祝儀袋（しゅうぎぶくろ）shugibukuro

If you have ever been invited to a Japanese wedding, you have probably experienced the complexity of the process of attending. You need to prepare a special type of envelope that you insert crisp notes of ¥10,000 (usually between to ¥30,000-50,000 in total) that must be folded in a specific manner before finally putting your name and address on it.

This music is a time signal for all the children in the local neighborhood that it's starting to get late and that they should start heading home.

非常（ひじょう）hijo

There are many different words centered around an emergency, which might be one of the reasons why Japan appears to be a very safe society.

Why not try and use the phrase at work and see if you can get some slack?

自動販売機（じどうはんばいき）jidohanbaiki
