Pacific Crossing, 
Pacific Crossing’s 21,000km fiber optic system consists of four fiber-pairs organized in four segments connecting four cable landing stations at Harbour Pointe, Washington (near Seattle); Grover Beach, California (between San Francisco and Los Angeles); Ajigaura, Japan (near Tokyo); and Shima, Japan (near Osaka and Nagoya). The network offers extensive backhaul into major U.S. and Japanese cities.
There are at least 20 other fiber cables serving Japan, so most international traffic can be re-routed.http://www.pc1.com
