If Kōichi Takaichi becomes the next prime minister of Japan, there are strong indications that she will appoint Shinjiro Koizumi as the Defence Minister. This decision is reportedly under serious consideration. Takaichi's strategic move could further strengthen her administration by leveraging Koizumi's popularity and political influence. The decision, if made, may occur in the coming days or weeks.

Cabinet reshuffles and appointments are significant events in Japanese politics. The selection of key roles, such as the Defence Minister, can indicate shifts in policy direction and political strategy. In this case, people are looking at Koizumi's moderate stance and appeal among younger demographics. These factors could bring diverse perspectives to the traditionally conservative defence stance.

In the US or EU, such a move would similarly be seen as a strategic decision. A popular and influential figure in a key role can consolidate support and effectively push forward the administration's policies. Particularly in defence, a moderate stance may be viewed positively by people hoping for less aggressive foreign policies.
