Finland wasn't a part of the Axis powers. They didn't align with the core fascist ideology & were only involved because the Soviet Union attacked them. They didn't even sign the Tripartite Pact, nor were they some puppet state. Only the UK declared war on Finland because they were fighting the USSR but didn't even really fight Finland, it was diplomatic pressure. You'd have to do some *real* weaseling to call Finland an Axis power. Just because they fought on the same side as Hitler doesn't mean they were an Axis power.
