Chūbu region

The Chūbu region is a large and diverse area located in central Honshū, Japan's main island.

It serves as the widest part of Honshū. Geographically, it sits directly between the Kantō and Kansai regions. This central position makes it a vital link between the eastern and western centers of Japan's economy and culture. The region includes various landscapes, from the Pacific Ocean to the Sea of Japan. It is also home to the famous Mount Fuji.

The geography of Chūbu is defined by its rugged and mountainous terrain. The central part of the region is dominated by the Japanese Alps. These steep mountains act as a natural divider for the country. They separate the Pacific side from the Sea of Japan side. The Pacific side experiences sunny weather during the winter. In contrast, the Sea of Japan side is known for being snowy in winter. Most of the land is steep, except for specific areas like the Nōbi Plain and certain coastal zones.

To understand the region, it is helpful to look at its three main subregions. These are Tōkai, Kōshin'etsu, and Hokuriku. The Tōkai subregion borders the Pacific Ocean. It includes the prefectures of Aichi, Mie, Shizuoka, and southern Gifu. This area is a narrow corridor that has been critical for travel since the Tokugawa period. One of Japan's most important ancient roads, the Tōkaidō, ran through this corridor. Today, this path is used by super-express highways and high-speed shinkansen railroad lines.

Within Tōkai, the Chūkyō Metropolitan Area is a major economic force. This area centers on the city of Nagoya and includes parts of Aichi, Gifu, and Mie.

Nagoya is a major center for heavy industry, such as machinery and steel manufacturing. The region is also known for agriculture. Rolling hills in this area are used for growing tea and mandarin oranges. The Nōbi Plain has been used for growing rice since the seventh century. This subregion is a vital hub for both industry and food production.

The Kōshin'etsu subregion is often called the "roof of Japan" due to its high, rugged mountains. This area includes the Yamanashi, Nagano, and Niigata prefectures.

The population in this subregion lives mainly in six elevated basins. These basins are connected by narrow valleys. Historically, Kōshin'etsu was a major area for silk production. After World War II, silk output declined. However, the workforce moved into other manufacturing sectors. These include precision instruments, textiles, and food processing. This area shows how a region can adapt its industry over time.

Hokuriku is the third major subregion and sits along the Sea of Japan coastline. It includes Ishikawa, Fukui, and most of Niigata and Toyama. The climate here is quite different from the Tōkai side. Hokuriku experiences very heavy snowfall and strong winds during the winter. This snow can sometimes be thick enough to block major roads.

The region has turbulent rivers that provide abundant hydroelectric power. Hokuriku also has port facilities used for trade with China, Korea, and Russia. This connectivity helps support its extensive industrial development.

Demographically, Chūbu is a highly populated and growing region. As of June 1, 2019, the population was 23,010,276 when including Mie.

The three densest areas are the Chūkyō metropolitan area, the Niigata-Toyama area, and the Nagano mountain region. Nagoya is the largest city, with a population of 2,331,078. Other significant cities include Niigata, Shizuoka, and Kanazawa. For travel, the Chubu Centrair International Airport serves as the largest airport in the region. It is located south of Nagoya and provides many international and domestic connections.
