There have been predictions for months that the government of Japan is about to ease restrictions, but so far that has not happened. At this point, even if the government does decide to open to cruise lines, I will be very interested to see what rules are set in place by the government regarding testing, masking, and quarantine, including if a close contact tests positive. I don't want to end up put off the ship, or in isolation either on the ship or ashore because someone in one of the excursion buses I was on tests positive. So even if the country opens up to cruising, I still have a lot of questions about how the inevitable positive Covid cases will be handled. I've read the information that was being given to clients who were booked for fall 2022 land trips to Japan (cancelled now) on Tauck, and it was not reassuring reading.
DH and I are currently booked on a March 2023 Tokyo to Tokyo cruise we very much want to go on, but the devil's in the details.;
