Last weeks when I pass by a Sakuraya (General electronics stores) I finish looking to this ad smiling like an idiot.
They are promoting changes in their shops, the ad explains that after their renewal it’s easier to shop and everything is much more intuitive for their clients. Sakuraya is a good place to buy gadgets, if you are traveling and you show your passport you will not have to pay taxes (5% discount). Still, my favorite electronics stores are Yodobahi.
