The Japan Ground Self-Defense Force bought 54 transporter erector launchers, each carrying six Type 88 missiles, for use as coastal batteries. With a range of 180 km, high subsonic speed and 225 kg warhead, it is similar to the US Harpoon missile. In 2015, an upgrade of the Type 88 became operational called the Type 12. The Type 12 features INS with mid-course GPS guidance and better precision due to enhanced TERCOM and target discrimination capabilities. The weapon is networked, where initial and mid-course targeting can be provided by other platforms, and also boasts shorter reload times, reduced lifecycle costs, and a range of 200 km. During the Balikatan annual military exercise on May 6, 2026, the Japan Ground Self-Defense Force launched two Type-88 anti-ship missiles from the Philippines at the decommissioned 890-ton Philippine Navy ship BRP Quezon. While the first missile hit and contributed to sinking the vessel, video indicates the second missile missed by a few meters, passing the target without a hit. The target was located around 75 km off the coast of Paoay in the northern Philippines, and the missiles reached the BRP Quezon within six minutes of the launch. On 1 June 2026, it was reported that the Philippines was considering acquiring the Type 88.

• Illustration — Radar vehicle (JTPS-P15) The basic launching vehicle configuration comprises a 6×6 Type 74 tactical truck with a maximum of six missile pods. The battery of type 88 includes four launch/transporters, a single target search radar, a single missile control station, four reloaders, and a digital communications station. The missile system takes about 45 minutes to transition from a camping or traveling position to combat-ready status. The missiles can be launched in two-second intervals. Usually, the SSM-1 is launched from within 100 km of the target.
