Global Weather Data
Services

JWA provides global weather data ‘Weather Data API Global’ for any location in the world via API.

Compared to other countries in the world, Japan has four distinct seasons with significant annual and daily temperature variations*. Furthermore, being surrounded by the ocean, Japan receives substantial precipitation. This geographical location makes the country prone to damage from typhoons and heavy rains. To minimize these risks, Japan has developed weather observation technology. JWA has continuously refined/upgraded its forecasting technology since its establishment in 1950.

* Annual temperature variations: Difference between annual maximum and minimum temperature values.
Daily temperature variations: Difference between the highest and lowest temperature values during the day.

JWA compiles global weather data and forecasts from overseas meteorological agencies. Leveraging our highly advanced technologies, JWA creates models and forecasting algorithms tailored to diverse climates of various regions and hence provides weather forecast data for all regions across the world through ‘Weather Data API Global’.

‘Weather Data API Global’ allows one to continuously and comprehensively obtain various weather related data such as weather, temperature, and precipitation for any point in 196 countries across the globe, including 120-hour (5-day) forecasts and long-term forecasts for the next 8 weeks.

Long-term temperature changes due to climate change are already having a significant impact on the lives of people around the world. It has therefore become essential to consider weather disasters and risks in supply chain management of corporate activities.

By using highly reliable weather forecast data, it is possible to accurately predict the effects of large typhoons and changes in people’s behavior due to sudden changes in temperature. The JWA’s weather data will help people’s daily lives more comfortable and update the way weather data is used in business.
