This is the Koshiki no Kata, performed by Mas Blonk, and Richard de Bijl
Koshiki no Kata (古式の形:こしきのかた, Koshiki no Kata) is a kata (a set of prearranged techniques) in Judo.
It is also known as Kito-ryu no Kata. It consists of 21 techniques originally belonging to the Kito School of jujutsu. Jigoro Kano revised the techniques and incorporated them into a kata in order to preserve the historical source of judo.
