A gratuitous house party is roiling Japanese politics, landing the Prime Minister in deep trouble. Shotaro Kishida, the 32-year-old scion and political heir apparent of Japan’s incumbent leader Fumio Kishida, has been fired from his post as his father’s executive policy secretary after images of him using the Prime Minister’s official residence for a private party sparked public outrage. Photos released by the Shukan Bunshun weekly magazine last week showed Kishida’s son posing with relatives on red-carpeted stairs like how newly appointed Cabinet officials would.
