Are you quoting a round trip? Since this Super Value 75 is the most restricted fare and the month of Feb. is a tourist season for drift ice viewing (you will not be the only one heading to see the drift ice at Monbetsu), I will not expect the fare to go any significantly lower by waiting to see how the fare will fluctuate.

Using Experience Japan Fare on ANA, I am seeing somewhere around US$ 280.00 for round trip Haneda (Tokyo)-Monbetsu round trip in Feb. 2024. Again, with one of the peak tourist seasons (drift ice viewing) I will not expect fares to get any significantly lower by waiting.
