A 500 meter wide tonado struck the city of Tsukuba (located 50 kilometers North of Tokyo) a few days ago and images of the damage have just come onto TV. The tornado wrecked everything in its path, injured 55 and killed a young boy.
While researchers are still studying the situation, some say that it was possibly a Supercell which caused damage over an area of 15 kilometers.
Somebody took a video of the tornado in Tsukuba and uploaded it to the Tubes.
