For Instagram, save an image and select it in the app. Available sharing apps depend on your device.
Every town you meet stays here. Place it to earn a stamp.
Silhouette uses the largest land area. Islands and holes may be omitted. Not for navigation.
Original synthesized soundtrack. Sound begins only after interaction. System reduced-motion preferences are respected.
Boundaries reflect the source date, not a live map. Unsettled boundaries follow the source. Designated-city wards are merged into their city; Tokyo's special wards remain separate. Sizes are normalized; the largest land component is simplified and holes are omitted.
