How to say "good-bye" in Japanese

• ツァイチェン
  interjectionA borrowing from Chinese covering both 'good-bye' and 'see you' when parting in expectation of meeting again. Uncommon and normally written in kana, it is seldom the word you want for a plain farewell.
• ばいなら
  expressionA colloquial good-bye for relaxed, informal speech with friends or family rather than formal occasions. Less common as well, it is rarely the choice when you need a neutral farewell.
• オールヴォワール
  interjectionThe French loan phrase au revoir, saying good-bye with the flavor of the French original. Less common and distinctly foreign, it is seldom the neutral word you want for an ordinary farewell.

All three are uncommon farewells rather than everyday choices: 「ツァイチェン」, from Chinese, doubles as a casual 'see you'; 「ばいなら」 is a colloquial good-bye; 「オールヴォワール」 says good-bye with a French flavor.
