A curious characteristic of the old style is that it did not support much of the esoteric ways that (some contend) evolved with post-World War II traditional Aikido and some of its offshoots. At one point Kisshomaru Ueshiba, the headmaster and son of the aikido founder, reputedly asked Mochizuki to refrain from using the name aikido to refer to the aiki portion of his system. The system although still employing the term aikido is also known to use the term "aiki budo" to refer to this part of the art. Minoru Mochizuki's 1932 licence from Ueshiba was in Daitō-ryū Aiki-jūjutsu as Ueshiba had not yet renamed the art he was teaching (which would come to be called Aikido). Still Mochizuki continued to enjoy a warm relationship with Morihei Ueshiba even in his later years.
