Many radio sites linking to Japanese radio stations often have links that don't work and are just a hassle to navigate through. I've found this little radio software to be the most reliable way to find Japanese radio stations: RadioSure.
Just search for "Japanese" in the search window and it will list all Japanese stations. Some I'd recommend for purely hearing people talking would be:
Radio Tsukuba / Sankakuyama / Smile FM
