Meteorological observations in Japan are carried out not only by Japan Meteorological Agency but also by Ministry of Land, Infrastructure, Transport and Tourism and Japan Coast Guard, Ministry of the Environment, prefectures, fire departments, etc. However, because of different observation purpose, the data release situation is different, and it became clear that cooperation among observation systems was not taken.
