More on green tea being good for cancer blocking, so since Japan
Tobacco is also into the soft drink business, surely there's
cross-promotion possibilities here?

BTW, I remember hearing somewhere that the Morning Set was invented in
Osaka, but originally it was a cup of coffee and two fags. Replace the
drink with green tea, et voila, the perfect Salaryman breakfast.

I jest of course, but this is Japan, so...
