After the war, Yutaka Yaguchi was able to resume his education, and was even able to go to university, unlike many of his former school mates. He went to Nihon University in Tokyo, and this is where he first started Shotokan karate. He also joined the JKA at that time. Training was very intense and heavily oriented to conditioning. Mr. Yaguchi graduated with a degree in Marine Biology, but was averse to sailing. After graduation, he found a job with a construction company.
