Structure for website names...and which character set to use?

はじめまして. This is my first post on this forum and I hope to take a lot away from it. I'm starting a website about general Japanese media and I decided on calling it 'completejapan', but it got me wondering how I would exactly write that. Looking in a few dictionaries and online, I found many variations of 'complete' - some in kanji and some in katakana. For a website name, which would I use? I will explain more if I'm not explaining myself well enough, but I hope I did!

I'm learning Japanese as a hobby at a club at school. I appreciate that this forum is probably more advanced, but I really am quite passionate about the language. Thank you.

I would expect it to be something like 「総和」 （そうわ）
To the best of my knowledge kanji and kana are both suitable for a website name.

The character set used will be determined by the words (unless you deliberately wanted to write it a certain way for effect). 総和 seems to mean "summation", though. I don't know how one would go about putting "complete Japan" into Japanese. It depends on just what you mean by that.
