It doesn't necessarily have to be about war. If I was given the choice to play for Brazil in the World Cup, or Japan, I'd choose Japan. I know if I were to play for Brazil, the chances of winning the World Cup would be greater, but I would prefer to try and win it with a team I love. Tbh, on PS3 football games, I use Japan the most, and I even beat Argentina 1-0 on World Class mode.
But back to the OP's original question, I wouldn't join up to the army, but if I did, I would choose to join Japan in defence of a country I love that has a rich history and culture
