Why You Should Visit
Radio Osaka's free fan festival on Labor Thanksgiving Day, held at Taiyo-no-Hiroba Plaza in Osaka Castle Park. Formerly called the OBC Radio Matsuri, it returns to this plaza after two years under a new name. The main stage hosts a live public broadcast of "Wada Mamiko no Mimiyori Dango" and a gathering of the station's personalities, so you can hear familiar radio voices in person. New this year is a record and CD swap, alongside a stamp rally and food and shopping booths. A good pick for Radio Osaka listeners and families looking for an autumn day out at Osaka Castle Park.
