  "account": "Defense Minister Shinjiro Koizumi announced on Friday that Japan is considering the introduction of nuclear-powered submarines to its Self-Defense Forces. Koizumi assured that the public recognizes the necessity for a debate on the matter, stating that no decisions will be predetermined at this stage. Japan's three primary security documents are set to be revised by the end of the year, and there has been a proposal to include plans for assessing the acquisition of nuclear-powered submarines, which would pave the way for further research into the issue. Koizumi highlighted the advantages of nuclear-powered submarines, such as their extended submerged periods and increased operational speed, which would enhance mission safety. He also addressed concerns about the quietness of these submarines underwater, stating that the technology is improving. However, Koizumi acknowledged the significant challenges, including the substantially higher construction costs compared to conventional submarines and the need for specialized technical expertise in maintenance and servicing. He emphasized the government's commitment to conducting thorough discussions on the necessary measures to protect the lives and livelihoods of the Japanese people in the context of the evolving security environment.",
