The park features a man-made 'Legend of the Dragon's Crystal' narrative to guide the excavation experience.
Gemstones are embedded in simulated riverbeds and rock formations to recreate natural mining environments.
The water-based indoor course allows for year-round operation regardless of outdoor weather conditions.
Some specialized, rare stones are intentionally hidden within the dig sites to provide high-value targets for lucky participants.
The park is located within the Nasu Highland area, a volcanic region known for its natural geology.
Treasure Stone Park in Nasu, Tochigi, specializes in interactive gemstone excavation experiences. Visitors can dig for semi-precious stones across two distinct settings: an indoor waterway course and a mountain-themed outdoor mine. The facility provides tools such as shovels and buckets, allowing participants to keep the treasures they find. The stones found range from quartz crystals to various colored agates and minerals. The park is designed for families and hobbyists interested in hands-on gem hunting. The site is located in the Nasu plateau region, known for its mountainous landscape.
The entrance display featuring large, raw crystal clusters provides the best lighting and background for photos.
Wear comfortable, closed-toe shoes as the floor near the water course can become wet.
Bring a small towel to wipe stones clean immediately after finding them to better inspect their quality.
Focus on digging in the corners of the troughs or near large rocks, as stones tend to accumulate in these crevices.
Do not rush through the outdoor mine; moving sand slowly allows for better visual detection of hidden stones.
Closed every Tuesday and Wednesday throughout the year, with additional maintenance closures occasionally scheduled in winter.
Return all borrowed tools to the designated cleaning stations after your session.
