Yea, whisky. Do not buy it and bring it too Japan.

They have all of the top brands at less then the duity free selection. I have seen a bottle of JD for 2k yen, that is 10 GBP or 20 USD.
They have Chivas, J.Walker, Fiddich and all of the rest for less then you will pay at duty free.

I bought three bottles of various whisky with me from duty free only to see them MUCH cheaper in a Japanese liquor store. Let me tell you this, It is cheaper for me to drink JD then beer!
