Mitsubishi Heavy Industries Maritime Systems has officially delivered the JCG Goto (PL-205), the fifth Miyako-class large patrol vessel, to the Japan Coast Guard in Tamano, Okayama Prefecture. The handover marks another step in Japan’s ongoing efforts to expand and modernize its maritime security fleet. The Goto is part of a growing lineup of advanced patrol vessels designed to safeguard Japanese waters.
Once commissioned, the Goto will be assigned to the Nagasaki Coast Guard Office under the 7th Regional Coast Guard Headquarters. The ship will support a wide range of operations, including protecting territorial waters, conducting maritime rescue missions, maintaining public order, and securing marine resources. Its deployment strengthens Japan’s response capabilities across key strategic maritime zones.
The new vessel follows earlier deliveries from Mitsubishi’s Tamano plant, including the Miyako (PL-201), Osumi (PL-202), and Amami (PL-204). Another ship in the class, the Yaeyama (PL-203), was constructed by Japan Marine United Corporation at the Isogo facility in Yokohama. Mitsubishi also launched the sixth and seventh vessels—JCG Daito (PL-206) and JCG Hiroshima (PL-207)—earlier this year, both expected to join service after final outfitting between 2025 and 2026.
Japan plans to commission up to nine Miyako-class patrol vessels by 2028, as outlined in a 2024 coast guard supplementary budget. Each Miyako-class ship measures 117 meters in length, has a cargo capacity of 3,500 tons, and is powered by four Yanmar 8EY33W diesel engines delivering a combined 24,000 horsepower. Capable of speeds exceeding 25 knots, the class is believed to offer a longer range than its predecessor, the Shikishima-class, which can travel roughly 20,000 nautical miles.
