In 1976 Kameda moved to Tokyo. He developed a hobby of trying to intercept radio signals from across the ocean, using an instrument called BCL (Broadcast Communications Limited), to hear western-style music. In 1977 he started broadcasting his own radio station (FM KAMEDA) from his room. Three years later he joined Musashi High School and bought his first bass guitar, a Yamaha BB2000. In 1984 Kameda exchanged his Yamaha for a Frettor and got his first Fender Jazz Bass. In 1987 he graduated from Waseda University and began to record self-made demo tapes with his arrangements. One year later he finally began his bassist and arranger-producer career.

In 1999, he participated in the production of Ringo Shiina's first and second album as an arranger, and they were big hits. Because of those hits, he received many commissions to produce music. That started his great success. Since then he has been producing for musicians and bands like Spitz, Ken Hirai, Shikao Suga, Do As Infinity, Angela Aki, and others. He also participates in many musicians' recordings as a session bassist, or plays a bass guitar as a member of various solo singers' tour bands, or temporary bands like Bank Band (2005–present).

From May 2 to 3, 2009, Kameda gathered artists whom he’s had relations with throughout his career, and promoted the music festival "Kame no Ongaeshi."
