Announcing the Establishment of Chikura-Westhill Cable Landing Station as Part of Disaster-Resistant Global Network

March 6,2014

In preparation against large-scale natural disasters and in order to enhance the business continuity of its communications services, KDDI will establish a new submarine cable landing station, Chikura-Westhill Cable Landing Station in Minamiboso City, Chiba Prefecture, to serve as a hub for international communications linking Japan with America and Asia.

Chikura-Westhill Cable Landing Station will be located some 28m above sea level, where it will not be affected by any tsunami that may be generated by a large-scale earthquake. Currently, the Chikura Cable Landing Station operates a number of high-capacity submarine fiber optic cables linking Japan with America and Asia, and plays an important role in supporting large-capacity data communications, including the Internet. However, in order to fortify the BCP [1] against large-scale earthquakes, the new station will be set up so as not be impacted by tsunami damage, and, in the event of such damage, will enable swift recovery of the network. In addition to playing its role as a base for the BCP, the new station will also operate networks to America and Asia in order to meet growing demand for Internet communications and to provide networks of higher-capacity and lower-latency, which are strongly demanded from financial institutions and other clients.

In addition to its submarine cables linking Japan with America and Asia, as part of its international communications network BCP, KDDI is working to ensure the continuity of international communications in times of disaster through the utilizing cable routes to Europe via Russia and satellite networks. KDDI will continue to strive to provide safe and secure communications services.。

Below is a brief overview of Chikura-Westhill Cable Landing Station.
