Emperor Akihito is abdicating on April 30, with his era of "Heisei" coming to an end. The new era takes effect May 1. Chief Cabinet Secretary Yoshihide Suga said Monday the name draws from the 7th century poetry collection "Manyoshu."
Suga said that Prime Minister Shinzo Abe would explain the meaning of the name later at a news conference. It is believed to be the first time the era name, or "gengo" has been taken from a Japanese document, a break from more than 1,300 years of using Chinese classics.
Japan's government is holding top-secret meetings to decide a new era name for soon-to-be-emperor Naruhito, who will succeed the Chrysanthemum throne from his father May 1.

Prime Minister Shinzo Abe's government later Monday will unveil the era name, or "gengo," for Naruhito's reign.
It comes a month ahead of the switch to allow the government, businesses and other sectors time to adjust to the change that still affects many parts of Japan's society, even though the system is not compulsory and the emperor has no political power under Japan's postwar constitution.
