How Japan Plans to Turn Ageing Warships Into Leverage Against China

Japan is looking to turn ageing warships into a diplomatic asset. By transferring vessels to the Philippines and Indonesia, Tokyo could strengthen regional security ties while building leverage against China’s growing influence, observers say.

The transfers form part of a broader Japanese security assistance toolkit that includes equipment, training, maintenance and interoperability. The approach allows Tokyo to expand its regional influence without requiring partners to formally align against Beijing.

The Philippines expects to receive five Abukuma-class destroyer escorts within two to three years. Tokyo and Jakarta are also discussing the transfer of Asagiri-class destroyers. The first of those ships retired in March after 38 years of service.

An August 25 analysis by Japan’s National Institute for Defence Studies suggested that Tokyo could eventually expand the range of equipment available for transfer. Researcher Akinori Ishihara cited Japan’s transfer of ageing but operational warships to Russia during World War I, arguing that the key question is whether Japan can transfer equipment while retaining the defence capabilities it needs.
