Three areas make up this part of Japan. The first is still known by the vague name of Kansai, meaning 'west of the barrier', referring to the 10th-century frontier with the neighbouring region of Kanto. It encompasses the historical and cultural centres of Nara and Kyoto, as well as the quintessentially modern city of Osaka and the resort area of Wakayama. The rest of mainland Honshu to the west (known as Chugoku) is of greatest interest along its coastlines, with historic Hagi on the rural north coast, and the crowded more urban southern shore, including the tragically famous city of Hiroshima and the scenic area of islands known as the Inland Sea. Shikoku, the third area and the one least known to visitors, boasts magnificent mountain scenery, several of the few remaining original castles in Japan, and the pilgrimage route known as the '88 Temple Circuit'.
