Greeting: The Japanese language has many linguistic concepts along with delicate nuances which are nonexistent in other cultural areas such as itadakimasu (expression of gratitude before meals), gochisosama (deshita) (phrase used after one has been treated (especially after meals), tadaima (I'm home!), okaeri (nasai) (welcome home), itterasshai (have a good day), ittekimasu (I'm going now), shitsureishimasu (shita) (excuse me), ojamashimasu (shita) (excuse me for disturbing (interrupting) you), etc.
あいさつ：いただきます、ごちそうさま（でした）、ただいま、おかえり（なさい）、いってらっしゃい、いってきます、失礼します（した）、お邪魔します（した）など、他の文化圏にはない微妙なニュアンスをともなう言語概念が多い。
