Hundreds of different jingles separate programs from commercials; they are generally played at the same decibel level and are variations on a single melody.

[citation needed] J-Wave has been broadcast via satellite since 1994, and some of its programs also air on some community radio stations in Japan.

The station had a large fanbase because of its unusual programming style, playing music non-stop except for jingles and breaks for news, traffic and weather.

Specials started to air around this time, and the station took steps to attract a listener base desirable for higher ad revenues.

On October 1, 2003, J-WAVE moved its head office to the 33rd floor of the Roppongi Hills Mori Tower in Minato, Tokyo.
