Japan on Sunday ended a 150-day mourning period for the late Empress Dowager, posthumously known as Empress Kojun, who died June 16 at the age of 97, Imperial Household Agency officials said Monday.

The Emperor, Empress and other Imperial family members will until June next year refrain from attending in-house events in the Imperial household such as the Nov. 23 Niiname rice-harvest festival, the officials said.

The Imperial family will make regular public appearances.
