I've been listening to 'American Top 40' since 1976.
But I found that Radio Kanto(RF Radio Nippon) broadcasted 'American Top 40 Japanese Version' in January,1977.
And RF Radio Nippon ended it in September,1986.
During these 10 years are golden years for me.
I have almost No.1 singles during these years.
So, I'll show you.
