(From the Logical case for anti-America sentiments topic).
The myths and the realities ... a learning experience for me because I have not looked at the situation before and am making no intellectual pretensions about these roughly assembled notes.
My position would be unapologetically pro self-determination and self-sovereignty ... but that there is no point me picking a fight if they were not able to nor going to back me.
If I was Okinawan, I would be anti-bases.

Once the US bases are gone the economy of Okinawa WILL tank. Property rates will crash and people will flee the island.
I strongly doubt it.
The figures * I read are:
Tourist revenue is 16%
Base revenue is 8% (some say 5%†)
98% of 5,000,000 tourist are from the mainland.
(I would accept this issue is new to me and so that needs qualifying. Average individual income derived from bases is estimated to be 10%)
Extract from that:
a) the long-term social, cultural and environmental costs (say -4%)
Add back
b) the likely existence of a large J-SDF base in its place, say +4%
Plus an increase in J-SDF families, say +1%
It would not be hard to see that 'USA Out' could be made to balance or have little economic impact.
And it would lower the rape case and crime statistics ... both recorded and unrecorded and unprosecuted.
In fact, the Japanese Communist Party calculated that the value of the bases was 420.7 billion yen and the return of all U.S. bases in Okinawa would bring about 2.2 times economic benefits (915.6 billion yen) to Okinawa and demanded that the government make efforts to get these U.S. base sites back to Japan.
Reading further ... one can immediately debunk the myths of the bases being good for the island.
Its nearly 5 trillion Yen investment in the years 1972 - 1996, largely in the form of public works, has done little to create a basis for sustainable development in Japan's poorest prefectrue. Quite the contrary. The agriculture and fishery economy, the distinctive biological and zoological endownment, and Okinawan society have suffered vast social, economic and ecological damage precisely as a result of Japanese-financed construction.

It suggests to me that the money that went into Okinawa did not end up with the Okinawans but the usual depositories such as the large construction and infrastructure companies. Further more, the "leakage", income leaving the island, on tourist spending is around 40% which if plugged and kept on the islands could further balance the economy.
The tourism industry employs many Okinawans, but only rarely in higher-echelon jobs. Most of that industry's profits go to corporations based elsewhere in Japan.
The manufacturing/industrial sector is poorly developed. If the Okinawans were smart (which they are), or at least removed from under the thumb of Tokyo and freed from its bureaucratic bindings, they could replace the US military with some other international presence like a int. university, a proper Free Trade Zone and trade centers inviting more varied foreign investment.
Background
In 1879, Japan forcibly annexed the Ryukyu Kingdom. The main reason for Japan's takeover was the islands' geographic importance for military purposes. Okinawans became second-class citizens within Japan. Some have even argued that Okinawa was in fact Japan's first colony.
In the 1880s, Japan's government was willing to cede part of the Ryukyu Islands to China in return for commercial considerations and even signed a treaty to this effect, but it ultimately failed to gain ratification from the Qing court. Following Japan's defeat in the Second World War, an agreement in 1947 was made with the American Occupation forces that, in return for a short occupation of the mainland, the US could retain possession of Okinawa Prefecture ... indefinitely.
During WWII approximately 20% of the civilian population died (estimated civilian casualties of 90,000 to 150,000), most of the island's infrastructure, historical and cultural assets were destroyed. It was, at the time, largely an undeveloped sub-tropic agricultural society with its own unique culture.
As a result, Okinawa Prefecture was under US military control from 1945-1972. These and many other events belie the Japanese government's claim that it regards Okinawa to be an integral part of the homeland. Between 1945 and 1950, the Americans occupied what Okinawan land they wanted, regardless of whether it had been publicly or privately owned.
Okinawa remains Japan's poorest prefecture, with a per capita income level approximately 70% of the Japanese mainland average and twice unemployment. Post WWII, it has been remade as a service economy, largely serving the bases.
Okinawa Prefecture comprises only 0.6% of the whole Japanese territory and yet is home to 78% of the US Military installations in Japan (20% of the best land of the mainland). Much of the land was forcibly taken from residents. 40% of people who live in the Kadena town think that having military bases in their town is not be a plus for them, only 16% of people do.
The recent development is having a detrimental effect on the environment. Its coral reefs are dying and beaches are being spoilt. Over-fishing has led to the decline of that industry. Highly carcinogenic materials (fuels, oils, solvents, heavy metals and DU rounds) are regularly released during military operations and the people suffer deafening noise from low-flying military aircraft.
Dozens of barrels of the toxic defoliant Agent Orange were buried in the late 1960s beneath what is now a busy neighborhood in the central Okinawa Island town of Chatan, near Araha Beach.
Public works ill-suited to the environment of Okinawa have resulted in the widespread destruction of Okinawa’s mountains, rivers, and sea.
Under the Status of Forces Agreement (SOFA, Article 4), the U.S. is not responsible for environmental clean-up of land or water and host communities are not adequate provided with information on the extent of military contamination.
The islands are home to the worst kept "secret" nuclear weapons.
