Is $1000 dollars enough to visit Japan?

Is $1000 really sufficient to fund a trip to Japan? Considering the exchange rate, accommodation costs, transportation expenses, and the high price of dining out in Japan, wouldn't it be wiser to budget for a higher amount? Or perhaps, if we're frugal and plan our itinerary carefully, can we stretch $1000 to cover all the essentials of a fulfilling visit to the Land of the Rising Sun?
