The name Kōshin'etsu is a composite formed from the names of old provinces which are adjacent to each other — Kai (now Yamanashi), Shinano (now Nagano) and Echigo (now Niigata). The region is surrounded by the Sea of Japan to its north west, Hokuriku region to its west, Tōkai region to its south west, Kantō region to its south east, and Tōhoku region to its north east. The name for this geographic area is usually combined with Kantō region (as in "Kantō-Kōshin'etsu"); and it is sometimes combined with Hokuriku region (as in "Kantō-Kōshin'etsu-Hokuriku" or "Hokuriku-Kōshin'etsu").
