Get the Game

So first thing is, you’ll need to download the game. If you’re in Japan, all good! If not, you’ll need to find the APK or use QooApp which is a Chinese app that lets you download region locked apps.
As for iOS, you’ll need a Japanese account to get the game. Please google on how to make a Japanese iTunes account as there’s plenty of guides out there. Steparu’s method might be a way.

Once you start, the game will guide you through a tutorial, pay attention!
After that, feel free to browse the menu items at the top to see what the moonrunes say.
