Agree with Crackers but they may just avoid the Kyushu part and offer a different area. Giving an option to cancel. Maybe the area of Kyushu you go to is not impacted at all. So you see, you really have to call or wait for them to contact you with firmer details of any impact.
We just completed this trip, Northbound, from Kyoto to Tokyo, and had no changes to our itinerary due to the earthquake problems that Japan experienced. Our tour directors briefed us before we left Kyoto, and we were again re-assured by the ship's captain that there would be no changes to our itinerary as planned by Tauck.
