The NTT Group, aka Nippon Telegraph and Telephone Corporation, is one of the top information and communication companies in the world. Founded on August 1, 1952, by the Government of Japan, the company provides a wide range of services. These include mobile communications, telephone and data services, and internet services.
The history and evolution of the NTT logo reflect the modernisation of Japan’s telecommunications as well as the identity of the company as an innovator in technology and service. The iconic “Dynamic Loop”, which was first introduced in 1985, has become one of the most recognised corporate symbols in Japan. The article explores the evolution of the NTT logo over the years, among other details.
The Genesis of the NTT Logo (1952 – 1985)
The original NTT logo featured two interconnected “T” letters with thick horizontal bars enclosed in a loop to symbolise connectivity and national communication infrastructure. This minimalist emblem is designed in a turquoise green and white colour combination. The logo depicted the purpose of the company of uniting people worldwide through the connections of telegraph and telephone.

(1985 – 2025)
In 1985, NTT was spun off as a private company following a major reform and privatisation initiative. To mark the occasion an initiative was taken to build a comprehensive corporate identity. It sought to break with the past and position NTT as a forward-looking, customer-friendly organisation.
The famed dynamic loop logo was designed by Yūsaku Kamekura, in collaboration with PAOS (under Motoo Nakanishi). The designer explored over 150 concepts before settling on a form that was “simple and impressive”. Besides, it suggested the futuristic qualities of optical fibre. The dynamic loop emblem in blue consists of a bold, single curved line forming a spiral with a small loop at the top.
It expressed technological dynamism and the aspiration of the company to continually listen to customers and society. The brand name to the right of the emblem was written in black using the Lubalin Graph typography with thick pronounced serifs.

(2025 – Present)
To align with its increasingly global business and to mark its 40th anniversary as a private company, NTT refined its logo in 2025. It retained the iconic Dynamic Loop emblem but changed the typeface of the brand name “NTT” into a rounded custom designed one based on the NTT Data logo. The colour of the brand name was standardised from black to blue to symbolise unity and advanced technical capability.

The Elements of the NTT Logo
Font
The uppercase wordmark that forms a part of the NTT logo is rendered using a modern custom-designed geometric serif typeface. The typeface has similarities with Mortise X-Bold, Fantabular MVB Bold, and Sutro Shaded Fill.
Colour
The colour palette of the NTT logo is a combination of blue and white. Here, blue conveys trustworthiness and safety and aligns with the values of the company.
Finally
The evolution of the NTT logo is a rare example of strong visual continuity. It also showcases symbolic design and adaptive application. The logo iterations echo the transformation of the company from a state monopoly to a global leader in communications technology.
