yes

THANK YOU FOR YOUR RESPONCE.
>you can stay within the treaty area for 3 months (90 days?) only within a period of 6 months (180 days?).

YesI know about that.
So anyway I must left Schengen treaty countries and if I want to come again this Schengen treaty countries I must stay out side of this area more than 3 monthes.
The best solution is to go back to Japan as soon as possible I think.
But i want to continue to traveland I must go to Swiss.
I have a flight ticket already.
Swiss is not a member of Schengen treaty yet.
So I hope I can enter Swiss.(I KNOW IT IS NOT EASY)
Anyhow I wll have a problem on the border if I take train airplain or bus.
I hope I will go out from here with nothing problems and coninue my travel.
