what is your type
Japan is really a convenient country. You can almost get anything at any time. There are a lot of convenient stores everywhere, which open for 24 hours.
You can get drink from vending machines whenever you are thirst.
Also I found interesting thing. You can get condoms from the vending machines. There was a more interesting machine near where I live. The condoms were sorted according to your blood type, ie, there are A B AB and O types condoms there. I did not understand how that works.
