How to change Oracle SQL Developer Interface from Japanese to English

Do you want to use Oracle SQL Developer in English but you’re running Japanese Windows OS? 

Here’s what you need to do to make Oracle SQL Developer display English texts in menus.



  • Open the file ide.conf using any text editor.  You can find this in

<SQL Developer installation folder>\ide\bin

  •  Add the following lines to the end of the file and save it:

AddVMOption -Duser.language=en

That’s it! You can now start OSD as you would normally do and you will get all User Interface texts in English.
