After its traumatic defeat in the Second World War, Japan turned its back on military power and concentrated instead on economic growth. Japan’s alliance with the US was enough to protect it from threats in the Cold War. But times have changed. China has now overtaken Japan in both economic growth and military spending.

Japanese Foreign Minister Taro Kono announced last month that Tokyo would be seeking a greater role in world affairs, including boosting its military.
