Responsibility in Chinese / Japanese...

責任 is the Chinese, Japanese, and Korean word for "responsibility".

責任 can also refer to someone who is willing to take the blame when things go wrong (instead of making excuses or passing the blame to someone else). While this is a noble idea, I think it is getting more rare these days in both eastern and western cultures.

Also associated with the idea of "duty."

職責 is a Chinese and Korean word that means duty or responsibility.

If you have a sense of duty or sense of responsibility, this might be the wall scroll that you want to hang above your desk. It is a great way to quietly remind yourself to take pride in your duties at all times.

In a different context, this can mean "official duties" or "position".

重擔 means heavy burden, difficult task, heavy load, or great responsibility.

守土有責 is a Chinese proverb that expresses one's duty to defend the country.

守 means to guard, to defend, to keep watch, to abide by the law, and/or to observe (rules or ritual).
土 means land, earth, or soil.
有 is a possessive modifier in effect meaning, "is a".
責 means duty or responsibility.

So you get a literal translation of "Protecting [the] land is [a] duty/responsibility".
