Although the long あー sound occurs in many words written in katakana, and in some onomatopoeia and interjections (ザーザー, まあ, etc.) it seems to be very rare in words written with kanji. The only example that I know is お母さん{おかあさん}. Is this the only one, or are there other words written with kanji that use this sound?
Clarification: I know there are many cases where two あ sounds meet across a morpheme boundary, e.g. 唐揚げ{からあげ}, which is not what I'm interested in. I'd like a list of kanji which have morpheme-internal readings containing あー.
