I don't know why "Fukubukuro" tradition has been continued until now. I think it's a strange tradition, because I don't wanna buy one which I don't know what's inside.
Fukubukuro is similar to grab bag. It's filled with unknown (and somewhat mysterious) items randomly. Of course it's discounted, but actually I don't like it. I wanna buy one which I really want even if it's expensive.
In my opinion, buying Fukubukuro is like a New Year's first trial of one's fortune, so it's not shopping but gamble. That's why I don't like it.
I left Akihabara and went to Ueno. It's completely aimless. Just strolling. I know I ended up wasting my time and money, but it's not so bad. I did I really wanted to do. Better than buying Fukubukuro and end up with a load of unwanted things. Just strolling, I'm happy with that.
