The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.

Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need.

[1] The site in Japan is the corporate building of KDDI (the successor of Kokusai Denshin Denwa Co., Ltd., Japanese party of TPC-1 System).

[2] The site in Hawaii is the corporate building of Hawaiian Telcom (the successor of Hawaiian Telephone Company, Hawaiian party of TPC-1 System).

Are the original buildings extant?

[1] The original building of "Ninomiya Cable Landign Station" still exists, but is no longer used (as of January 2014), and will be removed in the near future. Therefore, the plaque is to be placed at the building of KDDI Headquarter.

[2] The original building in Hawaii no longer exists.

Details of the plaque mounting:

[1] The plaque is to be placed where the visitors can access.

[2] The plaque is to be placed where the visitors can access.

How is the site protected/secured, and in what ways is it accessible to the public?

[1] The plaque site is within KDDI Headquarter, and is under the propoer security control. The visitors can access with prior appointment to KDDI (International Network Department, +81 3 6678 0800).

[2] The plaque is within HT Headquarter, and is under the proper security control. The visitors can access at the normal business hour.

Who is the present owner of the site(s)?

[1] KDDI Corporation (KDDI)

[2] Hawaiian Telcom (HT)

What is the historical significance of the work (its technological, scientific, or social importance)?

"TPC-1 System" was the first submarine telephone cables connecting the North America and Asia with the length of longer than 10,000km in total. TPC-1 System started its operation on 19th June 1964 with the congratulatory speeches of the President Lyndon B Johnson of USA and the Prime Minister Hayato Ikeda of Japan as the important national project of USA and Japan. It has contributed to the closer relationship and to the mutual development in culture and economy between USA and Japan. It also triggered the rapid development of the submarine telephone cable network in Eastern Asia, providing a big communication capacity between Eastern Asia and USA/Europe. TPC-1 System was the US$83Million project, which was jointly constructed by AT&T, HTC and KDD, by applying the state of the art technology "SD cable system", which was developed by the Bell Laboratory of AT&T, following SA & SB systems. A newly established Japanese company “OCC” also manufactured some portions of submarine cables under AT&T’s supervision. "TPC-1 Systems" were composed of three segments; 1) TPC-1 connecting Japan with Hawaii via Guam, Midway and Wake, 2) HAW-1 and HAW-2 connecting Hawaii and the main land USA and 3) Guam-Philippine Cable, the branch of TPC-1. TPC-1 Systems were cross connected at Hawaii with COMPAC, the British Commonwealth cable linking Canada, New Zeeland and Australia. TPC-1 Systems and COMPAC formed the Pan Pacific coaxial submarine cable network. TPC-1 Systems started its operation in June, 1964, and were completed in December, 1964 by joining of Guam-Philippine Cable. Since then, TPC-1 Systems were in operation more than a quarter century and will have 50 years anniversary in 2014. The quality of telephone circuit of the longest multi links through TPC-1 Systems, land cables in North American Continent and submarine cables in Atlantic Ocean was proven to satisfy the CCITT recommendation as the first time. The technology developed in SD cable system covers the dynamics of the cable in the sea, the machinery on board a cable ship and methodology of cable lay and repair, which became de facto standard of the cable lay and repair methodology. The technology developed in TPC-1 Systems has become the foundation of the construction and maintenance for the current fiber optic submarine cables used for international telecommunication today.

What obstacles (technical, political, geographic) needed to be overcome?

The extremely high reliability was necessary for the repeater especially for the vacuum electron tube in it, which amplifies the transmission signal in tandem. The requirement of high reliability was achieved by means of the quality control developed by Bell Laboratory and has been proved in long operation of TPC-1 Systems. The quality control methodology used in SD cable system was succeeded to current fiber optic submarine cable systems. TPC-1 was necessary to cross the Mariana trench and to be laid on complicated feature of the sea floor along the trenches. Scientists on ocean floor of USA and Japan jointly examined the hydrographic survey data obtained by Japanese Oceanography Service and determined the safe and stable cable route in the region. The knowledge established through coordination between the academic field and the business field has contributed to the planning of the following trans-ocean submarine cable projects.

What features set this work apart from similar achievements?

In order to satisfy the need for the stable telephone communication between Eastern Asia and USA/Europe in establishing a new world order after the second world war, USA and Japan agreed to construct TPC-1 Systems as the national project for both countries and, AT&T, HTC and KDD signed the "TPC-1 Construction and Maintenance Agreement" in February 1962. After the completion of the construction, the telephone traffic through TPC-1 Systems grew more than 50 percent every year, which showed the big contribution of TPC-1 Systems to the social and economic activities between Asia and USA/Europe. The telecommunication development in quality and quantity introduced by TPC-1 Systems, together with the development in transportation, drastically enhanced the inter-continents activities in community exchange and import/export. This drastic increase showed the potential huge growth in telecommunication traffic between Eastern Asia and USA/Europe and accelerated the construction of the submarine cable networks in East Asia and South East Asia (such as JASC, China-Japan, Korea-Japan, Taiwan-Okinawa, OLUHO, ASEAN cables with the total lengths more than 10,000km), which subsequently contributed in harmonizing Eastern Asia and USA/Europe. AT&T, HT and KDD enhanced coordination in implementation of TPC-1 Systems. For example, the considerably large part of the SD cable, made by OCC, and some telecommunication facilities, such as channel banks, echo suppressor, international telephone exchange switch for TPC-1 System were developed and manufactured in Japan under the co-supervision of AT&T and KDD.
