Relatives of the employees had sued Shichi-ju-shichi Bank, claiming it should have foreseen a tsunami would have been higher than the 32-foot-tall building, Japan Today reported Wednesday.
The three employees were among 12 bank workers who died as they sought protection from the massive tidal wave when it hit Miyagi prefecture March 11, 2011. A 13th person on the roof survived.
In his ruling, Sendai district judge Norio Saki said, "It would have been difficult to predict that a tsunami 20 meters (66 feet) high would hit the building."
Family members of the three employees had sought $2.2 million in damages.
