The packaged land tour I booked, ends on 16 Jan at 13:05. While the whole tour group returns back to Singapore via direct connecting flight from Haneda, I'm going to stay a few more days in Tokyo on F&E. But I couldn't get a departure flight from Chitose - Haneda around that timing. Only managed to get the 17:35 departure flight. I have 4hrs to kill while waiting for the flight. Pls advise if there's anything I can do around Chitose Airport?
