What I want to know is mostly these:
> How much did it cost?
> How long did you stay there for?
> How much Japanese did you know?
> What was the most expensive part of your trip (besides plane ticket)? And the cheapest?
> How many towns did you visit?
> Did you enjoy it?
Bonus question: in hindsight, now that you've been there, what are some things you discovered that would've helped you save some money during your trip?
