The Crafts Studio Village is a facility in which you can experience the traditional crafts of garment weaving, indigo dyeing, paper making, pottery making, and wood bamboo crafting in Aikawa Town’s prefectural Aikawa Park.

It is a fun way to learn about the history of traditional crafts.

You'll be amazed by the impressive scenery from all seasons! In addition, the "Adventure Forest" and the "Fluffy Dome" are equipped with large playground equipment that allow children to play all day long, and during the water season, the "Jabu-Jabu Pond" is filled with the sound of children's cheers all year round. From April to November, the park is used as a base for observing the dynamic discharge of the Miyagase Dam, and the "Ai-chan-go" road train, popular with children, runs from in front of the Park Center to below the dam. The "Craft Workshop Village" in the park is operated as a base for disseminating information on the traditional crafts of the local town of Aikawa to the rest of the prefecture and beyond, as well as a place to increase local interest and promote interaction between visitors and the community through creative experiences that allow visitors to come into contact with traditional crafts.
