The TV anime Yuru Camp△ (ゆるキャン△), based on the manga by あfろ, is collaborating with Yahagi Dam (矢作ダム) — located across Toyoda City in Aichi Prefecture and Ena City in Gifu Prefecture — for a special stamp rally event beginning September 11, 2026.

Background

Yahagi Dam served as the real-world model for the dam that young Rin and her grandfather visit in Episode 1 of Yuru Camp△ SEASON 3. The stamp rally has been organized as part of the 55th anniversary commemorations of the dam’s completion, officially titled “矢作ダム完成55周年記念事業『ゆるキャン△』×矢作ダム スタンプラリー.”

How It Works

The event spans six areas across four municipalities in the Yahagi River basin: Toyoda City (Aichi), Ena City (Gifu), Neба Village, and Hiratayu Village (both in Nagano). Participants earn one stamp per purchase of ¥500 or more at participating shops, restaurants, and roadside stations. Collect eight stamps and exchange them for a limited-edition Dam Card at designated exchange points.

Each participating shop features a uniquely designed stamp depicting Rin or her grandfather, while the Dam Card itself showcases an illustration of young Rin and her grandfather. Only 3,000 Dam Cards will be distributed, on a first-come, first-served basis.
