JWA has released ” Weather Data API ”
It is 1km-mesh API, and enables up to 8 weeks prediction
Press Release2021.09.14

Japan Weather Association (JWA) is pleased to announce the availability of API for weather data in a format that is more accurate, finer and better suited to the development of analysis and forecasting services. The new API is more accessible than the previous APIs provided by JWA and to the current APIs on the market. The 1km-mesh size granularity and 8-week long forecasting make the data more useful for a wider range of business situations.

In the “eco×logi” project promoted by JWA, we have been working on addressing social challenges through product demand forecasting, food loss reduction, CPFR and other initiatives. With advancement of climate change and frequent erratic weather, it has increasingly become important for advanced service providers, data scientists and analysts to promote innovation by using highly accurate weather data to develop new services.
Through our commitment to developing such services, we are launching the new Weather Data API service to promote the vitalization of weather data utilization in API format.
