When Payet was "uchi-deshi" at the Yoshinkan, there was a notebook full of technical information and anecdotes of Gozo Shioda. Payet taught himself to read Japanese with the aim of translating this notebook. In 1991, the notebook was released in Japanese, and Canadian aikido practitioner Christopher Johnston made a translation of the book. Together, Payet and Johnston worked with the Yoshinkan hombu and produced an English translation of the book under the title "Aikido Shugyo: Harmony in Confrontation", published by Shindokan Books.
