They’re posting these the same day now?

Looks like:

• at 12:30pm ET they start streaming the most recent highlights at https://www3.nhk.or.jp/nhkworld/en/live_tv/
• when they're done streaming at 1pm ET they make them available at https://www3.nhk.or.jp/nhkworld/en/shows/sumo/
• then after another delay (of a day or two?) they're put on youtube.

In all cases they "disappear" after a week or so.
