If Japan was interested in seizing oil fields what islands might they invade?

If Japan were interested in seizing oil fields, it might consider the Kuril Islands, which are disputed with Russia and are geologically significant. Additionally, the Senkaku Islands, claimed by both Japan and China, are located near potential oil reserves in the East China Sea. While Japan currently has a pacifist constitution and focuses on diplomatic solutions, these areas could be of strategic interest due to their proximity to underwater energy resources.
