Mountain Collector

Mountain Collector tracks your climbs across Japan's most iconic peaks. Build your personal summit collection by recording treks through multiple methods—upload GPX files from your favorite hiking apps, use GPS to log climbs in real time, or manually enter past expeditions through the calendar.

The app specializes in Japan's famous 100 mountains, showing detailed information about each peak and letting you explore the official list. As you climb, the app marks your progress on an interactive map and updates your personal records. You can review all logged treks, including the exact routes and areas you've traversed, straight from the Records menu.

Create custom collections beyond the standard 100-mountain list. Name your own themed sets—perhaps "Favorite autumn hikes" or "Best views in summer"—and attach climbing records to build a personalized mountain diary. Organize peaks by what matters to you, not just the canonical rankings.

Before heading out, access essential climbing resources directly from each mountain's page. The app bookmarks major weather forecasting sites, volcanic activity alerts, and the Yamareco hiking community platform, so you can research conditions and read trip reports without leaving the app.

Whether you're a casual hiker documenting occasional summits or a serious peak collector chasing completion, Mountain Collector makes it simple to log your progress and celebrate each accomplishment. Turn your trek history into a visual record of mountains conquered and memories made.
