While he can also be seen in Japanese television drama, Fukuyama is best known for his singing career. His 1992 breakout single "Good night" gained a wide audience because of its tie-in with a TV drama. In 1993, he made his first appearance in Kōhaku Uta Gassen, on which only successful J-pop and enka artists are invited to perform. Propelled by the success of Hitotsu Yane no Shita, in which he played Chinichan, the second older brother in the Kashiwagi family, he had his first million-selling single, "It's Only Love/Sorry Baby", in 1994. His 1995 single "Hello" became the second highest selling single that year.
