The San'yō Shinkansen (Japanese: 山陽新幹線; lit.'Southern new main line') is a line of the Japanese Shinkansen high-speed rail network, connecting Shin-Osaka in Osaka with Hakata Station in Fukuoka, the two largest cities in western Japan. Operated by the West Japan Railway Company (JR West), it is a westward continuation of the Tōkaidō Shinkansen and also serves other major cities in between on Honshu and Kyushu islands such as Kobe, Himeji, Okayama, Hiroshima, and Kitakyushu, through the Shin-Kanmon Tunnel. The Kyushu Shinkansen continues south of Hakata to Kagoshima. The San'yō Shinkansen connects Hakata with Osaka in two and a half hours, with trains operating at a maximum speed of 300 km/h (186 mph) for most of the journey. Some Nozomi trains operate continuously on San'yō and Tōkaidō Shinkansen lines, connecting Tokyo and Hakata in five hours.
