Need NHK WORLD JAPAN free app on FireTV help to activate while watching

We, as XFinity customers, lost programming and channel 265 fully removed as of March 31st, 2026 from our NJ tv viewing area. Here in Ocean County, Monmouth County areas.

We are truly bummed but have an inquiry to have an option to receiving it.

The free app thru Fire TV viewing of all the programming for NHKWorld Japan  would include Grand Sumo highlights as well? Needs some help how you physically get it activated on the screen while viewing? Please advise.

Very dissappointed with NHK World Japan pulling this. Thank you in advance.
