Interesting Facts

1. Despite there being very few trash cans, there is also very few litter.
2. Along the lines of #1, Japanese trash is quite complex. Each thing has it's own bin (i.e. Combustible, Non-combustable, Plastics, Mixed Papers, Cans, Plastic Bottles)
3. Drivers and bicyclists have a great sense of confidence in their ability to not get into a crash -- but they get awfully close.
4. Trains (besides us ばか外人) are typically very quiet...surprisingly quiet considering how many people are on the train.
5. You can find a sustaining meal of meat and rice （牛丼）for less than 500 YEN (~$4-5)
6. The public transportation system is VERY efficient. The trains and buses are, so far, never late. If they arrive early, they wait at the station.
7. The Japanese version of the Bay Area's Clipper Card can be used ALL OVER JAPAN. Some brands (Suica) can be used as a debit card in a sense -- you can use it to make purchases and buy things in vending machines.
8. There isn't an absence of insects and wildlife in metropolitan Tokyo -- they're all just concentrated in the Parks.
9. SO MANY CICADAS.
10. The toilets have faucets on top of the water tank. You wash your hands with the CLEAN water that will be used in the next flush. Efficiency.
11. There are vending machines literally every block... It's not an understatement. LITERALLY every block.
12. Similar to how America pairs "hot" women and cool cars, Japan pairs cute dressed up girls in costume and video games. (or at least at the Tokyo Game Show they did)
13. If you think that Japanese people always stay on the left since they drive on the left -- BOY ARE YOU WRONG. They always switch up the side pedestrians / bicyclists go on depending on the flow of traffic. Pay attention!
14. At some restaurants (i.e. Burger King or a random Udon place in Harajuku) in Japan, you will hear music played in English, but you will most likely have never heard it before in your life.
15. Sometimes you will hear vulgar hip-hop music in random shops / restaurants in Japan. (I.e. Uniqlo / random Udon place in Harajuku) that definitely do not match the occasion. 
16. Japan has GREAT service everywhere you go. If you're eating in at a McDonalds, then they will most likely bring your food to you after being seated. If you're at Gutara Ramen, they'll follow you out the door to wave to you goodbye.
17. Japanese staff will do their best to help you if you need help with anything.
18. If there's room for ONE MORE PERSON on a train, bus, etc. they WILL fit. Public Transportation in Japan gets crowded like sardines during rush hour.
19. Squat Toilets... enough said. I haven't used it yet.
20. The regular toilets have "Toilet Showers" which "clean your posterior". They also have Bidets... and apparently ones with sound that will hide your ungodly bathroom sounds.
21. In my opinion, I don't think Japan has a direct version of discipline (or so I've experienced). Their technique is to make yourself feel guilty and shamed to make sure you don't do that shit again without directly punishing you.
22. Bus drivers will go into a quiet mumble when talking over the intercom during the night time becoming almost inaudible.
23. Japanese people are much quieter than Americans, so be conscious of the volume of your voice
24. The Japanese name for Corn Dog is ビッグアメリカンドッグ (Big American Dog)
25. Many restaurants (not the nice one, but the ones that are in the $2-8 dollar range) have machines that dispense a ticket with your order after paying. You hand these to the chef dude and they make it. No more waiting in line or waiting for the check!
26. THE PRICE TAG PRICE = PRICE + TAX. REVOLUTIONARY. America, take notes.
27. The bar scene starts at like 8:00pm and ends at around 11:30pm because people need to catch the last train home(Unless you're clubbing -- some people stay out all night)
28. While people in Tokyo wait on escalators on the left and dash on up on the right -- it's the complete opposite in Kyoto... weird.
