Fukubukuro, sealed lucky bag
It was about 8 am in the morning on 2 January. People are waiting in line in front of department store to buy fuku-bukuro, sealed lucky bag. It is filled with random goods and are sold at reasonable price, about 50 percent off. People want to buy them partly because of a lavish event. Stores wanted to sell them mainly because they want to get rid of the excess merchandises. But if sellers put only unpopular items in lucky bag, people would not buy them. So sellers may mix better items with the unpopular things in the bags, I would think.
I have not bought the bag simply because I don't want to have unnecessary stuffs.
