Not knowing where you are flying from, so not sure about your situation. You are planning to have a dinner at high end sushi restaurant on the day of arrival at NRT. Are you flying in from Europe, U.S., Oceania, etc.? After the long flight some people find the evening of the arrival to be very tired and sleepy due to jet lag. Spending money on high end restaurant on the day of arrival, do you think you will be in the condition to fully enjoy the meal?
