This kata was called Heian Godan by Funakoshi Sensei and was introduced in 1907 by Anko Itosu, Shuri-Te style. The theme of this kata is defense against weapons.
Note: Because of its overwhelming use in Wado techniques, if only one hand is mentioned, the other hand is performing a back hikite. Also, unless otherwise mentioned, all jun-tsukis are at the chudan (solar plexus) level.
