Umseting - Enskt-Japanskt - elephant in the living room

I'm looking for an equivalent Japanese expression here -- not a literal translation. I know the words for "elephant" and "living room" already... ;-)

<Admin's remark>
This request is no longer acceptable according to our new submission rules.

means ignoring something very obvious, avoinding to mention something about something clear...
