Origin of the Prefectural Name

Before, there were several ways to write the name of "Kanagawa" in kanji (Chinese characters). "Kanagawa" referred to the area of Kuraki-gun (county), Musashi-no-kuni (present Kanagawa-ku, Yokohama City). The area had been the important point for land and marine transportation from the olden times. The Shogunate Government of Edo concluded the "Kanagawa Treaty" (the Treaty of Peace and Amity) with Commodore Perry of U.S. in 1854, and established "Kanagawa Bugyo-sho" (Office of Kanagawa Commissioner) in 1859. And thus, Kanagawa became the name of the new administrative unit of prefecture in September 1868.

The prefecture can be divided into roughly three regions by topographic features; the mountainous region in the west, the plain and plateau in the central part, and the hilly and coastal area in the east.

1,500-meter high mountains of the Hakone and Tanzawa ranges are called "the roof of Kanagawa." The Sagami River which runs through the central part and the Sakawa River which runs through the western part are highly utilized as the important water resources. Lake Ashino-ko is located on the high altitude, ranked seventh among the major lakes in Japan. One of the characteristics of Kanagawa's lakes is that the manmade lakes of Lake Sagami-ko, Lake Tsukui-ko, Lake Tanzawa-ko and Lake Miyagase-ko were created for the water resources. The 426 km long coastline shows colorful and varied scenery, and the Keihin Industrial Zone along the Tokyo Bay has highly sophisticated ports.

There are also Hakone and Yugawara hot spring resorts which constitute parts of the Fuji-Hakone-Izu National Park, as well as Tanzawa-Oyama Quasi National Park and our prefectural natural parks. The "ancient city" of Kamakura, which is comparable to Kyoto and Nara, has many historic sites and scenic spots. Thus, Kanagawa Prefecture is not only the industrial and cultural center, but also a region blessed with rich natural environment and tourist attractions.


With the Tanzawa and Hakone mountain ranges in its north-western hinterland, Kanagawa Prefecture has the plain to the east and south, facing the Pacific Ocean. Because it is also affected by the Black Currents (warm currents) of the Pacific Ocean, it has a mild climate with high precipitation which is typical of the region along the Pacific Ocean.
