Go to Tools (T), Options (O), first tab, second sub-tab, and check the bottom option. However, UTAU might still be entirely in Japanese. If it's a bunch of gibberish symbols, check that you've properly entered the command under Custom Commands in Wineskin. If the blue text under the icon in the top left corner says デフォルト, then that means the text encoding was set correctly! Close the readme, and check the "Do not show" box in the bottom left of the voice check window and close it. Because UTAU is being opened for the first time, it will open a readme.txt and the voice check window. Now, let's select Test Run to make sure it's working properly. On your desktop there will be a couple of files that are meant to be shortcuts, but they don't actually work, so you can delete them.

Set the executable as "/Program Files/UTAU/utau.exe".

The default install location is fine, but from the two radio buttons, choose the one labelled (E).All the text in the installer will be squares, but don't worry, the program itself will not be. Select the UTAU installer you unzipped earlier. Now you can go ahead and click "Install Software". This will make it act as if it's running under Japanese locale.
