+20Kyushu is the third largest and most southwesterly of Japan's four main islands. It is located southwest of Honshu, the main island, and is separated from it by the Kanmon Straits. The island is a distinct geographical and cultural region, comprising seven prefectures. It is notable for its active volcanoes, numerous hot springs, and significant historical role as the gateway for early continental influence into Japan, including the introduction of rice cultivation and Buddhism.
Kyushu is an island of volcanic origin, formed over millions of years. Its key features include major mountain ranges, large calderas like Aso, and extensive coastlines. While the entire island is not a single protected entity, it contains multiple national parks, quasi-national parks, and UNESCO Global Geoparks that protect its unique landscapes. The island's current purpose is as a major economic and population center for southwestern Japan, hosting key industries and a significant portion of the country's agriculture.
Kyushu is highly accessible. It is connected to Honshu by road and rail via tunnels and bridges, most notably the Kanmon Bridge and the Kanmon Tunnel. The island is served by multiple international and domestic airports, including Fukuoka Airport, which is a major hub. The Kyushu Shinkansen line provides high-speed rail service from the north to the south of the island. A comprehensive network of highways, national roads, and railways connects all major cities and towns. Tourist infrastructure is highly developed, with information centers, well-maintained roads, and public transportation available throughout the region. Access is generally not seasonally limited, though some mountain roads may close in winter.
The climate of Kyushu ranges from humid subtropical in the north and central regions to almost tropical in the south. The landscape is dominated by mountains and volcanoes, including the active Mt. Aso, one of the world's largest calderas. Vegetation is lush and diverse, featuring extensive cedar forests and subtropical plants in the south. The island's coastline varies from rugged cliffs to sandy beaches. While human influence is significant in urban and agricultural areas, large tracts of land remain well-preserved within its national and quasi-national parks.
Kyushu has played a pivotal role in Japanese history. It was the initial point of contact for cultural and technological exchanges with the Asian mainland, particularly China and Korea, from around the 4th century. The port city of Hakata was a major hub for trade and diplomacy. It was also the site of the Mongol invasions of Japan in the 13th century. In the 16th century, the first European traders and missionaries, such as the Portuguese and Francis Xavier, arrived in Japan via Kyushu. The island was a major center for the coal industry during Japan's modernization and was a crucial base for the Imperial Japanese Navy during the Pacific War.
