Japan's Emperor Naruhito and Empress Masako will visit Britain as state guests in late June, marking the first state visit by a sitting emperor since his father Akihito's in 1998.
Japan's former Emperor Akihito turns 90, after having spent another peaceful year with his wife, former Empress Michiko while continuing to reflect on war and peace and those impacted by natural disasters, according to the Imperial Household Agency.
Crown Prince Fumihito, the younger brother of Emperor Naruhito, says on the occasion of his 58th birthday that a review of official duties is needed as imperial family members age or leave the royal house.
Japanese Crown Prince Fumihito and his wife Princess Kiko will make an official visit to Vietnam in late September on the occasion of the 50th anniversary of diplomatic relations between the two countries, the Imperial Household Agency says.
