Prefectures
Japan has 47 prefectures, each of which has an elected governor and assembly. The prefectures are responsible for a wide range of local services, including education, healthcare, and public infrastructure. They also cooperate on regional issues and play a role in national politics.
States in the United States
The United States is a federal republic, meaning that it is composed of a number of semi-autonomous states. Each state has its own constitution, government, and laws. The federal government has limited powers that are specifically enumerated in the Constitution. All other powers are reserved to the states.
Comparison
Although prefectures and states are both subnational entities within their respective countries, they have different levels of autonomy and responsibility. Prefectures in Japan are more closely integrated into the national government than states in the United States. This is due in part to Japan's history of centralized governance, which dates back to the Meiji Restoration in the 19th century.
