高速道路料金マップ

This app calculates the tolls of expressways, urban expressways (capital expressways, etc.) and major toll roads in JAPAN. You can also calculate connections.
You can enter the departure point and destination one by voice, alphabetical order, and route, and the interchange name once searched is registered in the history, so you can easily call it.
You can also select an interchange from the map.
The regular charge and the discounted charge for using the ETC card are also displayed.
Depending on the departure date and time, the required time considering the traffic jam forecast is displayed.

* Interchanges on the map cannot be distinguished from half interchanges. This is most likely if the fare calculation does not find a route or if you see an unnatural roundabout route. In this case, selecting another interchange nearby should show the correct route.
