Watch out for misleading labels in Japan
Don't drink soup stock (dashi) ...unless you want to
There have been some convenient, but very misleading trends in consumerism in Japan leading non-Japanese reading visitors and residents to making annoying and sometimes dangerous mistakes.
For example, above you can see a だし Dashi (soup stock) vending machine right next to a normal drink machine. Sure, it's more expensive and there is a flying fish on it, but there is nothing stopping you from thinking it is a regional delicacy drink that you want to try.
I have meet a few visitors who have spent the 450 yen on the "drink" only to be utterly disappointed.
Then there is the latest advertising style of Chu-hai alcoholic cocktail type drinks which feature fruit pictures and look just like juice if you don't notice the ALC 5% or understand the 酒 kanji you may make the mistake. I have met a few families that mistakenly gave these to their children who then (luckily) spat it out. But this is quite a serious safety issue that I hope Kirin and other major brands start taking more seriously.
