Japanese phrase
面目ありません。 men boku a ri ma se n
Meaning
I am terribly sorry.
When to use it
A strong apology for causing trouble or failing others. It sounds humble and somewhat old-fashioned, so it is less common in casual conversation.
Example dialogue
約束を破って、面目ありません。 yaku soku o yabu tte men boku a ri ma se n
I am terribly sorry for breaking my promise.
次は気をつけてください。 tsugi wa ki o tsu ke te ku da sa i
Please be more careful next time.
