Click Language and Region
Click Preferred Language

In search bar type English United States
Click “Next”
Click tick box for “Set as my Windows Display Language”
Click install
Message about waiting for few minutes for this to install
There is a message to Sign Out to install Japanese
sign back in and you are in Japanese
Try and open UEFN if this works it’s a problem with interpreting Windows 11 Japanese Keyboard drivers, but seems to be fixed below
Now open a new Blank project wait for Shaders to compile and set to Japanese
To change these settings, follow these steps.
