Kimigayo is Japan’s national anthem. Its lyrics date to the Heian period and the melody was adopted in 1880; it became the official anthem after 1999.
Japan's Diet has passed a law criminalising publicly damaging or defacing the Hinomaru flag to prevent discomfort and protect national symbols. Violators face up to two years in prison or a 200,000 yen fine. The measure is championed by Prime Minister Takaichi but faces constitutional criticism over free speech concerns.
