Yamaguchi Yume Corridor Holds Second Round of Tour-Type Real Treasure Hunt!

To All Media Representatives

July, 2026 (a lucky month)

The Yamaguchi Central Region Cooperation City Area (common name: Yamaguchi Yume Corridor) will hold a tour-type real treasure hunt event, "Nanayume Adventure ~Crystal of Hope and the Story of Seven Towns~," starting on July 17, 2026 (Fri).

This event is a wide-area cooperation project that unfolds across six cities in Yamaguchi Prefecture (Yamaguchi City, Ube City, Hagi City, Hofu City, Mine City, Sanyo-Onoda City) and Tsuwano Town in Shimane Prefecture. Participants will use a distributed booklet and their smartphones to tackle a total of 95 quests set up within the area.

The first round, held last year, received over 34,000 cumulative reports and attracted many participants. This second round aims to promote local circulation and, through cooperation with tourist facilities, restaurants, and transportation, will be implemented as a project enjoyable for a wide range of generations, especially during the summer vacation period.

*Prizes can be applied for upon clearing a certain number of quests.
