The former South Seas Mandate

Japan's relations with Oceania developed through strategic interests since the end of the 19th century.

Following the COVID-19 pandemic, Japan, having shifted its approach regarding security issues in Oceania, increased its involvement in the region's regional security programme.

Japan significantly increased its involvement in the region due to China expanding its presence "in terms of investment, assistance, and infrastructure projects".
