There used to be a US military base in Subic and Clark at Luzon.
There are still many US military bases in Japan. Okinawa’s Kadena, Tokyo’s Yokota, Kanagawa’s Zama, Nagasaki’s Sasebo etc. This is a remnant of occupation after the Pacific War. But it is not necessarily humiliating. Because postwar Japan was able to concentrate on economic activities by outsourcing military power to the United States. By the other hand, The United States was able to continue the alliance relationship between the two countries while deterring Japanese reinforcement strengthening.
However, US soldiers cause serious incidents in Japan occasionally. Especially in Okinawa Prefecture. Okinawa was occupied by the United States until 1972 even after the war. And there are still many US military bases there. In Okinawa, traffic accidents and women violence by US soldiers are repeated. Of course most of the US soldiers are harmless, but the incident that had not happened without a US military base gives a bad impression.
Also, the overhead of Tokyo is under the control of Yokota Base, and the route that Japanese aircraft can fly is largely restricted.
However, if Japan asks for the withdrawal of the US military, Japan will be required to take self defense. Therefore Japan need to promote the SDF to military, and heavily armed them. Of course it costs huge costs. In addition, the conscription system may be inevitable. And when the war broke out they will be dispatched to the battlefield, since they are soldiers.
How to get along with US military bases is a painful issue.
