Hello friend, would you be willing to write up a step by step on how you got the game to run?
Well, I may not be able to exactly re-trace the steps I took to run it, since they may not work on your system, but if you can provide at least the name of the OS you're running I may be able to help you as much as I can
I'm a new user, so I can't post links in my messages yet, but if you're running Ubuntu, Debian, Fedora or mac OS, you can just get the download instructions from the official WineHQ website to get it from your package manager.
I'm using Arch Linux, however, and the version that was supplied in pacman didn't work properly for me, so I built it from source myself. Instructions on that can be found on the same WineHQ site's wiki, page "Building Wine". Do not forget to check out chapter 4, "Shared WoW64", to build a version that can run x64 applications as well.
When you have Wine and you have created your prefix, you may also need Winetricks script, which is pretty easy to find. I don't remember which utilities did I install, but among them was definitely Japanese font support, I can only tell you that much.
However, since the game is made in NodeJS and is running in a glorified web browser, you may try running it natively by installing NW.js. Although from what I understand 4.0.6 has been packaged differently and the game folder doesn't contain necessary files to make it a one-step process (seems to be missing a Manifest file or smth), so I can't help you there
