How to install a Japanese Win7

Greetings,

I lived in Japan for 2 years, and got myself a Dell Studio 1557 laptop while I was there.
Needless to say the OS was in Japanese (Windows 7 Home Edition), which wasn't really a problem as I do have a level of understanding of Japanese and I've got used to it by now (I bought the laptop around March 2010).
However, right now I'm in need of giving my laptop some mainteanance and thus I'm thinking about reinstalling the OS, and that's where I'm facing an issue, because despite having some knowledge on Japanese, I'm not confident I'll be able to understand much whenever the boot/set-up screen shows up.

My main question is if the steps to reinstall Windows would be exactly the same as if I were working with an English version.
Are there, perhaps, any screencaps out there I could follow to avoid making any mistake?

Thanks in advance.
