What to expect visiting Japan?

Question:

I really want to visit one day.

Answer:

Only one day? There's so much to do! It really depends where you're going. If you're a foreigner, except a lot of people glancing at you. Here's a list of other things:
1. Expect shopkeepers to keep saying the same phrases over and over in a weird voice such as "Irrashaimasu!"
2. Expect trains to be packed (If in Tokyo) around 7:30-10am and all the conducters to sound like they're plugging their noses when speaking on the intercom.
3. Expect cars to go very close to you when you walk on the streets, to the point you feel like you're going to get hit.
4. Expect to see practically all the men in business suits and a lot of kids in school uniforms.
5. Expect to find random temples and shrines in even the busiest of areas
6. Expect to find that Japan isn't just about anime and video games.
7. Expect the TV to only have variety shows on practically every channel.
8. Expect 7Elevens to be more than just a convenient store, and learn how awesome the Daiso, Donkey hotei and Lawson's 100 yen store are
9. Expect people to be too polite, except in trains. Every man to themself there...
10. Expect most restaurants to consist of the following ingredients: chicken or pork, noodles like ramen and udon, curry, raw seafood (sushi and sashimi), eggs (raw or cooked), seaweed, cabbage, tomato and ginger
11. Expect karaoke places to be seen everywhere
12. Expect Japan to be very clean, and yet it's impossible to find a trash can when you need one!
13. Expect to have to separate your trash into burnables and non-burnables
14. Expect Japan to be very expensive, but it's super easy to find affordable restaurants

I could go on and on, but I hope this answers your question somewhat:)
