Changing language settings on QGIS 3?

Question

I'm using Window 10 Japanese OS. I would like to change the settings (menus etc.) of QGIS 3.0.1 from the default Japanese into English. I tried below but it wouldn't work.

Answer 1

On the same dialog, go to the first tab on the top with the screw driver and the hammer called General. Then, it's the first box. Toggle the first checkbox and choose your flag.

You need to restart QGIS.
