Japan Meteorological Agency

The Japan Meteorological Agency is a government meteorological office based in Tokyo, Japan. The facility coordinates its activities from a central building that houses administrative areas alongside analysis centers for earthquake monitoring and ocean observation.

The agency was founded in 1875 during the Meiji era to standardize meteorological observations and support maritime navigation with weather forecasts. In the 20th century, it gradually expanded its mandate to include seismic monitoring and tsunami early warning systems.

The meteorological office bears a name that emphasizes its scientific mission since the 19th century. The institution plays a central role in daily life across Japan, where people routinely check forecasts to plan travel and prepare for natural hazards.

The facility is not open for regular visitor tours, but provides real-time access to weather data, seismic information, and marine forecasts through its multilingual digital platforms. Mobile applications allow users to retrieve current warnings and historical climate data for different regions across Japan.

The office operates four specialized marine observatories that collect data from the Pacific Ocean and contribute to global climate research as well as typhoon tracking. These observatories often operate far from the Japanese coast and record changes in water temperature and current patterns that are crucial for long-term forecasting.
