Japanese contradiction

So.. let's get back to talking about Japan.. As I said before, the country is beautiful, the food is great.. The girls are petite and some are cute.. most have crooked teeth, all have LV or Burberry purses. There is just some things I do not understand about this culture thou:

Why is it that people work so late, yet shops and stores closes so early. When do they have time to go grocery shopping? The bank?

Why doesn't 7-Eleven in Japan have Slurpees? I mean come on.. 7-Eleven and Slurpess are like synonymous to each other!

Speaking of convenient stores, in front of every Lawson and AM/PM, there are recycling bins for you to recycle your paper, plastic and cans.. but no where on the streets, are there any garbage cans.. yet the streets are some of the cleanest I have ever seen. The only garbage cans I have encountered are all in JR stations.

Everyone and their mother smokes in this country. There is an age restriction on when you can start smoking. (21 I think) but there are cigarette vending machines in every other block.

Finally, red lights doesn't mean anything in Japan. When you stand in a intersection, green means go, yellow means go faster and red means go before a pedestrian gets in front of you. And they think we have a problem with red light runners here in the state.
