The Japan FM League (JFL; ) is a Japanese commercial radio network. It is organised by J-Wave and was established on 1 October 1993.
JFL's main ideal is to respect the operation of each of its affiliates, letting each affiliate flourish under its own terms. The network is a co-operative, with each affiliate offering its resources when useful. So, for example, when J-Wave wants to air a concert or ask for interviews when a group tours in Nagoya, it can easily borrow the studios of Zip FM (the JFL affiliate there) to help produce what's needed.
