You might want to reconsider this cruise, then, if you're so worried about that scenario. My wife and I have been looking forward to this cruise for several years now. We've already bought our round-trip airfare, so in case the cruise gets cancelled, we would probably end up doing a land-only vacation. For now, we're remaining upbeat about our cruise. Since we've been on 10 cruises together now, we're all too familiar with the possibility of changes and cancellations, but if we allowed uncertainty over these things to dissuade us, we'd never vacation at all. Uncertainty and risk are just a part of life, which we acknowledge and accept. Japan is more open now than it's been since early 2020, so that's one of the reasons I'm sanguine about our chances.
