market in tokyo - 2009 golden week?

We are in Tokyo for three days during the autumn golden week holiday (ie right now) - want to visit a good market for interesting old fabrics, ceramics, kimono etc etc... any suggestions.
Is there still a market ar Yoyogi park - it isn't mentioned on the paperlantern website.
What about the Ooi Keiba-jo race track flea market? Is it an interesting one or lots of modern stuff (which we don't really want)?
Anyway how do you get there ie Ooi Keiba-jo race track. We are staying in Asakusa...
hope someone can send help quickly!

Welll there were no answers to our question yesterday, so we went out to the Oikeibajo market this morning... a big flea market all right but not a lot of interesting stuff for us anyway... lots of second hand clothes and old hardware and a few toys etc - no fabrics, old kimono etc etc which was what we had been hoping for. To be honest, it was a long way and not really worth it - good to ride the monorail though...

Maybe for second-hand kimono, you might want to look in at a shop (it's actually a chain store) called "Tansu-ya." There are a few locations in and around Asakusa, so you could ask at the hotel...
