TDR has been losing some support among its local base in Japan since the pandemic, at least the ones who I follow. Obviously Disney is still popular in Japan and the parks aren't hurting for attendance, but TDR has been very bare minimum ever since re-opening in 2020. The continued lack of APs and silence on if they're ever coming back is a big one, plus neutered entertainment and budget cuts hitting seasonal events and food particularly hard.
As a local, I feel like there's very little to keep me coming back to Disney lately. The seasonal events are small and lame (TDS's 25th anniversary in 2021 was a joke and so is this year's TDL 40th from the looks of things). Meanwhile USJ is doing Horror Nights every year (still not 100% back to normal but they're getting there, hopefully this year), just launched a new day parade and has WAY better food.
