TheDen-en-toshi Line (田園都市線,Den'entoshi-sen; "Garden City Line") is a major commuter line operated by the private railway operatorTokyu Corporation and connecting south-western suburbs of Tokyo and neighboringKanagawa Prefecture, with its western terminus ofChūō-Rinkan, to a major railway junction of western downtown Tokyo,Shibuya. At Shibuya, nearly all the trains continue on theTokyo Metro Hanzomon Line. With a route length of 31.5 km (19.6 mi), it is the longest railway line operated by Tokyu Corporation.

The line's color on maps and station guides is green, and stations carry the prefix "DT" followed by a number.^[2]

On 6 March 1907, the Tamagawa Electric Railway (玉川電気鉄道,Tamagawa Denki Tetsudō; "Tamaden") opened the first section of aninterurban line between Shibuya and what is nowFutako-Tamagawa, using1,372 mm (4 ft 6 in) gauge.^[3] The line was called the Tamagawa Line (玉川線) and is not to be confused with today'sTokyu Tamagawa Line (東急多摩川線). The branch fromSangen-Jaya Station opened on 18 January 1925.

In 1953, Tokyu Group presidentKeita Gotō unveiled a "new town" planning scheme called theSouth-Western Area Development Plan. He envisioned new railway line and freeway and large, clean houses for commuters working in Tokyo.^[4] The railway line would become the Tama Den-En-Toshi Line and the expressway theTōmei Expressway. The parts of the new line completely overlaps the Tamagawa Line and the project is known as the Shin-Tamagawa Line or "New Tamagawa Line" which runs in an underground alignment under the old interurban line. The Tamagawa Line was closed in 1969 in anticipation for the opening of the Shin-Tamagawa Line, with the remaining branch line of the Tamagawa Electric Railway split off into the presentTokyu Setagaya Line. The underground Shin-Tamagawa Line opened a few years later in 1977, completely replacing the closed interurban line. Upon opening it was treated as a separate line from the Ōimachi Line connecting to said line at Futako-Tamagawa.^{[citation needed]}

In 2000, Tama Den-En-Toshi Line as depicted today was created by merging the Shin-Tamagawa Line and the section of the Ōimachi Line west ofFutako-Tamagawa.^{[citation needed]} Trains through servicing into theTokyo Metro Hanzōmon Line was extended beyondSuitengūmae intoIsesaki Line andNikkō Line ofTobu Railway on 19 March 2003.^[4]

Tokyu has expanded the line to four tracks from Futako-Tamagawa to Mizonokuchi; most trains of the Ōimachi line run through this section to Mizonokuchi, with some local trains making the intermediate stops. This service began in June 2009, postponed from fiscal 2007. Ōimachi line trains, which are 5- or 7-car sets, will then run betweenŌimachi and Mizonokuchi.^[5]

On 5 October 2025, around 11:00 p.m, the rear car of an out-of-serviceTokyu 5000 series (set 5101) was struck by an oncomingShibuya-boundTokyu 2020 series train (set 2035) as it was entering a layover track. The impact caused the out-of-service train to derail. It was hosting a trainee driver under instruction and had reportedly stopped slightly ahead of its designated position, leaving part of the train protruding onto the active track.^[6] The collision caused visible damages but no serious injuries were reported among the 149 passengers on board the moving train or among the crew on the stationary train.^[6] Following the collision, the operator disclosed that a "signal-setting error" had persisted for years since maintenance works were carried out in 2015.^[7] Following the collision, normal services on the Den-en-toshi Line were partially suspended for a few days, with nearby lines such as theŌimachi Line and theTokyo Metro Hanzōmon Line also experiencing service suspensions and disruptions. This was caused by the collided trains blocking the trains in train depot from exiting.^[8] Tokyu Railways deployed maintenance crews to remove the derailed 5000 series car and to inspect track and signal equipment nearKajigaya Station.^[9] To prevent similar accidents, Tokyu Railways inspected 33 other stations with similar track layout.^[8]

Nearly all trains on the Den-en-toshi Line are operated through to/from theTokyo Metro Hanzomon Line using Tokyu, Tokyo Metro, andTobu Railway 10-car EMUs. Around half of them continue beyondOshiage, the terminus of the Hanzomon Line, to theTobu Skytree Line (Kita-Koshigaya Station,Kita-Kasukabe Station andTōbu-Dōbutsu-Kōen Station),Tobu Isesaki Line (Kuki Station), andTōbu Nikkō Line (Minami-Kurihashi Station).^[10] At rush hour, an inbound train arrives as frequently as every 2 minutes 10 seconds.

The following three types of service are operated on the line.^[10]

  Local (各駅停車,Kakueki-teisha) (L)

Stops at all stations. Eight services per hour in each direction during the daytime. Two of eight are not through service to the Hanzōmon Line.

  Semi-Express (準急,Junkyū) (SE)

In the morning rush hour, all limited-stop services are semi-express.

In the daytime, two services are operated per hour in each direction and connect to a local train at Shibuya (outbound only), Saginuma and Nagatsuta (inbound only).

  Express (急行,Kyūkō) (Ex)

Not operated in morning rush hour. In the daytime, six services are operated per hour in each direction and two of six is through to the Ōimachi Line. Most express connect to a local train at Sangen-jaya (inbound only), Futako-tamagawa (outbound and through service to the Ōimachi Line), Saginuma and Nagatsuta.

On weekends, two seven-car express trains per days are operated to/fromŌimachi andNagatsuta. Also, a few trains are operated through to/from theTōkyū Ōimachi Line to utilize forwarding operations to/from Saginuma depot, up to Ōimachi in the mornings, and down toSaginuma in the late evenings. These formations are 7-car sets, unlike the 10-car trains normally used on the line. A few express trains during the holidays also serve fromChūō-Rinkan in the mornings, down in the evenings.^{[citation needed]}
