Yes, yes! DD is graduating this year from university. She really wants to visit Japan, so we are going this July. First time to this beautiful country. Too little time yet too many things to do! Planning a trip to Japan is more challenging than planning FPs for WDW! Your little man definitely has picked one of the best places to celebrate his high school graduation!! I am skipping Hiroshima this time, but going to Sapporo instead to escape from the heat for a few days before going to HK (my hometown). This way I would have an excuse to go to Japan again to see Hiroshima.
I agree that Japan is very expensive. I have been telling DH numerous times that this trip is going to be quite costly. Hope he wouldn’t have the payment shock after DD and I return from the trip.
