you may ever learn how to say 'no' in japanese that is いいえ (iie) but actually there is another word for you to use that is ちがいます(chigaimasu), by its meaning is 'different' .

In the previous post is "thank you" word, how about "you are welcome" ? 

the most casual word to use is "douita shimashite" but in japanese we hardly use it. 

we all know how to say thank you in japanese "arigatou " ありがとう but there is still another word used to express your appreciation, to thanks for others' kindness. 

There are japanese phrases to say when you are leaving and coming back home. Because some of the general greeting word like こんにちは(konnichiwa) Good afternoon,　こんばんは(kombanwa) Good evening,　さようなら(sayounara) Goodbye are hardly used among family members.

I was invited to have a dinner at my japanese friend's house. The food was served, and before we all started eating, there is japanese phrase to be said..

Here is another phrase that can be used as　しつれいします。 

邪魔(jama) by its meaning is an intervention, a disturbance.

Japanese seems to use apologies all the time, and that culture makes the foreigner uncomfortable with. It's too formal and not sincere. But for japanese, they use it to express the gratitude, their sincereness, and apology for being rude.

失礼(shitsurei) by its meaning is rudeness.
