To Penetrate the Fortress (Minor)
 

Bassai Dai literally means "to extract and block off" but this is taken to mean "to storm (penatrate) a fortress”s. Bassai dai is one of the variations of the Passai Kata that is practiced in Shotokan Karate, normally starting at 3rd Kyu. Shotokan houses two Bassai Kata, Dai and Sho. Dai means greater while Sho means lesser or minor. Bassai Sho is taught at the advanced level after mastery of Bassai dai. Bassai Dai is characterized by repeated changes in blocking to simulate the feeling of shifting from a situation of disadvantage to a position of advantage.

Bassai Dai is often mistranslated, The first part of the name (batsu) means to extract or remove, not to penetrate. The name to Penetrate a fortress seems to be more clearly descriptive of the attitude a student should have when practicing the Kata so for my money it is an adequate translation, if not correct 100%.

Strange Hands

See Enpi kata

Enpi comes from the Okinawan martial art of Tomari-te, where it first appeared in 1683 . It is believed to have been influenced by Chinese boxing. It was originally called Wansu.

Funakoshi Ginchin changed the names of many of the kata, in an effort to make the Okinawan art more palatable to the then nationalistic Japanese. Enpi was no exception as he changed the name from 'Wansi' to 'Enpi' when he moved to the Japanese mainland in the 1920's.

The most commonly accepted theory about its creation and development is that Sappushi Wang Ji, an official from Xiuning, taught the kata while serving on Okinawa. Legend has that Wang Ji had the habit of throwing and jumping on his adversaries. Because of this dynamic form of combat, this kata resembles a swallow in flight.

Others suggest that Enpi was a product of the interaction between Okinawans and the so-called '36 Chinese Families' that immigrated to the islands in the late 1300s. Still other teachers believe that it was based upon Sasaki Kojiro's sword techniques, because they were also said to resemble a swallow.
