Just watched this Toraguchi Tuesday video (name inspired by Waza Wednesday? if so, well done, Noah :)
It shows the middle part of Seienchin (or Seiyunchin in Goju Ryu) as being a Kata Guruma, or Shoulder Wheel throw.
For reference, here is the Kata (very close to the way I practice it. the relevant motions are at 1:28-1:34):
And here is the Toraguchi take on it:
What do you think about this Bunkai? An interesting idea, I must admit, but are you convinced? Does the motions of the Kata really look like a Kata Guruma to you?
For comparison, Iain shows a Kata Guruma Bunkai in Enpi (Shotokan version of Wanshu). Here it is:
Another example is Iain's take on the last move in Kosokun Dai (Kushanku/Kanku Dai), which shows a Kata Guruma variation:
Iain's examples are more convincing in my opinion, as they follow the motions of the Kata more accurately.
If you are not convinced that these motions in Seienchin actually depicts a Kata Guruma, than what is your take on them?
I do like Iain's take on these motions, being an arm lift + head push/control combination, which can also follow from the previous part of the Kata as well as be a set-up for the next part of the Kata (2:21-2:28 in this video):
Threw around some ideas I found, but interested in getting other views as well.
