'The Yasukuni shrine was established shortly after the Meiji Restoration as the Shokonsha, then was renamed Yasukuni in 1879. During the Allied Occupation after World War II, the U.S. authorities ordered that the Shinto religion be separated from the state. Yasukuni became a private shrine.
A majority of the Occupation staff favored burning down the shrine because they considered it to be a symbol of militarism. General Douglas MacArthur, the supreme commander, however, asked a panel of Christian ministers for their view.
In a written reply, they said the shrine should be preserved. "Every nation has the right and duty to pay respects to the people who died for the nation," their report said. "This must be equally true for either the victor or the vanquished." Destroying the shrine, they said, "would leave a dishonorable stain on the history of the United States military."'
it was in 1974 when the ruling party ldp passed the yasukuni jinja ho-an, a bill to nationalize the shrine and enjoy full government support. american occupiers wanted to burn it down, but macarthur stopped it. it didn't pose a problem post-war until 1974 because it was a private shrine, without formal government recognition. moreover, it was not a cemetery. ashes of the dead were returned to family and relatives.
the problem with yasukuni started in 1974 at japan's ascendancy on the economic world map (coinciding with u.s. losses in vietnam and eventual withdrawal in 1975). there was a sense of national pride and power, and the idiots at ldp had to re-vitalize the jap spirit, taking a stab at u.s. shame in vietnam. americans should have bombed the shit existence out of japan when she had the chance in ww2.
btw, hirohito refrained from visiting the shrine after the war.
i expect this ongoing yasukuni drama to end with a big bang from nukes coming from north korea.
