How indirect imperial action could remove Tojo

Japan's political conventions give Hirohito an indirect route to stopping the war without issuing a modern-style executive order. He could signal through trusted advisers or genro-like intermediaries that Tojo had misjudged the moment and no longer reflected the imperial wish. Cabinet rules required a serving officer to fill the Navy ministry, so the minister's resignation and the Navy's refusal to provide a replacement would collapse the government. The Navy's chain of command and its senior officers' loyalty to the emperor make that route credible even among men who supported southern expansion. Mitsumasa Yonai represents the kind of experienced, emperor-loyal figure who might replace Tojo as a safe pair of hands. Radical resistance or an attempted coup remains possible, but the mechanism lets Hirohito force a change while preserving the conventions surrounding imperial rule.
