Sutanpo: Japanese Stamps

Collect Japanese eki-railway, tourist, and travel stamps on an interactive map, add photos, colors, and notes, and build a personal record of where you have been. Sutanpo is not limited to railway stamps – you can use it for any memorable place, from stations and viewpoints to castles, parks, shrines, and city spots.

Use the map to search places, assign stamps, lines, and locations, and instantly see which stamps you have already collected. Each location can hold multiple stamps and multiple lines, making it easy to organize real journeys, not just single stops.

Sutanpo is made for all kinds of explorers – tourists, families with kids looking for a fun way to discover places together, and local enthusiasts who enjoy collecting stamps and revisiting favorite spots.

And because stamp collecting is also about the look and feel of a real stamp in a paper journal, Sutanpo is designed to complement that experience, not replace it. You can add photos of your physical stamp book and real stamp impressions to create a clear digital overview of what you have already collected, see it all on the map, and easily revisit the places and memories behind each stamp.

Sutanpo also turns your travel history into a fun challenge. Complete themed quests, explore curated collections, track visited cities and prefectures, earn XP, unlock achievements, and compare progress with friends. Beautiful 3D rewards make collecting even more satisfying.
