The first video is more than 6 minutes long- and shows the tsunami approach the videographer perched on a concrete walkway in the middle of a Japanese town.
The ocean surge overtakes the videographer's position and keeps rising- with larger and larger obects floating by.
Toward the end of the video- structures that the person was videoing with water begining to surge into them are being torn apart by the rising water and you see people clinging desperately to the crumbling structures.
The second new video shows the tsunami lap up against- then spill over a floodwall in the town of Miyako- pulling boats loosened by the gigantic floodwave over the inundated floodwall into the town.
The last video is of a Japanese television news broadcast- showing before and after videos and photos of several devastated areas.
