My impression is that because Ospreys showed signs of control problems, the population didn't fancy having them flying continuously over them and their houses. Seems reasonable to me
Sorry, but I think you're clutching at straws here! I think you have conflated your own impression of the Osprey, drawn from little relevant evidence, with the well-known and possibly well-justified antipathy of the local population of Okinawa to the overwhelming American presence on the island.
Your original post:
Residents of the island of Okinawa, Japan have complained about Ospreys since they first arrived on the large US base there, not least because there have been several crashes.
I have shown to be false. There has been one crash, offshore, in which no-one was injured.
Your attempt to draw support from the local press:
Besides the crash there have been other incidents, as in this link:
https://mainichi.jp/english/search?q=okinawa+ospreys
Shows possibly one other incident (an 'emergency landing'), and a lot of references to the December 2016 incident - some indeed using that incident as the justification for protesting further Osprey deployments (though in Tokyo, not Okinawa) - with non-specific references to 'other accidents', which are presumably referring to accidents during testing in the USA.
As the Osprey has been deployed in Okinawa for over 10 years there will be a number of minor incidents on record, but there is only one accident. The aircraft has a sound safety record in the region, despite a difficult gestation in its early development. The press coverage does not seem to present any evidence of any other accidents apart from one in Australia. The combination of this and the 2016 accident off Okinawa, appears to constitute 'a series of accidents' for their purpose, which is the closure of Futenma MCAS.
Now, as I say, the locals may well have good reasons to resent the Americans and to wish they weren't there (well, those who aren't employed by or because of them, anyway) but for you or the Okinawans to suggest the Osprey is a credible reason for this is laughable!
