>>2005623(me)Updated because I found this list of stations that JR Hokkaido supposedly wants to close
https://news.mynavi.jp/article/20230626-jrhokkaido/Don't know if it has been officially confirmed, but it seems to track so far. It does point to local trains only going up to Bifuka and the remainder being either Limited Express only(and making them stop at Yuchi) or at best only having a commuter local train between Wakkanai and Toyotomi/Horonobe.
