How to say “liar” in Japanese?
PRONUNCIATION IN JAPANESE

EXAMPLE
1) あなたは嘘つきです。あなたを信用できません / あなたはうそつきです。あなたをしんようできません (anatawa usotukidesu. anatao sinyoudekimasen)
You’re a liar. I don’t believe you.

NOTE:
Calling someone a liar in Japanese is a pretty strong statement considering the nature of Japanese language. In most situation people would try to avoid direct confrontation, unless of course when it comes to a conversation between a couple (husband and wife), then this could be a pretty common phrase.
