How Many Prefectures In Japan?

If you have ever planned to visit Japan, or have ever heard the words prefecture and ward mentioned in Japanese film and anime, there’s a good chance you have wondered what these mean.

How Many Prefectures In Japan?

Not every country uses prefectures and wards to designate certain areas, so it is also pretty common to not have an idea about what these are.

So, what’s the deal with prefectures in Japan? How many prefectures are there in Japan? And how big is a prefecture?

In this simple guide, we explain what prefectures are in Japan, the difference between prefectures and cities, and what wards are.

Simply read on for all the answers.

What Are Prefectures?

Put simply, prefectures in Japan are districts. These prefectures subdivide Japan, and are further subdivided into municipalities.

Tokyo, the capital of Japan, is one of Japan’s many prefectures. Other famous locations in Japan that are prefectures include Chiba, Hiroshima, Kagawa, Kanagawa, Kyoto, Nagasaki, Okinawa, and Osaka.

Each prefecture in Japan has an elected governor. Ultimately, just like any country, subdividing the country into prefectures helps to govern each area on a more regional level.

Japan was divided into prefectures in the 1800s, during what is known as Japan’s Meiji period.

Are Prefectures In Japan Like States?

In terms of how Japan is geographically subdivided, prefectures are much like the fifty states of America. American states are divided into counties, which can be likened to the municipalities of Japan.

Despite this, Japan’s prefectures are not individually governed in the same way as states are governed in America. American states have their own laws, known as state law, despite these being close to federal law. Japan, however, is a unitary state.
