To you. It is just another shop. The duty free bit is that the shop is allowed to sell goods that the government waived duties on (import tariffs etc). So they can be lower priced than the same goods sold elsewhere in the country.
You can open the goods any time after purchase like any other goods. You can even consume the goods while waiting in the airport terminal. Since you are leaving the country, Japan doesn’t really care what you do with the goods since you”re not even bringing them back into Japan.
The goods that you need to pay a bit of attention to are things like cigarettes and liquor. But the problem is when ARRIVING not departing. Most countries only allow travelers to bring a limited amount of these goods when entering the country. (Generally 1 liter of liquor and 1 carton of cigarettes is safe. But some countries have started to not allow cigarettes at all).
If you do exceed the limit the worse case is that you have to give up the goods to customs upon arrival. The more likely case is that you will be charged duties at customs on arrival.
