Japan has forest coverage of 67%, which is very respectable. New Zealand has 31.87%. Next 3 countries after New Zealand are Germany, Canada and United States.
Canada is funny though - with so much arctic and prairie land it throws off the calculations. That's not necessarily due to deforestation however (even though there is a ton of that going on).
