Emperor Naruhito of Japan has been enthroned in a short ceremony in the Pine Room of the Imperial Palace in Tokyo, dressed in a copper robe - a colour only an emperor can wear. Emperor Naruhito officially began his reign in May after the abdication of his father, the then-Emperor Akihito. But, after a series of traditional rituals inside the imperial palace in Tokyo, his ascension has now been formalised. Annemarie Evans spoke to RTHK's correspondent in Tokyo, Julian Ryall, about Tuesday's events.
