Since HOST_LC_ALL was introduced, Proton starts Wine with LC_ALL=C, which ignores LANG set via launch options. Games that previously worked with just:
HOST_LC_ALL
LC_ALL=C
LANG
LANG=ja_JP.UTF-8 %command%
no longer pick up the locale.
To work around it one needs to set both variables explicitly:
HOST_LC_ALL=ja_JP.UTF-8 LANG=ja_JP.UTF-8 %command%
Which now again starts wineserver with Japanese locale and make the games that depends on it work.
