Osaka-4

I'm using a Japanese keyboard model SK-8115. Stage 1 was not working for me as I had the same issue. - My work-around was to go to "Regional and Language options" Selected the tab "Languages" and clicked on "Details" (Also in the tab "Advanced" I selected "Japanese") - In the "Settings" tab I changed the "Default input language" to: [Japanese - Microsoft IME Standard 2002 ver. 8.1] - Than changed the "Installed services" to Japanese Keyboard with also above [Japanese - Microsoft IME Standard 2002 ver. 8.1] selected Restarted and all works splendid for me. No need for any drivers or such, think you just need the Japanese IME to be installed. Hope that it helps or at least direct you to a solution
