Japan's newly appointed Defense Minister, Koizumi, is starting to steer the ship with his strategic decisions and moves, asserting his presence swiftly since his inauguration. While it's premature to gauge the impact of his decisions, the stir he has created within the political and defense sectors is garnering attention. As Koizumi steps into this pivotal role on Japan's political stage, all eyes are on his next moves in shaping the country's defense strategies and military policies.

Koizumi's appointment and his early moves are of particular interest to the Japanese public given the sensitive nature of defense and military policies in Japan. The country has long maintained a "defense-only" policy as part of its post-WWII constitution, making any significant changes a matter of public interest and debate. It's also noteworthy that Koizumi is the son of a popular former prime minister, Junichiro Koizumi, adding extra spotlight to his actions.

Much like in the US or EU, the appointment and actions of Defense Ministers are highly scrutinized. Defense policies directly affect national security and foreign relations; hence public interest is always high. However, military changes can be more controversial and divisive in Japan due to its pacifist constitution, a contrast to the US and most EU countries with established and active military operations.
