As Ishibashi had been practicing Goju-Ryu style of Karate since he was a school student, he was hired by Mas Oyama as a Karate Instructor for his Oyama Dojo and the Kyokushin Kaikan, earning his living expenses that way as well.^[9][10][11]

On the stage, he had roles in the plays Sono hito o shirazu (その人を知らず) (1957) and honō no hito (炎の人) (1958).^[3] After leaving Bungakuza in 1964, he became active in TV dramas and movies.^[2][3]

At the request of Mas Oyama, who is also a senior in Goju-ryu Karate, Ishibashi worked as an instructor at the Oyama Dojo and Kyokushin Kaikan during his early days as an actor.^[7][17] At the time, his Goju-Ryu community disallowed him from teaching Karate at the Oyama's Dojo, because he taught a style independent of Goju-Ryu. But due to Oyama persistently asking Ishibashi, he relented and agreed to teach at Oyama Dojo.^[16]

Ishibashi is one of Oyama's so-called legends and was often asked to show the "10-yen coin bending" at Oyama's Karate demonstrations.^[19] Ishibashi was also present in witnessing Mas Oyama fighting the 550 kg bull at the Denen Coliseum in November 1956.^[20] He is also a "kotei" of Oyama. Many of Oyama's students under the guidance of Ishibashi later played the role furthering the International Karate Organization.

Ishibashi had coached Terutomo Yamazaki, whom Ishibashi expected to be talented when Yamazaki was still a white belt, and taught him one-on-one after the joint training.^[17][21] In his blog, Ishibashi recounts how Yamazaki, who had won the 1st Open Tournament All Japan Karatedo Championships held by the International Karate Organization for the first time, would first tell this to Ishibashi to his joy. Their master-student relationship continued, with Yamazaki, who was adviser to a wine company, often gifting wine to Ishibashi.^[22]

According to Hatsuo Royama; "[Ishibashi] was tall and very flexible, slim and not a [typical karateka], but could easily lift 70-80kg on a bench press." He recounted how Ishibashi managed to completely swarm him in training. Royama also tells that Ishibashi would instruct errors in approach to Kumite.^[18]

Shigeru Oyama said of Ishibashi that "There were three great seniors^{[lower-alpha 3]} at the time [of the conception of Kyokushin]. Mr. Ishibashi was the kindest of [Mas Oyama's] seniors."^[23]
