Japan Offline Hiking Maps

Save hiking maps before you go, then use them offline to check your GPS location, planned routes, and checkpoints when mobile service is weak. Includes Mt. Fuji routes.

Japan Offline Hiking Maps helps you save Japanese hiking maps in advance and check your GPS location, saved maps, checkpoints, and planned routes when mobile signal is weak. While online, you can also overlay the Japan Meteorological Agency's rain cloud movement on the map.

The app displays Geospatial Information Authority of Japan map data with MapLibre. Save only the map areas you need, then confirm the saved map outline, your current location, and your checkpoints on the map.

Main features:

• Map zoom, current location, and north-up control
• Standard, pale, blank, and vertical-label map styles
• Jump to preset Japan 100 Famous Mountains locations
• Mountain name search to move to map locations
• Mt. Fuji Yoshida, Subashiri, Gotemba, and Fujinomiya planned routes
• Planned routes for selected Japan 100 Famous Mountains
• Create, copy, and edit planned routes
• Record a GPS route after the user starts recording, including while the app is in the background
• Create planned routes and checkpoints in the online Web planner, then add them to the app as GPX
• Highlight hiking trails and connecting footpaths
• Overlay JMA rain cloud movement on the map while online
• Follow-current-location mode
• Save selected map areas for offline use
• Saved map outlines on the map
• Add, rename, delete, and attach photos to checkpoints
• Capture a photo checkpoint from the map camera control
• Backup and restore checkpoints and saved map information
• Import GPX files and export a selected route and checkpoints as GPX

The free version supports up to 5 saved maps, 10 checkpoints, and 1 saved route in total. Offline Map Japan Pro is a one-time unlock that expands these limits to 50 saved maps, 500 checkpoints, and 100 saved routes. The route limit includes planned routes, GPS recordings, and routes imported from GPX. Pro also adds manual organization for saved maps and checkpoints, plus checkpoint category, color, and note editing and category/note search.

This app is not an official Geospatial Information Authority of Japan or Japan Meteorological Agency app. Map, GPS, and rain cloud display are support tools for checking location and map context. The rain cloud overlay does not judge hiking safety or trail availability. Always make decisions using local conditions, signs, official information, and multiple information sources.
