In all my trips to Japan, I have only ever had one meal in the $100 price range and that was a birthday celebration for some dear friends. Beyond that, I don't think I ever spent more than $50 per DAY on meals and more often than not it was much less. I never made a reservation other than the aforementioned birthday dinner at Azalea in Kyoto. Before my first visit I worried a bit about my limited Japanese and finding decent meals. It was unfounded and I never went hungry. Enjoyable food is one of the better reasons to visit Japan.
