Here’s a link to a funny piece I helped work on. Fukubukuro (‘lucky bags’) have been around in Japan since at least the 20th century, where stores sell mystery bags at varying prices.
This year, Apple took the cake. A ¥300000 (approx. A$300) bag got some shoppers a new laptop or Ipad. They only had to line up the night before and sit in the snow to get it.
There are also ‘unlucky bags’ or ‘depression bags’: one shopper unwittingly picked up eight copies of the same game in his.
