For those of you living in the modern world, this may not be as neat for you. But I have compiled a list of a couple of Japanese radio signals for the shortwave radio. (Not a conventional radio)
Generally they get picked up at anywhere between three to six in the morning. So, if you feel like listening to some Japanese news, weather, music, interviews and so on check them out. Also, if you aren’t familiar with shortwave radios, this probably isn’t for you.
6055 – Nihon Shortwave Broadcasting Company – Tokyo Japan
11815 – Radio Japan – Tokyo Japan
15310 – Radio Japan – Tokyo Japan
5960 Khz (Japanese) 0200 – 0300 UTC
5060 Khz (Japanese) 0300 – 0400 UTC
11690 Khz (English) * Japanese Lessons 0600 – 0700 UTC
Nihon shortwave is generally the best bet, shortwave stations get kinda messy from time to time, and can be dropped at strange times due to the weather, season, or even certain appliances in your home.
But yeah, I get up early every and listen to Nihon, its a pretty neat station. Sometimes there are interveiws, and music, (the music is kind of a jip, mostly classical)
But yeah, good luck and keep up the froodulence.
