Japanese radicals opposed to the monarchy vandalized several imperial institutions around the country as Emperor Hirohito lay in serious but stable condition. Horse manure was scattered outside a burial mound in Nara that is reputed to contain the remains of Emperor Jimmu, the legendary first ruler of Japan. In nearby Kyoto, a smoke bomb exploded outside the tomb of Mutsuhito, the Meiji emperor and Hirohito’s grandfather. And small smoke bombs went off at two Tokyo subway entrances near the imperial palace. A police official said the explosions and vandalism were apparently the work of radicals opposed to the extensive media coverage of Hirohito’s illness.
