How to say "hi" in Japanese

• こんちは
  interjectionA breezy shortened 'hi' or 'good day' for greeting friends and acquaintances in passing; its casual, clipped ring fits relaxed exchanges.
• ちわっす
  interjectionCovers 'hi' in its most casual, 'yo'-like sense; the stretched, joking sound gives it a playful, bantering flavor, tossed out to friends in relaxed moments.
• アンニョン
  interjectionA Korean loanword greeting covering 'hi' or 'hey'; its unmistakably foreign flavor makes it a playful, jokey hello you throw out for effect among friends.
• やあやあ
  interjectionCovers 'hi' and 'hello' as men's speech: a brisk, hearty greeting a man throws to an acquaintance; for a neutral 'hi' it is seldom the choice, being distinctly masculine.
• チョリース
  interjectionSlang for 'hi' or 'hello'; the jokey, streetwise flavor makes it a showy greeting among friends, and for a plain 'hi' it is seldom the word you want.

All five are casual greetings for 'hi', differing mainly in flavor: 「こんちは」 is the most ordinary, 「ちわっす」 is playful 'yo'-like banter, 「アンニョン」 is a Korean borrowing, 「やあやあ」 is men's speech, and 「チョリース」 is slang.
