I saw earlier a newsflash on Hirohito's death. Here's the Japanese version.
The entire video is in Japanese.
The person that appears first in the video is former Japanese Prime Minister Keizo Obuchi (deceased). The (then) Chief Cabinet Secretary appeared in a live TV newsbreak to announce to Japan their Emperor's death. After his announcement is over (or the TV cut the feed), we were shown a title card with the words "His Imperial Majesty The King has Died" in Japanese, while a special "newsbreak chime" rings in the background.
The video then cuts to studio, where the anchor basically repeats the thing Keizo Obuchi said.
