Where can i buy gatsby in tokyo ?

Hi, I am in Tokyo for a few days.
I want to buy gatsby in Tokyo but i don't know where.
I made a lot of research and I didn't find. It's a japanese product and I only find online shop and in America...

all convenience store,supermarket,drugstore.....

i agree with KK... its more like where CANT you buy gatsby that you should be asking.

its everywhere.

.............. Its literally everywhere. Anyways, there are a lot of other brands that can be used instead of gatsby, and some feel even better too. Try a new brand, it might be better. You can find gatsby anywhere in america too, so I suggest buying something you can't find in America.
