can expect to see an increased police presence throughout the city. Well, coach, who helped build the sport of judo in San Jose and in the Olympics, has died. Coach Yosh Yoshida was 104 years old. His fellow coaches and students say he leaves behind quite a legacy. Here's NBC Bay Area's Ian Cull. A solemn mood swept through San Jose State today on the news. Legendary judo coach Yoshida had died. Mike Swain coached under Yoshida for nearly 40 years. He's like the Godfather or the grandfather of American judo. Yoshida led the charge to make judo an Olympic sport. He was the first U.S. Olympic judo team coach and established the first collegiate national championships. Yoshida Hall houses the dojo on campus, but its history runs much deeper. His whole life story is right here in this. In this hall. It once was a processing site where Japanese Americans were sent before they were taken to internment camps. Yoshida's family went through here as he went off to fight for America in World War two. So this is really special to have his building, this building, named after a Japanese American citizen down the hall, the trophy case shares Yoshida's accomplishments over 70 years. And there's a wall of Olympians he helped coach. Coach Uchida was such a great teacher and he was a life coach to so many students. He proudly talked about them when we interviewed him over the years. Tell me about Marty. Oh, Marty is one of our best that we have. She's not only a hard working person, but a real determined. But his former students say getting good grades and being a good person was his biggest lesson at the time. I didn't understand it. But now that I've graduated, I've accomplished what I wanted in judo. Without school, I wouldn't. I wouldn't be in the position that I am today. So, you know, I credit him for teaching me that at a very young age. Colton Brown is a two time Olympian from SJSU who spoke with us from Spain, where he's helping team USA prepare for the summer Olympics. I'm grateful he was the greatest man I've ever known, and I'm grateful for the lessons that he taught me. And my goal now my job, now my duty is to, is to use this to impact the next generation in the most positive of ways. And if I can be half the man that he was, then I've accomplished something with my life. Yoshida's accomplishments go far beyond judo. He helped revitalize San Jose's Japantown. His daughter tells me by phone. They're preparing for a small private service tomorrow, and said they appreciate all the love and support for their beloved father
