When you start living and working in Japan, you'll come across expressions in Japanese that are different from those in textbooks, as well as many unfamiliar words.
In addition to your regular studies, the quickest way to master natural Japanese is to learn by speaking directly with Japanese people!
Japanese in daily life

おはよう (Good morning)
ありがとう (Thank you)
おつかれさま (Good work/Good job)
In conversations between family and friends, it's common to shorten words and use them in a more casual way.
またね (See you)
じゃあね (See you)
バイバイ (Bye bye)
Even though they have almost the same meaning, there are various expressions and ways to say it.
今週末何してる (What are you doing this weekend?)
This is asking about weekend plans, but when used between friends, it may carry an intention to invite if they are available.
ちょっと (A little)
大丈夫 (It's okay/I'm fine)
Sometimes used with a nuance different from the direct meaning of the words.
ちょっと means "a little," but it is also used as a way to decline.
大丈夫 can also be used to decline.
いただきます (Let's eat)
ごちそうさま (Thank you for the meal)
These are greetings used before and after meals to express gratitude for the food and the person who prepared it.
They are expressions related to Japan's unique culture and environment, which cannot be directly translated into other languages.
