He was a third Dan in Judo by the time he reached his mid-teens.
At the age of 18 his father sent him to watch a class led by Morihei Ueshiba at the Kobudan. The school was said to be execptional, offering a powerful and extraordinary form of martial art. On his initial visit, warching Morihei Ueshiba throw his opponent about so easily and without any apparent effort, he felt sure that he was witnessing a fraud, but was invited to try his Judo skills against Morihei to see for timself. On launching an attack, he soon found himself Bying in midair, hitting the ground head first, not knowing what had happened. A dazed and bewildered Gozo Shioda was suprised by what had taken place. The very next day which was 24th May 1932, Gozo Shioda joined the Kobudan Dojo as an uchi-deshi or 'residence disciple'.
