YAMASTA to Hold the “Mt. Fuji Climbing Route 3776 Stamp Rally” with Fuji City, Shizuoka

Yama to Keikoku Co., Ltd., an Impress Group company operating media businesses in the mountain and nature fields, announced that its mountain stamp rally app YAMASTA will hold the “Mt. Fuji Climbing Route 3776 Stamp Rally” in cooperation with Fuji City, Shizuoka Prefecture, from May 15 to October 31, 2026. Mt. Fuji Climbing Route 3776 is a roughly 42-kilometer climbing route established by Fuji City, running from sea level to the 3,776-meter summit of Mt. Fuji. Participants start from either Fujinokuni Tagonoura Minato Park or Fujizuka and head toward the summit while experiencing the history of Mt. Fuji climbing and the rich natural environment at the foot of the mountain. Many climbers from across Japan, as well as international visitors, have challenged this route, which features the greatest elevation difference in Japan. During the campaign, users can check in with the YAMASTA app at eight designated points along Route 3776 to collect digital stamps designed around the scenery and history of each location. Depending on their progress, participants can receive commemorative can badges and a challenge completion certificate, and they can also enter a lottery for special pins. The commemorative badges are specially designed so that their patterns connect when collected and lined up. Participants who collect all stamps and complete the rally can receive a challenge completion certificate bearing their name and completion number, and may apply for a lottery to win special pins created in collaboration with the mountain souvenir brand Yamasanka. YAMASTA will also offer electronic coupons usable at shops and facilities around the Route 3776 course, which can be used for breaks during the climb or for activities before and after hiking. Check-ins at the Mt. Fuji summit are available only during the official climbing season, from July 10 to September 10. The organizer asks participants to refrain from climbing to the summit outside the open season. YAMASTA is a stamp rally app for exploring Japan’s mountains and natural sites. Users receive location-specific digital stamps by checking in at designated summits and landmarks. The app uses smartphone GPS and can be used even in mountain areas without mobile reception, with no need to queue at counters to receive stamps. As of May 14, 2026, YAMASTA offers 74 stamp rally events nationwide and has encouraged more than 1.13 million people to visit natural areas across Japan. In March 2025, it also launched “Yahoo Member,” a paid service designed to support more convenient mountain walking.
