Just to barge in on that question regarding the Japanese tour dates in 1991. Doc McGhee had set them up at the time the band was still touring New Jersey and effectively would have wanted for them to tour up to that point. Richie's quote on WWWB: "People came to us and asked 'can you do another 70 shows?' and we went 'we gotta stop, man!' because everybody was just a mess."

Connected to the New Year's Eve show (which was similar to the '88/'89 one), he had then added a few more dates in Japan because, unlike Europe, the band had not gone back there yet for a second time on the NJ tour. I read some quote that the band didn't find out about those dates until after what they thought had been their final shows in Mexico and were (probably) contractually obliged to play these shows, so they did.
