where can I get cheap Nanoblocks in tokyo

Hi, my niece wants me to get a lots of Nanoblocks for her.
Can anyone recommend me a place or shop in tokyo to get it?

Thanks!

Try Toys "R" Us http://www2.toysrus.co.jp/store/en/kanto2.html#tokyo

The Yamashiro-ya toy store across the street from Ueno Station has them on the third floor.

nanoblocks are cheaper at yodobashi than at tokyu hands. didn't pay attention prices at other stores though.

When I was there a couple of months ago, they were considerably cheaper at Yodobashi Camera than they were at Yamashiro-ya. I bought the large Himeji Castle set for my brother at Yodobashi for 3000 yen less than it was at Yamashiro-ya.

thanks for all the suggestions!
3000 yen is like 10% difference! will visit Yodobashi Camera to do mass purchase!

anymore great suggestion?

You can always check amazon.com in Japan for their price. Get the stuff shipped to your hotel.

They sell lots of nanoblocks, and you won't have to waste your time shopping for them during your trip. There will be no problem with your hotel accepting the shipment for you.
