History
The 255 series was a limited express train type, specifically designed for services in Chiba Prefecture. Chiba is an adjacent prefecture to Tokyo with both dormitory suburbs and tourist spots (mostly beaches), so JR East decided to introduce brand new trains that could attract both commuters and tourists. The company also planned to replace 183 series, which had been used for more than 20 years.
The body design was based on 253 series, though the 255 series had no gangway at the front end. Each unit consisted of nine coaches including a Green Car (first class), and initially introduced to Limited Express View Sazanami (Tokyo - Tateyama via Uchibo Line) and View Wakashio (Tokyo - Awa-Kamogawa via Sotobo Line). JR East called these services View, showing that they were provided by the latest rolling stock. However, when the 183 series retired in 2005, the company removed the word.
Due to a drop in demand following motorway extensions, limited express services in Chiba Prefecture had been declining since the mid-2000s. As using nine-car trains was excessive, the number of trains provided by the 255 series gradually declined. All units were supposed to be withdrawn in 2024, but JR East decided to retain a unit for a while due to a train shortage despite completing farewell tours.
Current Operations & Future Prospects
A nine-car unit still remains active at Makuhari depot. It might be used for extra limited express services between Tokyo or Shinjuku and towns in Chiba Prefecture during high seasons, but it is unclear how long the unit lasts. Since the farewell tours have already been held in 2024, its retirement seems to be imminent.
