Subway Haneda Airport Terminal 3

Relatively comfortable

I think this Subway is relatively new. There is a sign outside about it opening in March, presumably March 2026. Its great to have another affordable eating option at Haneda AIrport. It is located on the 3rd floor of Haneda Airport Terminal 3, but a little out of view - in the area of the elevators that lead to the bus stops, before the check-in area. There is a sitting area and its relatively comfortable.
