The price of Singapore kerosene-type jet fuel during the two month period of October and November 2015 averaged US$58.37 per barrel, which accounted for 7,077 yen in the average exchange rate of 121.24 JPY/USD during the same period.
As a result, with reference to the fuel surcharge benchmark list for FY2015 in Japanese yen, this corresponds to Zone B of fuel surcharges. From February to March 2016, it will range from 300 yen on a Japan - Korea ticket to 7,000 yen on a Japan - USA ticket per person per sector flown, on tickets for travel originating in Japan.
For itineraries originated outside of Japan, YQ will be zero.
