The Yomiuri newspaper reported that Japan's expert panel is considering changes to its National Security Strategy to permit initial research into developing domestically built nuclear-powered submarines without committing to a full fleet acquisition. This move comes as regional tensions rise, with analysts noting increased security needs for Japan amid worsening regional rivalries. While the idea faces expected opposition within Japan, given it is the only country to have suffered nuclear attacks, there is acknowledgment of growing security concerns. Government sources suggest that if public support is strong enough, the project could receive official approval. The proposal aims to enhance Japan's maritime defense capabilities without making immediate commitments to acquiring a fleet.
