Id be very careful with the Japanese share market.
Right now it is ticking along with all that newly printed money.So far it has decreased the value of the yen[making your investments worth less] but the Yen is NOT the international currency. Its a dangerous game and your investments could easily crash and burn along with your crystal ball.
Every one knows about China,but theres talk that ,not just yet,but INDIA is the one to keep your eye on.....and I wouldnt be so quick to discount BRAZIL
