Which Japanese island is over 80,000 square miles in area?

I am living on Honshu, Tokyo. Honshu is bigger than Hokkaido, but maybe due to projection in Mercator maps it is hard to tell. Hokkaido is 83450 km^2 (not miles^2). So, quite a bit smaller.

Japan has alot of beautiful things to see!! everything seems so delicate. Do you really have to take your shoes off before entering a door?? airways wondered that!!!
