Visiting multiple check-in locations set as a stamp rally serves as a motive to go out, and collecting all stamps provides a sense of accomplishment. Currently, 74 stamp rally events are held nationwide, with a cumulative total of over 1.13 million visitors. YAMASTA's check-in function for acquiring stamps uses the smartphone's location information system (GPS), so it can be used even in environments where mobile reception (calls) is offline. Additionally, since the app and server manage stamp rally events, the implementation period can be freely set. Participants can join at their convenience within the period and do not need to queue at a counter for stamp impressions, making it easy for anyone to enjoy. From March 2025, in addition to conventional functions, a paid subscription service "Yahho Kaiin" has been launched, which offers enhanced features and support to make mountaineering and hiking with YAMASTA even more convenient. **[Yama-to-Keikokusha Co., Ltd.]** https://www.yamakei.co.jp/ Established in 1930.
