The Tokyu Den-en-toshi Line (東急田園都市線 Tōkyū Den'entoshi-sen?) is a major commuter line operated by the private railway operator Tokyu Corporation and connecting south-western suburbs of Tokyo and neighbouring Kanagawa Prefecture, with its western terminus of Chūō-Rinkan, to a major railway junction of western downtown Tokyo, Shibuya. At Shibuya, nearly all the trains continue on the Tokyo Metro Hanzomon Line.
The line's color on maps and station guides is green, and stations carry the prefix "DT" followed by a number.
Nearly all trains on the Den-en-toshi Line are operated through to/from the Tokyo Metro Hanzomon Line using Tokyu, Tokyo Metro, and Tobu Railway 10-car EMUs. Around half of them continue beyond Oshiage, the terminus of the Hanzomon Line, to the Tobu Skytree Line (Kita-Koshigaya Station, Kita-Kasukabe Station and Tōbu-Dōbutsu-Kōen Station), Tobu Isesaki Line (Kuki Station), and Tōbu Nikkō Line (Minami-Kurihashi Station).
Tokyu operates two types of rapid services as well as Locals.
- Local (普通 Futsū?) (L)
- Stop at all stations. Eight service per hour per direction in day time.
- Semi-Express (準急 Junkyū?) (SE)
- Only up trains in weekday morning, to reduce congestion of passengers around Shibuya of rapid trains and to reduce delays with equalizing the speed of the trains.
- Express (急行 Kyūkō?) (Ex)
- Four trains per hour per direction in day time.
Through trains to Oimachi Line
A few trains are operated through to/from the Tokyu Oimachi Line to utilize forwardings to/from Saginuma depot, up to Ōimachi in the mornings, and down to Saginuma in the late evenings. These formations are 5-car sets, unlike the 10-car trains normally used on the line. A few express trains in holidays also serve from Chūō-Rinkan in the mornings, down in the evenings.

On March 6, 1907, the Tamagawa Electric Railway (玉川電気鉄道 Tamagawa Denki Tetsudō?, "Tamaden") opened the first section of the Tamagawa Line (玉川線?) tramway (not to be confused with today's Tokyu Tamagawa Line) between Shibuya and what is now Futako-Tamagawa, using 1,372 mm (4 ft 6 in) gauge. Two branch lines opened from the Tamagawa Line: the Kinuta Line (砧線?) (March 1, 1924) from Futako-Tamagawa to Kinuta, and the Setagaya Line (January 18, 1925) from Sangenjaya.
Tamaden was acquired by the Tokyo Yokohama Electric Railway (東京横浜電気鉄道 Tokyo Yokohama Denki Tetsudō?) (now Tokyu) on April 1, 1938. In addition to its principal Tokyo-Yokohama line, TYER also operated the Mizonokuchi Line (溝の口線?) from Futako-Tamagawa (called Futako-Tamagawa-en) to Mizonokuchi from July 15, 1927. The Tamagawa Line provided a further connection past Futako-Tamagawa to Shibuya. On July 1, 1943, following a request by the Japanese government, the line was regauged to 1,067 mm (3 ft 6 in) and integrated with the Ōimachi Line running from Ōimachi in southwest Tokyo to Futako-Tamagawa-en.
Tama Den-En-Toshi Plan
In 1953, Tokyu Group president Keita Gotō unveiled a "new town" planning scheme called the South-Western Area Development Plan. He envisioned new railway and freeway infrastructure (the latter being realized as the Tōmei Expressway) and large, clean houses for commuters working in Tokyo.
Development of the line
On May 11, 1969, the former Tamagawa Line and Kinuta Line were closed for the construction of a new underground Shin-Tamagawa Line along with the Route 3 of Shuto Expressway. Tokyu provided substitute bus service during the interim. The new line began service on April 7, 1977 between Shibuya and Futako-Tamagawaen (now called Futako-Tamagawa): through service with the Den-en-toshi Line began on November 16, 1977.
On August 12, 1979, the section from Ōimachi to Futako-Tamagawa was separated and named the Ōimachi Line again, thus restoring its original name and route. This coincided with the inauguration of through services from the Den-en-toshi Line via the Hanzōmon Line of the then Teito Rapid Transit Authority (帝都高速度交通営団 Teito Kōsokudo Kōtsū Eidan?, Eidan or TRTA) and the Shin-Tamagawa Line.
The line was completed in its present form on April 9, 1984, when sections between Tsukimino and Chūō-Rinkan were opened. The Shin-Tamagawa Line officially became part of the Den-en-toshi Line on August 6, 2000.
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 on June 2009, postponed from fiscal 2007. Ōimachi line trains, which are 5- or 6-car sets, will then run between Ōimachi and Mizonokuchi.
