Abema TV usually has it live on YT, but I’m rarely up in the middle of the night. So I watch NattoSumo (Japanese feed),
Jason’s Sumo channel for individual bouts or Robert Mensing for the NHK highlights with the English commentary.
these are all channels on YT, Jason and NattoSumo are our up shortly after it ends, the NHK highlights on Robert Mensing’s channel usually get added at about 5pm MDT
