English High Schools in japan???????????

Im thinking of going to an english international school abroad. right now im at an international school in canada. im thinking of japan for next year (12th grade). I found this cool one called "the american school of japan". its pretty big and outside tokyo i beleive. im not sur if you can board ther though, i think its only for transplanted employees . So do you guys know of any good ones? thanks in advance.

btw, my plan B is australia.

This fairly recent thread:

High Schools in Japan mainly in Osaka and Sapporo..

contained some information about international schools.

I wonder if the OP could get a visa to attend an international school in Japan. I've never heard of it being done.
