Just say NO! (to Japanese police)
Topic: adviceS
If the cops come to call in Japan....
1) Politely avoid as best you can, leaving your house and willing going to the cop station.
An arrest warrant in Japan is tough to get and most likely they'll pick on some other FG. Important to note that police can do almost anything, including searching your home, "IF" you give them permission or allow it. So, sure police can "ask" but you don't have to give them an answer and the crucial point is how they behave when the answer is no, "I don't want to talk to you. Once you're in the station, the cops have 12+ days to torture you without formal charges: Think rubber hose, dogleash optional.
2) Lawyers in Japan are honor-bound to "serve society" as well as you. Sounds nice, don't it. It AIN'T. Japanese lawyers serve society by ratting you out; client privilege is not sacrosanct in Japan.
3) Except for driving, ALWAYS claim you were drunk.
The Shinto gods were all drunks and all things can be forgiven if you were drunk. Pour booze all over your clothing and take a good swig.
Oh and "Absolutely refuse to be budged."
