The application provides various weather-related information published by the Japan Meteorological Agency, including weather forecasts and warnings. Users can customize the warning items through the app's settings. Additionally, the app offers images based on the Automated Meteorological Data Acquisition System of Japan (AMeDAS), as well as rain radar and river disaster protection information from the Ministry of Land, Infrastructure, Transport and Tourism of the Japanese government.

Some notable features of the app include the automatic saving of the latest viewed screen, the ability to view three days of weather forecasting information on a single screen for user convenience, and the display of all content in Japanese based on local Japan time. However, it is important to note that an internet connection is required to use the app, and the copyright of the displayed contents belongs to the respective publishing agencies or departments. Furthermore, the app retrieves information based on the local Asia/Tokyo time, so if the device's time is incorrect, the corresponding contents may not be displayed accurately.
