(I can't speak Japanese, sorry.) I spend 2 years in the US, and fall in love with Root Beer so much! But now, I'm in China, it's so hard to find that kind of Root Beer that I was drinking in the US, Their all drink mixes in China, that is a no, DO NOT TRY THAT! Maybe Ponpoko and Peanut kun think this is a bad drink, but when you get used to it, you'll love it, trust me.
