Heian Nidan was originally taught as the first Kata for new
students. Its connection with Kanku Dai (the Central Core of Shotokan
Kata) is quite obvious, as the first half of Heian Nidan is almost exactly the
same as the first half of
Kanku Dai.
The Kata uses a large selection of new techniques:-
| Double handed blocks | |
| Sword hand blocks and strikes | |
| Spear hand strike | |
| Back fist strike | |
| Two different kicks | |
| Reverse punch | |
| Reverse side blocks |

This number of new techniques makes the Kata more difficult to learn than Heian
Shodan and may be the reason why Funakoshi changed the order of the two
Kata.
