Japan's Emperor Akihito (2nd R) walks with Empress Michiko, as the Imperial family members follow towards a crowd of guests during the annual autumn garden party at the Akasaka Palace imperial garden in Tokyo October 31, 2013. A Japanese lawmaker handed Emperor Akihito a letter on Thursday expressing fear about the health impact of the Fukushima nuclear disaster, breaking a taboo by trying to involve the emperor in politics. Taro Yamamoto, who is also an anti-nuclear activist, gave Akihito the letter during the garden party, setting off a storm of protest on the Internet from critics shocked at his action. Akihito, who turns 80 in December, fills a purely ceremonial role and remains above the political fray. REUTERS/Kazuhiro Nogi/Pool (JAPAN - Tags: ENTERTAINMENT POLITICS DISASTER ROYALS)
