In 1970 Kazuhiko Yamashita visited the Church's pavilion at the World's Fair in Osaka, Japan. Impressed with the missionaries' attitudes and the Latter-day Saint film, "Man's Search for Happiness," he wrote down his name and number and turned in a self-referral. Six months later, the missionaries called on him. "Those missionaries were great," he said. "They were a good example to me. I was interested in their life and service. They were young and polite and I wanted to hear their message."
