Super View Odoriko

The Super View Odoriko (Japanese: スーパービュー踊り子) was the first deluxe version of the Odoriko operated from 28 April 1990 to 13 March 2020.[9][8] It used 251 series 10-car EMUs and runs between Tokyo or Ikebukuro and Izukyū-Shimoda.[4] The service was originally scheduled to commence from the start of the revised timetable on 10 March 1990, but rolling stock delivery delays meant that services were substituted by regular Odoriko services using 185 series EMUs.[9]

On weekdays, one train operated from Shinjuku to Izukyu-Shimoda, 2 trains operated back and forth between Tokyo and Izukyu-Shimoda, and one train operated from Izukyu-Shimoda to Ikebukuro each day.

On weekends, the Shinjuku-originating train changed originating station to Ikebukuro. Aside from that, services from Shinjuku to Izukyu-Shimoda and from Izukyu-Shimoda to Tokyo operated once a day. Moreover, during busy seasons, there were numerous extra services, with one extended service between Omiya and Izukyu-Shimoda, which ran along the Shonan-Shinjuku Line from Omiya to Yokohama; 2 trains from Tokyo to Izukyu-Shimoda, with only 1 returning to Tokyo; and one train from Izukyu-Shimoda to Shinjuku.

History

The limited express service was inaugurated on 1 October 1981 following the introduction of the then-new 185 series EMUs, replacing the earlier Amagi limited express and Izu express services from Tokyo to Izu.[12]

• 
  An Odoriko service in 1982 formed of a 183 series EMU
• 
  EF58 61 hauling the Limited Express Odoriko at Ofuna station

The Superview Odoriko operated from April 1990[13] until 13 March 2020. The Saphir Odoriko has been operating since 14 March 2020.[14]

Future development

This article needs to be updated. (October 2022)

Since the current rolling stock, the 185 series, is aging, there are plans to replace it.

The 185 series are beginning to be replaced by new E257-2000 series trains that used to operate Azusa and Kaiji limited express services on the Chuo Main Line, and were themselves replaced by E353 series trains. JR East plans to have all 185 series trains operating on the Odoriko service replaced by March 12 2021.[1]

JR East has also announced changes to the reserved seating on Odoriko services coinciding with the full retirement of 185 series EMUs from the service. Trains will now use LED seat reservation status indicators, rather than having dedicated non-reserved seat cars. This is the same system used by limited express services on the Chūō Line and Jōban Line. There will be two types of such supplementary tickets in the new system, namely the Reserved Seat Ticket (Japanese: 座席指定券, Japanese pronunciation: [Zaseki shitei ken]), and the Unreserved Seat Ticket (Japanese: 座席未指定券, Japanese pronunciation: [Zaseki mishitei ken]). The Unreserved Seat Ticket will replace Non-reserved Seat tickets (Japanese: 自由席券, Japanese pronunciation: [Jiyūseki ken]), which currently allow use of non-reserved cars.[15]

The Reserved Seat Ticket enables a specified seat to be reserved for the holder. The reserved status for the seat is signified by a green overhead lamp on top of the corresponding seat.

The Unreserved Seat Ticket enables the holder to be seated on any unreserved seat. A red overhead lamp signifies that the seat is unreserved; while a yellow overhead lamp signifies that the seat is reserved for the later part of the journey, implying that one has to give up their seat to the passenger who has reserved the seat, when they board the train later.

Additionally, Tōkaidō Shinkansen passengers currently receive a discount if they transfer to an Odoriko service. This will be discontinued in March 2021.

Namesake

The word odoriko means dancing girl in Japanese. The train service was named after the title of novel Izu no Odoriko (The Dancing Girl of Izu) by Yasunari Kawabata. The stage of the novel is the destination of the train, Izu Peninsula.

There are numerous services operating between Tokyo and the Izu Peninsula, which had all been discontinued and became the Odoriko limited express today.

• Amagi「あまぎ」, named after Mount Amagi, the mountain at the center of the Izu Peninsula.
• Ikoi「いこい」, derived from the Japanese verb "ikou" (憩う, いこう), which literally means to relax and rest (In this case, relax in the local onsens at Izu).

• Ideyu「いでゆ」, meaning hot springs, which are prominent at Izu.
• Okuizu「おくいず」, referring to the inner part (i.e. the southern part) of Izu.
• Olympia「オリンピア」, referring to the Olympic Games.
• Jukkoku「十国」, named after the Jukkoku Pass, a ridge between Atami and Kannami. The pass is called "Jukkoku" (literally: 10 provinces), because from there, 10 provinces can actually be viewed, namely Sagami, Musashi, Awa, Kazusa, Shimosa, Suruga, Totomi, Shinano, Kai and Izu Provinces.
• Shonan-Nikko「湘南日光」, as this former service links the Shonan region to Nikko.
• Joban-Izu「常磐伊豆」, as this former service links Izu to the Joban region (Japanese: 常磐地域), which refers to the combined region of the former Hitachi Province (Japanese: 常陸国) and the Iwaki Province (Japanese: 磐城国), to Izu.
• Tachibana「たちばな」, Japanese for mandarin oranges, which is a major agricultural product at Izu.
