An animated film adaptation of a children's literature work. One day, a small, hairless stray dog appeared at Chojabaru, the trailhead of the Kuju Mountain Range, and quickly grew very attached to the people there. The locals treated its hair loss with hot spring therapy and named it "Heiji." Heiji grew up splendidly and, as a guide dog of Kuju, protected the lives of climbers for 14 years—through rain, wind, and snow—beloved by many, and closed its life without a single mountaineering accident. A heartwarming, moving story of humans and a guide dog!
