I do find it interesting that some in Japan seem to jump on any chance to protest the US, especially in regards to Okinawa, and especially with the Osprey...but Japan have ordered the Osprey, and seemed just fine with opening the Fuji run MV-22 depot with much fanfare earlier this year. Yes I understand the politics.

Forgot who came up with the quote first, but something like "they would protest the Marines having a bake sale on Okinawa...."
All the best to the families involved in this case.
