The was a Japanese Shinkansen high-speed electric multiple unit which operated between 1985 and 2012 on the Tokaido Shinkansen and Sanyo Shinkansen high-speed lines. They were introduced after the 200 series trains, but their numbering is such because in the days of Japanese National Railways (JNR), Shinkansen types running east of Tokyo were given even numbers and those west of Tokyo odd numbers, hence they were given the next odd number in line after 0, 100. The last remaining examples of the type were withdrawn from service following the last runs on 16 March 2012.
Overview
As a full-scale redesign of the Tokaido-Sanyo Shinkansen, a total of 1,056 cars were manufactured and put into service between 1985 and 1992, consisting of 66 16-car sets. The train was the first to incorporate the double-decker cars used in Kintetsu Railway's Vista Cars and in railways in Europe and the United States, and was the first to be used in JNR and Shinkansen trains, leading to increased seating capacity and improved service, which helped promote the Shinkansen and improved its image. In terms of interior and technology, many of the equipment and technologies were later installed in Shinkansen trains produced thereafter.
The train capacity and manufacturing costs were set to be the same as those of the 0 Series, and the aim was to shorten travel times while minimising improvements to ground facilities. In addition, it was developed with the intention of being a "symbol of JNR reform," and the development goal was set to be "customers first, crew members second".
This model was the mainstay on the Tokaido and Sanyo Shinkansen lines from the end of the JNR era until the launch of JR, but with the introduction of successor vehicles, it was withdrawn from service on the Tokaido Shinkansen on 16 September 2003, and from service on the Sanyo Shinkansen on 16 March 2012.
Design
thumb|This style was called "shark nose"
They differed visibly from the earlier 0 series in that the nose profile was more pointed. Another less obvious difference with the 16-car sets was that not all the cars were powered; the driving cars on each end were unpowered, as were the two bi-level centre cars. Some later production sets had powered driving cars and four unpowered bi-level trailers in the middle instead. The bi-level trailer cars contained a combination of restaurant cars, and first class compartments, or open-plan first class seating and first class compartments, or open-plan first class seating and refreshment cars. The arrangement of the lights in the signal lights has been changed from two vertical lights in the 0-series to two horizontal lights, giving it a long, narrow shape. This design was proposed by Kinki Sharyo and adopted. When the front signal lights are on, they remain on, and when the rear signal lights are on, a red filter is automatically attached, making them appear to be on in red.
The external livery was white (White No. 3) and blue (Blue No. 20).
Following their removal from front-line service, 100 series sets were later reformed into shorter four- and six-car sets for the slower Kodama services on the Sanyo Shinkansen line. These four- and six-car trains did not have bi-level cars.
Variants
Pre-series unit
Originally numbered X0, the pre-series set X1 was delivered in 1985, with test running commencing from 27 March that year. The X1 set entered revenue service for passenger evaluation trials on the Hikari services from 1 October 1985.

16-car X sets

Following passenger evaluation trials with the pre-series set X1, a total of seven X sets were built for use on Tokaido and Sanyo Shinkansen Hikari services. The first four production units entered service from 13 June 1986 as 12-car sets without bilevel trailer cars, numbered G1 to G4, and were used on Tokaido Kodama services until October in the same year.

The first six-car K set (K51) was formed in January 2002 for use on Sanyo Shinkansen Kodama services from February 2002. These sets feature 2+2 abreast seating throughout, utilizing former Green class seats from withdrawn 100 series cars. Sets started appearing in the new JR-West Kodama livery from August 2002, with all ten sets (K51–K60) similarly treated by August 2004. The first set treated, K53, was returned to traffic on 14 July 2010.
These sets were withdrawn from service on 16 March 2012.
