Rainbow FM community broadcaster for Isahaya and Nagasaki

Description

Rainbow FM is a community radio station associated with the Isahaya area of Nagasaki Prefecture. The official site provides station information, programming material, and local announcements. The station supports local broadcasting functions through community news, program promotion, and listener engagement. For directory users, it is a direct source for a smaller Nagasaki-area radio service. The current Nagasaki subcategory lists NBC Nagasaki only. Rainbow FM would add community-level coverage and help distinguish local FM activity from prefecture-wide broadcasters.
