Anthems are designed to inspire patriotism to one's country. No surprise there.
Most national anthems are about a nation; some (e. g. 'God Save the Queen' ) are about its monarch.
""Kimigayo" (君が代, Japanese pronunciation: [kimiɡajo]; "His Imperial Majesty's Reign" )
is the national anthem of Japan. The lyrics of "Kimigayo" are the oldest
among the world's national anthems, and with a length of 32 characters,
they are also the world's shortest. The lyrics are from a waka poem
written by an unnamed author in the Heian period (794–1185),"
"Japan's national anthem is deemed the world's most controversial due
to its post-war history. Schools have been the center of controversy
over both it and the national flag. The Tokyo Board of Education
requires the use of both "Kimigayo" and flag at events under their jurisdiction.
The order requires school teachers to respect both symbols or risk losing their jobs.
In 1999, several teachers in Hiroshima refused to put up the anthem
while the Hiroshima Education Board demanded that they do so.
As the tension arose between them, a vice-principal committed suicide.
A similar incident in Osaka in 2010 also occurred, with 32 teachers
refusing to sing the song in a ceremony. In 2011, nine more teachers
joined the rebellion, along with another eight in 2012.
Hashimoto Toru, the mayor of Osaka, slated the teachers as "[i]t was
good that criminals [teachers] who are intent on breaking the rules
[of not singing the state anthem] have risen to the surface [public]".
Some have protested that such rules violate the United Nations Universal
Declaration of Human Rights and the "freedom of thought, belief and conscience"
clause in the Constitution of Japan, but the Board has argued
that since schools are government agencies, their employees have an
obligation to teach their students how to be good Japanese citizens.
Teachers have unsuccessfully brought criminal complaints against
Tokyo Governor Shintarō Ishihara and senior officials for ordering
teachers to honor the Hinomaru and "Kimigayo". After earlier
opposition, the Japan Teachers Union accepts the use of both the flag
and national anthem; the smaller All Japan Teachers and Staffs Union
still opposes both symbols and their use inside the school system.
In 2006, Katsuhisa Fujita, a retired teacher in Tokyo, was threatened
with imprisonment and fined 200,000 yen (roughly 2,000 US dollars)
after he was accused of disturbing a graduation ceremony at Itabashi
High School by urging the attendees to remain seated during the
playing of the national anthem."
