In March 2009, amid speculation he would retire, he announced his intention to move to the United States to study English. I want to swim for Japan once again. After Beijing my heart wasn't in it but I still have something left. After I saw [Japan win] the World Baseball Classic, I realised how much I love the Japanese flag. (FINA Aquatics World Magazine, Mar 2010; swimmingworldmagazine.com, 01 Mar 2009; hansonmediagroup.com.au, 01 Mar 2009)
I AM THE SWIMMER
In June 2008 he wore a T-shirt stating 'I am the swimmer' to protest the Japan Swimming Federation's restrictions on which swimsuits Japanese competitors could compete in at the Japan Open. "It's a shame Japanese swimmers haven't been permitted to wear the Speedo suit." (swimmingworldmagazine.com, 06 Jun 2008)
DOLPHIN KICK CONTROVERSY
His gold medal in the 100m breaststroke at the 2004 Olympic Games in Athens came under question when United States' backstroker Aaron Peirsol accused him of using an illegal dolphin kick. Peirsol claimed Kitajima had employed the illegal kick on entering the pool to give him extra momentum, despite the rules requiring that only a breaststroke-type kick be used in the race. "He knows that [the judges] can't see that underwater. He knew what he was doing. It's cheating," Peirsol said. Kitajima's coach, Norimasa Hirai, said he never uses a dolphin kick and Kitajima himself refused comment, saying he had no response to the accusation. (NBC Olympics, 01 Sep 2004)
COMMUNITY INVOLVEMENT
As part of one of Coca-Cola's sponsorship campaigns, he visits local schools and talks to children about his achievements in the hope of inspiring them to take up swimming. (cocacola.co.jp, 22 Jan 2008)
EARLY DAYS
As a young boy in school, he wrote that in the future he was going to be an Olympian. At age seven he joined a swimming team. He swam with all the other kids, just for fun. Then, when he was still at school, he had a chance to swim with Akira Hayashi, Japan's 1994 Asian Games 100m breaststroke champion, and from then on decided he wanted to compete at the Olympic Games. By age 10, he had begun competing in Japan's National Junior Championships.
