The Japan Information Highway (JIH) submarine cable is a high-capacity fiber optic cable system that connects Japan with the United States. The cable stretches approximately 21,000 kilometers and provides high-speed data transmission between Japan and the United States.
The JIH submarine cable system was launched in 1991 and was upgraded in 2000 to increase its capacity. The cable is jointly owned by NTT Communications, AT&T, Verizon, and SoftBank.
The JIH submarine cable system has become a vital part of Japan's telecommunications infrastructure, serving as one of the main routes for international data transmission. It provides reliable and high-speed connectivity to businesses, governments, and individuals in Japan and the United States.
The JIH submarine cable system has also played a crucial role in facilitating disaster relief efforts in Japan. In the wake of the 2011 earthquake and tsunami, the cable system quickly restored communications infrastructure, enabling affected regions to access critical information and support.
Overall, the Japan Information Highway (JIH) submarine cable system has been a significant contributor to the growth and development of Japan's telecommunications industry, providing reliable and high-speed connectivity to millions of users.
