After having to go through asking friends over in Canada to ship me beloved items in secret packaging through the mail because I had no hope of finding them in Japan, I thought listing a few of the key items you would not want to forget when going to Japan on a short to medium term trip. Girls and boys alike !
This list is also to consider mostly if you will be staying for a medium length stay, which I would consider to be more than two weeks up to 3 months. I suppose then, you would get used to Japan, the products they offer, and could get around to find things there to replace your beloved items you had at home. And in the worst case.... There is always internet shopping.
