TOKYO - Five small tsunamis hit northern Japan late Wednesday, estimated at no larger than 16 inches high, Japan's Meteorological Agency said.
The first wave hit Nemuro port in Japan's northernmost island of Hokkaido at 9:29 p.m. and registered at 16 inches, smaller than the 6 1/2 feet tall or higher initially expected by the agency.
A few minutes later, a second wave of 8 inches hit the nearby port city of Kushiro to the southwest, the agency said.
Live water footage from northern Japan showed calm seas and lighted windows. Residents said they barely felt the quake.
The agency, however, warned larger waves could follow.
