TaKaRa makes a very common cheap alcoholic drink called chu-hi. Not to be confused with hi-chew candy, chu-hi is a fruit-flavored beverage generally found in cans, and usually is priced a decent bit cheaper than regular beer. I've seen cans for around a dollar each.
But as you've guessed, my interest was in the other side of the can. This one sports a Rakuten Eagles logo. That puts me at three team-affiliated beverage containers so far! I guess there are nine to go.
