The Kansai Main Line (関西本線, Kansai-honsen, also called the "Kansai Line") is a railway line in Japan, which connects Nagoya Station with JR Namba Station in Osaka. It is jointly run by the Central Japan Railway Company (JR Central) and West Japan Railway Company (JR West), with the boundary between both companies being located at Kameyama Station in Kameyama, Mie.


The section from Kamo Station west to JR Namba Station is electrified and a part of the JR West "Urban Network", and is nicknamed the Yamatoji Line. The JR Central section from Nagoya to Kameyama is also electrified.

Despite its name, for much of its length it is a very local line with mainly single track sections and no regular express services. The line was originally built in the 1890s by Kansai Railway (later under the Japanese Government Railways and Japanese National Railways) as an alternate route from south Osaka to Nara and Nagoya, but competition from the Kintetsu lines and declining ridership forced the line to operationally become two electric suburban lines for Osaka and Nagoya respectively, with a less-used unelectrified rural section in the middle.

Formerly a Kasuga express train ran from Nagoya to Nara, but this service was discontinued in March 2006.


The Osaka Railway Co. opened the Minatomachi (now JR Namba) to Nara section between 1889 and 1892. The company merged with the Kansai Railway Co. in 1900.

The Nara Railway Co. opened the Nara to Kizu section in 1896. It merged with the Kansai Railway Co. in 1905.

The Kansai Railway Co. opened the Nagoya to Kizu section between 1890 and 1897, completing the line. The company was nationalised in 1907.


The Minatomachi to Tennoji section was duplicated in 1903 and extended to Kashiwara in 1908. The Nara to Kizu section was duplicated in 1914, and the Kashiwara to Nara section between 1923 and 1926. In 1944 the Oji to Nara section was returned to single track and the materials recycled for the Japanese war effort. The section was re-duplicated in 1961.

The Tomita to Kuwana section (except for the bridge over the Inabe River) was duplicated in 1973, and the Kuwana to Yatomi section between 1977 and 1980. The Yokkaichi to Tomidahama section was duplicated in 1993.


The Minatomachi to Nara section was electrified in 1973, extended to Kizu in 1984, and to Kamo in 1988.

The Nagoya - Hatta section was electrified in 1979, and extended to Kameyama in 1982.

Other matters of note

CTC signalling was commissioned between Kizu and Kameyama in 1983, and extended to Nagoya in 2001.

Freight services ceased in 1987, and in 1994 Minatomachi Station was renamed JR Namba to coincide with the opening of the Kansai Airport Line to Kansai Airport. In 1996 Namba Station and the approach line were relocated underground to eliminate a number of level crossings. There are plans to extend the line from Namba to Osaka Station, with construction to begin within the next few years. (See Naniwasuji Line for information.)
