It's funny... Standard (non-Shinkansen) JR East cars (East Japan Railway Company) are, and have always been, similar to these. For example, this is a "Yamanote Line" train set.
The Yamanote Line is actually a "Beltway" circular route all around Tokyo that travels in both directions.
This, is the "Chuo" line.... A rapid express line that goes through Tokyo, to and from the suburbs to the east/west (particularly Nagoya).
Most of the standard, every day JR East "non-shinkansen" trains will look something like this.
By the way, the latest version of the Shinkansen - the ALFA-X - released this past week... supposed to test at 400Kph and do standard service at 360Kph.
