There's no textual context, but I'll give you the best situational context I can. I saw this sign in 2010 on the wall in a bathroom at the Mt. Aso Tourist Info Center in Kyushu, Japan. Unfortunately, the original Japanese was nowhere to be found. And nobody caught me taking a picture in the toilet! I kind of feel like the English might be telling you to throw toilet paper away rather than flushing it (don't remember if there was a trash can) but that's not a common practice here. It's very likely that the Korean is gibberish as well, but I'd appreciate any insight (or guesses!) as to the meaning. Thanks in advance!
