Great news everyone! I created a free ProtonVPN account via their website, downloaded and then installed their VPN client application, launched the application, selected one of their free servers in Japan, was assigned a Japanese IP address and was then finally able to access this Japan-only, exclusive (Not for export outside of Japan) game's Steam page instead of seeing the usual, "This item is currently unavailable in your region" Steam message!
So if you want to access the Steam page for any Japan-only, exclusive game like "Winnning Post 10 2025" you now can, thanks to ProtonVPN!
Domo arigato, ProtonVPN-san! English not supported. Perhaps sometime in the future a few fans of this game who live outside [Or maybe even inside] of Japan, can start with an English Interface translation (Easiest and least expensive). If a fan base further develops and increases among the English speaking Japanese expatriates, "Natural born citizens of a country outside of Japan who are of Japanese descent (heritage)" and/or students of the Japanese language (Can be anyone regardless of race, ethnicity, color, creed, ... etc), perhaps English Subtitles can be added by fans of this game (Most difficult and most expensive). See my explanation about translation.
06/25/24 - Update: Don't want to wait for a proper English Translation of a non-English supported game but want to play the game now? You can try to use the freeware "LunaTranslator" combination text hooker (text grabber) and language translator application (GitHub page | Download page) to machine translate or AI translate the game's native text into English (Note: Machine translation is 1:1, word for word translation. Some ideas may get "lost in the translation". AI translation attempts to mimic a natural speaker's translation of a language into English (I haven't tried this method yet)).
See the verbose "How to" demo video posted by "Daiya" on YouTube (Note: From her dialogue in the video, Daiya seems to be a teenage girl, so try to bear with the "quirkiness" of her dialogue with the viewer [you]. She set LunaTranslator to use AI translation [See the improved English translated, purple text in the screenshot]). 08/18/24 - Update: If you're having problems with how to set up LunaTranslator before launching a VN then watch "superange128"'s finely detailed tutorial video on YouTube! I have set the link to advance to the precise pos in the video where he begins to explain how to set up LunaTranslator.
In the past, I personally have used the AGTH (Anime Games Text Hooker application with the Atlas Japanese-English translator application) to try to play untranslated Japanese H-games with machine translation and just discovered this combination text hooker and translator application that supports AI translation (An improvement over machine translation) so, if you have any in-depth questions then it's best to visit the dev, "HIllya51"'s Q&A page on GitHub.
