Collecting drinks in Japan?

Question:

Going to Japan and thinking of collecting 1 of each drink I find. Should I drink these or leave them in the can? If I open them, should I take off the tab or keep them on? Any other tips or details?

Answer:

What do you plan on doing with them when you leave ? Japan has a ton of different kinds of canned drinks. Some of the Japanese soft drinks are actually made in the US. I once worked for a company that dealt with the pallets the cans were shipped on.
I think you will give up after a while. They'll take up too much space.
