To what extent is Japan controlled by the United States?

This needs to be analyzed from economic, military and diplomatic aspects.

Economically, in the last century, the Japanese generally believed that Sony was the greatest company in the world. Results On 20 18, we looked at the composition of Sony shares, and the largest shareholder was American capital. The United States does not even need the help of a capital consortium to deal with Japan. The president directly announced that Japanese cars would increase taxes or be banned from entering the market. If we lose more than 30% of Japan's foreign trade in the North American market, the Japanese stock market will definitely collapse, and a large number of related enterprises, steel, machinery manufacturing, energy and other industries will lay off employees. In that year, GDP growth was negative and the Prime Minister would be ousted. (Refer to Japan's Lost Thirty Years)

Militarily, it does not count the local forces of the US military, the naval fleet and the surrounding military bases, but only the military strength of the US military bases stationed in Japan. If the Japanese Prime Minister dares to declare independence from the United States, the Japanese parliament will be gone within half an hour. In addition, the Japanese navy and air force are heavily equipped with American military equipment. Referring to the case that the US military left a back door for Iraqi equipment, Japan really dared to rebel. Whether these weapons can be used is a huge problem. (refers to the location of the US military base in Japan, and important locations in Japan have been hit and covered)

Diplomatically, as long as the United States announces that it will no longer protect Japan, Japan, sandwiched between China and Russia, will lose its right to speak internationally. You don't even need to go to war. Because of the daily military exercises on important shipping routes and the lack of external resources and energy imports, it is only a matter of time before Japan is trapped and killed. (Refer to the situation in Japan after the Battle of Okinawa in World War II)

Finally, the United States has been infiltrating a large number of intelligence personnel in Japan since World War II, and it also has privileged protection. There must be American agents in the Japanese government, and every move is actually strictly controlled.

PS: Finally, suppose an extreme case. Even if Japan can make all American troops stationed in Japan disappear, those Japanese and American equipment will not be affected, China and Russia will not make moves, and even nuclear weapons around the world will disappear. Just as American military forces in South Korea, Singapore and Guam can fight against Japan, the navy and the triangle encirclement.
