Japan Phone Operators Report Poor Services After Earthquake

March 11 (Bloomberg) -- NTT DoCoMo Inc., KDDI Corp. and Softbank Corp., the three largest mobile-phone operators in Japan, said their services were disrupted across many regions after an earthquake shook buildings across the nation.

Wireless connections are poor across the country, Atsuko Suzuki, a spokeswoman for NTT DoCoMo said by phone. Phone services across Tohoku, Kanto and Tokai regions were bad, Softbank spokeswoman Makiko Ariyama said separately. Softbank is checking for possible damages to its telecommunications facilities, she said.

An 8.8-magnitude earthquake struck off the coast of northern Japan, shaking buildings violently in Tokyo, according to the U.S. Geological Service. A tsunami of more than 10 meters was reported in northern Japan.

The quake struck at 2:46 p.m. local time 130 kilometers (81 miles) off the coast of Sendai north of Tokyo, at a depth of 24 kilometers, USGS said. The Japan Meteorological Agency issued its highest tsunami warning for the country’s northeast coast.
