Kōfu in the context of Chūō Shinkansen
The Chūō Shinkansen (中央新幹線, Central Shinkansen, lit. 'Central new trunk line') is a Japanese maglev line under construction between Tokyo and Nagoya, with plans for extension to Osaka. Its initial section is between Shinagawa Station in Tokyo and Nagoya Station in Nagoya, with stations in Sagamihara, Kōfu, Iida and Nakatsugawa. Following the completion of the Tokyo–Nagoya line, the line will extend to stations in Mie, Nara and Osaka. The line is expected to connect Tokyo and Nagoya in 40 minutes, and eventually Tokyo and Osaka in 67 minutes, running at a maximum speed of 505 km/h (314 mph). About 90% of the 286-kilometer (178 mi) line to Nagoya will be tunnels.
The Chuo Shinkansen is the culmination of Japanese maglev development since the 1970s, a government-funded project initiated by Japan Airlines and the former Japanese National Railways (JNR). Central Japan Railway Company (JR Central) now operates the facilities and research. The line is intended to extend and incorporate the existing Yamanashi test track (see below). The trainsets are popularly known in Japan as linear motor car (リニアモーターカー, rinia mōtā kā), though there are many technical variations.
