Does anyone know what good deals for high end shopping in Tokyo would be? Example Chanel, hermes..? Meaning a good on pricing after VAT returns?
I don't think you will be seeing any bargains at all...it's not that kind of marketplace.
Price you get will be the pretax price (which is 8%), but prices for high end goods in Japan are higher than many other parts of the world.
Also the USD/JPY exchange rate isn't so great now that you'd get better pricing. It's possible some stores will carry styles/items that you won't find in other countries or even other stores nearby. If looking for the basic stuff that you can get anywhere don't bother getting it there and take up luggage space.
I forgot to mention Uniqlo! If you have short arms, their Japanese sizes fit better than their American sizes. If I get an American Uniqlo size L, the arms are too long. But a Uniqlo Japanese size XL fits me nicely.
