Hi. I'm planning to take a trip of around 3 months in Japan from December to February. My flights are booked so I can't really change the length of the trip. I want to travel all over Japan from Sapporo all the way to Nagasaki. I'm just wondering if approximately $3500 will be enough money for food and sightseeing (accommodation, transportation and flights are all paid for separately) in Japan for a time period of 75 - 90 days? Thanks everyone who replies!
