With this app, you can eliminate the worry of "guerrilla rainstorms and thunderstorms" at once! The official app for the Sumida River Fireworks Festival.

In order to make your smartphone more useful, we have redesigned the UI of the app.

If you are a fan of fireworks, you can enjoy the show with this app. You can find the best places for viewing the show, and you can enjoy it from anywhere.

This app allows you to use the 3D display of the conventional radar, which is the world's most advanced "phased array weather radar".

The radar image allows you to know the location and the size of the rain clouds, which are the main cause of rain. It is useful for those who live in areas where there is no radar.

If you want to know about the weather, you can get the information for free.

In order to know the current weather, you can get the information from the Sumida River Fireworks Festival website.
