Shioda returned to Japan in 1946 and spent several months trying to locate his family on Kyushu. He rejoined Ueshiba for a month of intensive training, but was forced to dedicate the next few years to earning a living in post-war Japan. He began teaching aikido in 1950. That year, he taught for the company Nihon Kokan at the Asano Shipyards in Yokohama. In 1954, he entered the All Japan Kobudo demonstration, and won the prize for the most outstanding demonstration. This marked a turning point for the growth of aikido. Shioda's performance attracted sponsorship that enabled him to build an aikido "dōjō" (training hall).
