Buying Japan version camera

Hi! I'm seeking an advice regards weather to buy a Japanese version SLR-camera (Sony Alpha) which only display Japanese language on screen and Japanese manual.

My Japanese are only very basic and I'm wondering is there any software that could be use to install/convert the language from Japanese to English?

I wish someone would have answer for it.. many thanks.

There shouldn't be any problem.
I recently bought a new Canon digital camera and found it switches easily between Japanese and English. If you have problems doing it, you can have a camera dealer do it for you.

English manual is available here and probably on other Sony worldwide websites as well.

Thank you for your reply. However, the Sony Alpha doesn't has the language switching programme installed. The only language show is Japanese.
