3.1. Early Career and Major Competitions
Ishikawa's early career saw him emerge as a formidable competitor in the pre-war and post-war Judo scene in Japan. In 1940, he participated in the Kigen Nisen Roppyakunen Hoshuku Tenran Budō Taikai (Imperial Grand Martial Arts Tournament in Celebration of the 2600th Anniversary of the Imperial Reign), often considered the de facto national championship. In this event, he reached the final of the designated competitors' division, where he faced his formidable rival, Masahiko Kimura. Due to tension, Ishikawa was reportedly overwhelmed by Kimura, suffering a decisive defeat.
Determined to avenge his loss to Kimura, Ishikawa intensified his training, refining his standing techniques such as O-soto-gari, Ippon-seoi-nage, and Uchi-mata. He also dedicated himself to mastering ground techniques (Ne-waza), learning from the renowned 9th Dan, Tsunejiro Oda, whose style was known as "Tsunejiro-ryu." Following the end of the Second Sino-Japanese War and his return from Manchuria, he became a Judo instructor for the Metropolitan Police Department (Japan).

Ishikawa's performances in the All-Japan Judo Championships cemented his reputation. In the 1949 tournament, he navigated a challenging path, defeating Hideo Nihei (5th Dan) in the first round, Hiroshi Yamamoto (6th Dan) in the second, and Toshiro Daigo (5th Dan) in the third. The final was a highly anticipated rematch against his long-standing rival, Masahiko Kimura. After a fierce and unresolved battle, the match ended in a draw, resulting in both Ishikawa and Kimura being declared co-champions. Kimura, in a gesture of sportsmanship, arranged for the championship flag to be taken home by Ishikawa. In the same year, Ishikawa was promoted to 7th Dan.
He entered the 1950 All-Japan Judo Championships with the goal of avenging his previous loss to Kimura, but Kimura had transitioned to professional Judo and did not participate, reportedly disappointing Ishikawa. Nevertheless, Ishikawa dominated the tournament, defeating Takamitsu Toko (6th Dan) in the first round, Kenshiro Abe (7th Dan) in the second, Yasuhiko Matsumoto (6th Dan) in the third, and Toshiro Daigo (6th Dan) in the semi-finals. In the final, he defeated Iwao Hirose (7th Dan) by decision, securing his first outright championship title.
