In brief

What Japan Coast Guard is

Full article ↗

The Japan Coast Guard (Japanese: 海上保安庁, Hepburn: Kaijō Hoan-chō) is the coast guard responsible for the protection of the coastline of Japan under the oversight of the Ministry of Land, Infrastructure, Transport and Tourism. It consists of about 13,700 personnel. The Japan Coast Guard was founded in 1948 as the Maritime Safety Agency and received its current English name in 2000.
The motto of the Japan Coast Guard is "Righteous Benevolence" (正義仁愛, Seigi Jin'ai).

How Japan Coast Guard compares

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

Japan is the country of registration for 69 commercial operators in this directory. 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 1948, Japan Coast Guard is 78 years old. This directory holds 78 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.
