As Kano had fused the forms of traditional jujutsu he had learned, with elements as different as ground work from the Fusen ryu and Western wrestling tactics so too did Mochizuki strive to learn many different arts in order to expand his overall understanding of fighting methods. Indeed, many of his early explorations in arts such as iaido, jodo and classical forms of jujutsu were at the suggestion of Kano during his time at the Kodokan. He expanded this to include an investigation of Western boxing, karate and classical Japanese swordsmanship. Conversely when he made the suggestion to Ueshiba that aikidoka might benefit from a knowledge of the skilled striking techniques employed by karate practitioners his suggestion met with no enthusiasm.
