Most Japanese support the creation of a permanent system to let emperors abdicate, a survey showed Monday, highlighting the public's aversion to the government's plan to enact a one-off abdication law applicable only to Emperor Akihito.

In a survey by Kyodo News covering 3,000 people 18 or older, 68 percent of respondents said the Imperial House Law should be revised to enable future emperors to relinquish the Chrysanthemum Throne.

Just 25 percent said that abdication should be legislated on a one-off basis, while 4 percent said Japan should not allow abdication at all.
