Before the war, Germany, Italy and Japan had formed a pact opposing the Communist International, which was Stalin's tool to spread communism throughout the world. Japan actually ended up aiding Germany very little during the war, and decided to disregard the pact and not fight against the USSR (after a short round of skirmishes that saw Japan lose badly). When Japan attacked Pearl Harbor, it was Germany and Italy who declared war on the US as a way of showing solidarity with Japan with the hopes that Japan would aid Germany against the USSR (it never materialized).
