Japan was threatened militarily by the possibility of a Communist government in Vietnam

Japan was not directly threatened by a communist government in Vietnam. The main reason why the United States involved itself in Vietnam in the 1960s was because it feared that if Vietnam became communist, then surrounding countries would quickly follow. This was known as the domino theory, where the spread of communism in one country would lead to the spread of communism in neighboring countries. Additionally, American businesses in Vietnam were also threatened by the Communists, which contributed to the U.S. involvement.
