This is a font Koreans ALWAYS use when they try to show something “Fun and Hip” in Japan.
The Japanese writing used in this bottle is a classic Korean design decision; it is playful to a foreign eye, but it is quite disconcerting to Japanese designers who I showed it to. It seems to arouse the same feelings as Comic Sans does in English.
That entire bottle design is terrible, but I plan on talking about that in more detail when I have a better picture :/
-edit- Got rid of the link to a blog with an image that got pissy about hotlinking. No google juice for you, good sir.
