Wrong. A video of it happening was released a couple of days ago. The tsunami went over the top of the buildings.
Really? I think you need to re-read the release there. Spray certainly reached higher than the buildings and it certainly topped the sea wall, but it did not go over the reactor buildings. I've highlighted the relevent parts for you.

Tougher contingency plans have been ordered for Japanese nuclear power stations in light of the Fukushima Daiichi disaster.A brief video clip released Saturday captures the massive tsunami that crippled Japan's Fukushima Daiichi power plant, showing the wall of water that slammed into the facility and created an ongoing crisis.
The video shows the giant wave generated by the historic March 11 earthquake crashing
over the plant's seawall and engulfing the facility, with one sheet of
spray rising higher than the buildings that house the plant's six reactors. Tokyo Electric Power, the plant's owner, told reporters the wall of water was likely 14 to 15 meters (45 to 48 feet) higher than normal sea levels -- easily overwhelming the plant's 5-meter seawall.
