DamApp

Search for dams from over 2,000 dams across Japan
-You can search for dams by name, distance from your current location, prefecture, type of dam, purpose of the dam, whether dam cards are distributed, etc.
- If you use check-in records and dam card possession information, you can search for dams that you have not visited or do not have a dam card for.
- Searched dams can be displayed in a list or on a map.

Select the dam you searched for and check the details of the dam
-You can refer to dam specifications such as address, levee height, water storage capacity, and dam card information.
- All dam information can be viewed offline (an internet connection is required only to display on the map).
- MAPCODE of dams and dam card distribution locations is included and can be transferred to NaviCon (NaviCon and MAPCODE are registered trademarks of DENSO Corporation).

Record the date and time of visit and dam card possession information
- Check in using location information and record the date and time of your visit. Once you have a dumb card, you can also record your possession information.
・You can add "favorite" or "want to go" labels or add notes. You can also search for dams by label or by the content of your notes.
- From the check-in records, you can refer to the visit achievement rate by prefecture, dam type, and purpose. Also the possession rate of dumb cards.

We collect and distribute as much information as possible about the distribution and version information of dumb cards, so you can download the latest information!

Also for those who have already visited many dams or have many dam cards and find it troublesome to record them one by one!
We also have a function to import visit records and dam card possession records from a text file, allowing you to save time by inputting them all at once.
