I'm with you guys on the Japanese pronunciation, but I disagree with the 'oo' transliteration... That implies a sound like the ou in 'you'...
The actual sound is alien to the average english-speaking throat... I'd choose to write it as 'uh', I guess...
For you dutchies out there: it's between the u in 'kut' and the uu in 'zuur'

I'm pronounce it yuke.

More like U kay

I just say u k e
spell it out

...Because its a Japanese word?

I know this doesn't have to do with pronouncing it, but whatever.
Uke is the traditional "receiver" of martial arts while Tori is the "chooser".
It's the dude that gets the bitch end of the martial arts stick.

There might be a pronunciation on that page.

And what does definition have to do with pronunciation?

I forgot to add the part that I meant to add in the first place.

There isn't.
Not in english at least.

Pronunciation: (IPA: [ɯkɛ])

IPA = International Phonetic Alphabet aka how to say stuff.

EDIT: Also, according to that it's pronounced uu-keh.
