Buying Kokeshi Dolls in Tokyo?

Hi, I will be making my 2nd trip to Tokyo next month. The last time I was there I bought 3 Kokeshi Dolls, one from the touristy stalls in Asakusa, one from outside a shrine in Nara deer park and one from the airport on the way back home. I will only be in Tokyo for 2 days this time (we will be going on a ski trip to Hakuba) so I was wondering where would be the best place to pick up more Kokeshi dolls? I would also love an antique kokeshi doll and was wondering if there were any particular district in Tokyo which sells them. Does anyone also know of a shop which just sells Kokeshi dolls? Thanks in advance :)

I saw some at Oriental Bazaar in Omotesando. Lots of other Japanese souvenirs, too.
