Turning Japanese...

O wise LJ, I need your fu: does anybody out there speak Japanese? What I need, all I need is the Japanese for 'very small'. Or a way of saying 'very small', if (as I assume) there are many. I have prodded various internet translation devices, and they have been variously and entirely unhelpful (one objected at the quantity of text I was asking it to handle, one offered me kanji which I cannot read - it's got to be romaji, it's for an English actor to say - and so on), and so I turn to you.

Don't ask for context, even if context is crucial for a proper answer; it's being said deliberately out of context. I am perpetrating a referential joke in two languages, and ought to be ashamed of myself, but hey...
