Japan and the US

It’s insightful to learn about Japan’s role with the US government. It’s true that we cannot “blame” Japan for accommodating and shaping to whoever the US president is. Whether it be Trump or Sanders, Japan is going to constantly adapt to who we elect as president - objectively, of course. Following this idea however, it seems that not all Japanese people were in favor of Japan’s tendency to support the US presidents and their ideals. The movement Anpo Toso, otherwise known as the student movement against the Alliance, that took place during the late 1980s in hopes of limiting Japan’s reliance on the US. Because of this movement, there was light shed on Japan’s dependency on the US. I’m wondering if the Anpo Toso was shocking to Japan’s society. Was Japan aware of others’ disapproval?
