Yamanaka's training regimen included a unique method employed by his coach to maintain his focus and intensity. Whenever Yamanaka would relax during a training session, his coach would throw a pebble at his back as a signal. After the training, Yamanaka was required to collect all the pebbles from the pool bottom, reinforcing discipline and attention.
Throughout his career, Yamanaka was involved in intense rivalries with other top swimmers of his generation. His most notable competitor was Murray Rose of Australia, who consistently edged him out for gold in the 400 meter freestyle at both the 1956 and 1960 Olympics.

Despite these losses, Yamanaka was able to defeat other prominent swimmers, including George Breen, who was later inducted into the International Swimming Hall of Fame.
