Tokyo Gas Co., Ltd. is a Japanese energy company founded in 1885 and headquartered in Tokyo, providing natural gas and electricity services.[1] The company’s current corporate symbol, introduced in 1985 to mark its 100th anniversary, is a geometric mark built from five squares.[2]

Design and History

Tokyo Gas adopted its current logo in 1985, when the company reached its 100th anniversary and introduced a new corporate identity system.[2] The mark consists of five squares arranged to form a stylized letter “T.”[3]

Before this redesign, the company used an older emblem featuring a star with the letter “G” for gas. The star referenced gas lights being celebrated as “a thousand stars.”[3]

Meaning and Symbolism

In the current five-square mark, the three squares forming the horizontal bar of the “T” represent “clothing,” “food,” and “housing.” The square forming the vertical stem represents “heart,” and the red square represents “future.” Together, the design expresses the company’s commitment to providing comfortable and enriched daily living through its gas business.[3]

Typography and Design

The Tokyo Gas wordmark is typically rendered in the Latin alphabet as “TOKYO GAS” when paired with the symbol mark in advertising and branding applications.[4] The geometric square-based construction of the symbol gives it a modular, grid-like appearance consistent with corporate identity systems of the mid-1980s.
