Hey,
most of these are on the number 3 recovery disk. If you put it in the drive it’ll warn you about it being disk 3 and ask if you want to open app’s instead. All the drivers are there and applications which include hotkeys, jog dial etc. Just about all of them will install in english. I think there’s one or two in Japanese but they are not critical and install anyway - you just click on the next button and let it go.
You do have to install in a certain order though…...
The only one that’s a pain is the Japanese power panel as the profiles (battery saver, high power etc) are in Japanese. I have an english on for the U3 if you need.
