I would make a back up ADR, but don't cancel your Japan ressie. We were there last week -- it was supposed to have re-opened on 8/21. We had made a back up ressie. About 2 weeks before our Japan ressie, I got a call from WDW. They left a vm at my home. It took a few days before I finally connected with someone. The person I finally talked to was very nice and helpful. I explained that I had made a back up, so I was fine. She said that they really felt bad about the mix-up and she saw that we were eating at Epcot restaurants a couple other times and would we like VIP viewing for Illuminations one night. I said, sure. So we got it for the night we were eating at Rose and Crown. Well, we checked in for R&C and I explained that I was supposed to get some certificate for an Illuminations thing. They had to find the manager to get that for us. Then they seated us -- at the absolute best spot on the patio for Illuminations. The manager came over and gave me the VIP card but said that if we wanted to just stay at our table, we were welcome to do that (our ADR was for 7:40). We opted to stay and have a nice seat for Illuminations and it was great. It would have been cool to do the VIP viewing thing, but who knows how many people they were going to be crowding into the area.
