More than 100 logos were submitted to Japan National Railways for consideration in the first round of judging. In addition to various ‘JR’ and ‘NR’ monograms, there was also a proposal to represent the rails of six of the passenger companies in symbolic form like British Rail, an iconic initial "R" for ‘Railway’, and an idea that focused on a numerical device, numbering each line.
On January 16th 1987, a final design was selected from two options. This was a simple design that combined the letters J and R to form a single continuous line in the same spirit as Canada National Railways. A ‘basic design that wasn’t gimmick’, something that Yamamoto stayed true to throughout his career, and was present in his winning design.
On the design of the JR logo Yamamoto suggested that trains move in both directions, rather than in one direction. Therefore, he designed the letters so that it would not feel strange seeing these move to the right or left.
To improve legibility and recognition at high speed–Japan had and continues to have one of the fastest rail services on the planet–the letters were made intentionally wider. The extended JP letterforms and their connection were also designed to give the viewer the impression of speed, even when static.
It is said that the JR logo designed by Yamamoto popularised the use of ‘J’ over ’N’, and led the way for many others such as JT – Japan Tabacco and The J League.
