Depends on what you mean by "publicly funded sports stadiums". Stadiums that can only be used by a handful of local professional athletes? Hell no. Stadiums that are part of local public infrastructure are a different story. Facilities that can be rented in-full or in-part for a nominal fee by any resident in the community, and/or that during unused times are a center for community fitness? Hell yes. Every city or ward in Japan has some kind of community center, and most of them have gyms and other fitness facilities, and overall they compare well to for-profit gyms -- which, admittedly, are absolute shit in Japan across the board, public, private, or otherwise[1] [1] The average gym in Japan consists of approximately ten million treadmills and one squat rack, the latter having a reservation system, and being about as easy to book as an appointment with Elon Musk.
