.
The museum is situated within the scenic Jomon Roman Park. The surrounding scenery and even the designs of the museum's stained glass may change with the seasons. For instance, special stained glass motifs inspired by the Nenshi (such as the 2025 designs) offer a seasonal touch to the visit. During the daytime, the bright, natural light through the modern glass architecture provides a perfect setting to enjoy the scientific exhibits and the surrounding landscape.
Visitors can experience the process of scientific discovery through interactive learning. The use of QR codes for digital explanations provides a visual and modern way to deepen your understanding of geology. Additionally, the museum occasionally hosts special opportunities; for example, during local events like the 'Wakasa/Mikata Goko Two-Day March,' certain admission benefits may apply. It is a destination for intellectual exploration of Earth's history.
Located within Jomon Roman Park, the museum is adjacent to the Wakasa Mikata Jomon Museum and the Jomon Colosseum. The area is also known for the beautiful views of the Mikata Goko lakes and is close to 'Michi-no-Eki Mikata Goko' (roadside station). After your visit, we recommend exploring the nearby historical sites and natural landscapes that define this region.
To fully enjoy the exhibits, it is highly recommended to bring a smartphone or tablet, as many explanations are accessed via QR codes. Please check the latest information regarding payment methods, English support, and reservation requirements before your visit. As a museum, please maintain a quiet atmosphere to respect other visitors.
