Route map

The Tōkaidō Main Line (東海道本線, Tōkaidō-honsen^?) is the busiest^{citation needed} trunk line of the Japan Railways Group (JR Group), connecting Tōkyō and Kōbe stations. It is 589.5 km (366 miles) long, not counting its many freight feeder lines around the major cities. The Tōkaidō Shinkansen runs largely parallel to the line.

The term "Tōkaidō Main Line" is largely a holdover from pre-Shinkansen days; now various portions of the line have different names which are officially used by JR East, JR Central, and JR West. Today, there are no passenger trains that operate over the entire length of the line (other than certain overnight services; see below), so longer intercity trips require several transfers along the way.

The Tōkaidō Main Line is owned and operated by three JR companies:

• East Japan Railway Company (JR East) (Tōkyō-Atami)
• Central Japan Railway Company (JR Central) (Atami-Maibara)
• West Japan Railway Company (JR West) (Maibara-Kōbe)

Station list

JR East

Tōkaidō Line shown in orange in this map of the southern approaches to Tōkyō

This section is operated by East Japan Railway Company (JR East).

The Tōkaidō Main Line in the Greater Tokyo Area is often referred to as Shōnan densha (湘南電車). It has rapid services called Rapid Acty (快速アクティー, Kaisoku akutī^?) and Commuter Rapid (通勤快速). It runs on dedicated tracks parallel to the Yamanote Line in central Tokyo, the Keihin-Tōhoku Line between Tokyo and Yokohama, and the Yokosuka Line between Tōkyō and Ōfuna. Some Shōnan-Shinjuku Line trains share the segment south of Yokohama to Ōfuna and Odawara.

The Tōhoku Jūkan Line, a JR East project, will extend the services of the Utsunomiya Line, the Takasaki Line, and the Jōban Line to Tokyo Station, connecting through to/from the Tōkaidō Line.¹

Almost all trains along this section of the line have "Green Cars" with forward-facing seats, which can be used after paying an additional fee.

• Shōnan Liner services are special, all-reserved commuter express trains with comfortable seating. They operate from Odawara to Tōkyō on weekday mornings, with a few services terminating in Shinagawa. Return services run from Tōkyō to Odawara on weekday evenings. Like commuter rapid trains, Shōnan Liner services normally make no stops between Shinagawa and Fujisawa. Between Fujisawa and Odawara, varying stops are made. In addition to the standard fare, a reserved seat fee of ¥500 is required to use the Shōnan Liner.
• Keihin-Tōhoku Line stations between Tōkyō and Yokohama officially are a part of the Tōkaidō Main Line. These stations are: Yūrakuchō, Hamamatsuchō, Tamachi, Ōimachi, Ōmori, Kamata, Tsurumi, Shin-Koyasu and Higashi-Kanagawa.
• Yokosuka Line stations between Tōkyō and Ōfuna officially are a part of the Tōkaidō Main Line. These stations are: Nishi-Ōi, Shin-Kawasaki, Hodogaya and Higashi-Totsuka. The route of the Yokosuka Line between Shinagawa and Tsurumi is separate from the main line and is referred to as the Hinkaku Line (品鶴線, -sen^?), on which Nishi-Ōi and Shin-Kawasaki stations are located.

JR Central

The Tōkaidō Line between Atami and Maibara is operated by JR Central, and covers the Tōkai region - Shizuoka Prefecture, Aichi Prefecture and Gifu Prefecture.

Branch lines

Both the Mino-Akasaka and Tarui branch lines separate from the Main Line at Minami-Arao junction (南荒尾信号場^?), located 3.1 km west of Ōgaki Station.

Mino-Akasaka Branch Line

Tarui Branch Line

Between Ōgaki and Sekigahara, there is a 25 per mil grade. In 1944, a single track bypass was built to avoid this steep slope of the main line and the old westbound track was removed. In 1946, a branch line was constructed on the site of the former westbound main line track; it is commonly referred to as the Tarui Line.^{citation needed} Presently, local trains use the Tarui Line track while express and freight trains use the bypass track when climbing the slope from Ōgaki to Sekigahara.

JR West

The western part of the Tōkaidō Main Line from Maibara to Kōbe is operated by JR West and forms the main trunk of the company's Urban Network in the Osaka-Kobe-Kyoto metropolitan area. Although the line is divided into three segments, known as the Biwako Line, JR Kyoto Line, and JR Kobe Line, they are part of a single contiguous network, with many services traversing multiple sections. The Biwako Line includes a segment of the Hokuriku Main Line. Some services on the Kosei, JR Takarazuka and Gakkentoshi lines run through onto the Tōkaidō Main Line.

Biwako Line

The section between Maibara and Kyoto is known as the Biwako Line. The line also includes the section of the Hokuriku Main Line between Maibara and Nagahama, where some Kyoto-bound trains originate.

JR Kyoto Line

The section between Kyoto and Ōsaka is known as the JR Kyoto Line. Trains from the Biwako and Kosei lines travel through onto the JR Kyoto Line and continue west towards the JR Kobe Line at Ōsaka.

JR Kobe Line

The westernmost section between Ōsaka and Kōbe is part of the JR Kobe Line, which continues west to Himeji on the San'yō Main Line. Although Kōbe is the official terminus of the Tōkaidō Main Line, most trains continue to Nishi-Akashi, Himeji and beyond.

In addition to standard local, rapid, and special rapid service trains, the Tōkaidō Main Line also hosts a number of limited express services.
