In case you need it, the old method maay work in this game too (i didn't get this game so i can't try):
-uninstall kb971033 and prevent the installation
-find vistalizator and from the same site the jp language pack for your os version, install it and chenge language but don't reboot.
-before rebooting change the registry, places thos lines in a text file named english_over_jap.reg and double click
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Control Panel\Desktop]
"PreferredUILanguages"=hex(7):6a,00,61,00,2d,00,4a,00,50,00,00,00,00,00
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\MUI]
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\MUI\UILanguages]
