Namba aruki à 0:25, 1:20 et 5:10 (visual explanation comparing actual walking and old japanese walking)
This was a no twist walking. So a consequence: people didn't run like us, it was looking like a danse (look at ukiyoe), and it explains how woodcutter were able to run 40 to 50 ri per day (200 km a day), it was an use of an "horizontal fall"
