Japan buyers of Dark Souls 3 currently have some issues after purchasing Global Keys to open the game. The package install size shows only 200MB and it isn’t playable, as the 200MB represent bonus soundtrack to Dark Souls 3. If you are from Japan and have the same problem, please then try our recommendations:
Change Language in Your Steam Client to Japanese and press install the same 200MB file. After this actions, said file will be allocated and you will download necessary 17GB of data. Also there is one problem with this fix, as it works only once you download and run the Dark Souls 3 – the game will be presented in Japanese language, thus, Global Key paying doesn’t matter anymore.
Also try to open Games Library and go to Dark Souls 3 properties. Try to change game language to English as we suggest you to backup your game files before doing this action. Changing your language can delete game files as you will need to redownload all new.
