We went out trying to buy a pair of new joggers for me, but being Sunday morning none of the likely shops were open, so we went back to the 'cell'. We could see police everywhere, and it turned out there was a parade in honour of WWII, so we didn't go out just in case there was some trouble.
At checkout time we took the train to the airport and flew out of Hong Kong. The flight arrived in Japan after 5pm. Got on a train into town and with help from others on the train, got off at the right station. We had to change underground stations, and certainly would not have been able to get there without help from a lovely Japanese lady. When we checked in we were very impressed with such a good hotel.
