Japan has ratified a massive supplementary budget of 18.3 trillion yen for fiscal year 25, signifying considerable emphasis on bolstering its economy. The bulk of the amended budget appears to focus on economic enhancement through infrastructure projects and other active fiscal policy measures. The announcement, however, has sparked debates due to its hefty size.

In Japan, supplementary budgets often include a boost for public institutions and government-related projects. They are usually established to stimulate economic performance and stability. The large scale of this budget indicates the government's aggressive approach in tackling economic challenges and implies significant injections into various aspects of Japanese society.

Similar to Japan, the US and EU often use revised budgets as tools to stimulate their economies, particularly during slow growth periods or crises. However, the size and allocation of the supplementary budget may vary based on the specific economic challenges they face.
