What's inside that bag?
On the first three days of January, many people in Japan go to the near by mall, outlets and department stores to get the "Fukubukuro" or Lucky Bags. The customers do not know the contents of the bag, but purchase it because it's cheap price relative to their actual values. It is fun to open the bag and find out what is inside.
I recommend you to go to your favorite store, whether that may be Nike, a stationery store or a supermarket, and pick up a Fukubukuro for yourself!
