In brief

What Japan Meteorological Agency is

Full article ↗

The Japan Meteorological Agency (Japanese: 気象庁, Hepburn: Kishō-chō; JMA) is a division of the Ministry of Land, Infrastructure, Transport and Tourism dedicated to the scientific observation and research of natural phenomena. Headquartered in Minato, Tokyo, the agency collects data on meteorology, hydrology, seismology, volcanology, and other related fields.
The JMA is responsible for collecting and disseminating weather data and forecasts to the public, as well as providing specialized information for aviation and marine sectors. Additionally, the JMA issues warnings for volcanic eruptions and is integral to the nationwide Earthquake Early Warning (EEW) system. As one of the Regional Specialized Meteorological Centers designated by the World Meteorological Organization (WMO), the JMA also forecasts, names, and distributes warnings for tropical cyclones in the Northwestern Pacific region. This includes areas such as the Celebes Sea, the Sulu Sea, the South China Sea, the East China Sea, the Yellow Sea, the Sea of Japan, and the Sea of Okhotsk.

In context

How Japan Meteorological Agency compares

Counts over companies and vessels actually held in this directory — not over the world fleet, which is larger. Nothing here is estimated.

With 1 vessels attributed to it here, Japan Meteorological Agency is the 492nd largest of the 965 operators in this directory that hold at least one ship on record, against a median of 2 across that group. That is a count of individually identified hulls, not the company’s published fleet size — the two are different measurements and both are shown above where available.

Japan is the country of registration for 69 commercial operators in this directory, among which Japan Meteorological Agency ranks 22nd by ships on record. Between them those companies hold 153 vessels here. 2 of them carry a published container-capacity ranking. See every operator registered in Japan.

Founded in 1956, Japan Meteorological Agency is 70 years old. This directory holds 65 operators founded within five years either side of that date, whose median fleet on record is 1 ships. The median founding year across all commercial operators here is 1966, and the oldest on record dates to 1514.
