How do I change the language on iCloud Web from any language to English?
well, hope its helps, when you open a browser and type icloud.com, then suddenly its appear on other language e.g.; Japanese (in my experience), then just click the sign in button (i think anyone would recognize one), then it goes to other page that require you to type an id, right? then just simply click the words/sentence under the check box (that should be "Create Apple Account") then it goes to a new box that require for us to like a register new id right? just ignore other blank boxes and go straight to the language box and change it to your country language, then just simply refresh the web browser. and that should do it. hope it helps.
