The name "Bassai" literally means "to storm the fortress." The frequent double blocking movements in this kata are symbolic of repeated attacks from different positions that would be necessary to penetrate a heavily guarded fortress. The appendage to the name, "Dai" indicates that it is the "big," or the long Bassai kata-as opposed to Bassai Sho, which is the second and shorter Bassai Kata.

This kata is an intermediate one practiced by the Japan Karate association Shotokan Karate students. It is normally taught after Tekki Shodan, that is, at brown belt (3rd kyu) level. It can be chosen as the student's favourite kata for examinations for 2nd kyu to 2nd dan.
