# 塗るタウン！ > The cities, towns, and villages you visit are automatically colored onto a map of Japan. This covers all 1892 cities, towns, and villages nationwide, and can be determined without an internet connection.

Places you visit on trips or drives are recorded on the map, allowing you to see at a glance "how far you've traveled in Japan."

■ 1,892 Cities, Towns, and Villages Nationwide
Designated cities are counted by ward. When wards are reorganized into cities, there are 1,741 cities, towns, and villages, matching the number of municipalities listed by the Ministry of Internal Affairs and Communications.

■ Fully Automatic Coloring
Simply open the app. There are no buttons. It records your location at regular intervals while driving and automatically colors in the cities, towns, and villages you've passed. You can choose the positioning interval from 15 seconds/30 seconds/60 seconds/120 seconds. To stop recording, select "Stop" in the notification or switch it in the settings screen.

■ No Communication Required
City, town, and village boundary data is stored within the app. Even without a network connection, it can determine "which city, town, or village you are currently in."

■ What you can see
- Coloring of the map of Japan (zoom in and out with pinch or +/- buttons, tap a city/town/village to see its name and first visit date)
- Display of whether recording is in progress (you can see at a glance when it's stopped)
- Completion rate by prefecture (including the number of prefectures completely visited)
- List of cities/towns/villages for each prefecture (tap to jump to that location on the map)
- History of colored locations
- Export to CSV

■ Records are stored only on the device
Visit records are saved only on the device. There is no app server. No ads or analytics are included.

■ About location information
We use Google Play Developer Services for positioning (because GPS alone cannot obtain location indoors or in urban areas). While "Automatically color" is enabled, a notification indicating that positioning is in progress will appear in the notification area. Disabling it will stop positioning.

■ Precautions
- If you pass through cities/towns/villages in a shorter time than the positioning interval while driving, some locations may be missed. Shortening the interval will reduce battery consumption.

* Boundaries have been simplified for display and determination purposes. Boundaries may sometimes be mistakenly identified as belonging to an adjacent municipality.

* The six villages in the Northern Territories and the seven "undetermined areas" that do not belong to any municipality are depicted on the map but are not included in the denominator of the achievement rate calculation.

| Is collection mandatory or optional? | **Optional** (It will not work without permission for location information, but permission itself is optional) |
