jisho.org translates enryo as diffidence; restraint; reserve; discretion; tact; thoughtfulness, which I think is very understandable from an American perspective. It is not so bad that these qualities are highly valued. Sometimes I wish they were more valued here.

I also like that enryo can be used in enryo suru as a verb. e.g. Enryo shinaide - don't hesitate.
