When I was a kid — long, long ago — my friends and I used to flaunt our juvenile erudition by spelling out what was supposedly the longest word in the English language: antidisestablishmentarianism. (Oh wow, the MS Word software just informed me that I spelled it correctly. But don't ask me what it means.)

Actually, I heard there's a train station somewhere in Wales whose name is even longer. Written out, it looks like a cat did a tap dance over the keyboard.

But what about kanji? Is there one that can claim to be the longest — as measured by the number of brush strokes — and therefore the most intimidating?
