Each country has its own rules for holding state funerals to honor distinguished national figures. State funerals have been held for past presidents and royalty such as former U.S. President George H.W. Bush and former South Korean President Roh Tae-woo, while the latest overseas example is that of Britain's Queen Elizabeth II.

In Japan, there is continued opposition to the state funeral for former Prime Minister Shinzo Abe slated for Sept. 27, including protests outside parliament and elsewhere, alongside a petition calling for its cancellation.

Some Japanese social media users have taken to using the hashtag "real state funeral" to refer to the ceremony held for Elizabeth on Monday, highlighting what they see as the contentious elements of the state funeral plan for Abe — a political figure with a controversial legacy.
