I believe はじめよう.みんな to be the world's first live fully Japanese Domain Name! It is written with the Japanese Hiragana script. みんな is one of Google's new gTLDs icannwiki.com/index.php/.みんな.
Google translates はじめよう to "Let's start with" and みんな to "Everyone" translate.google.co.uk/#ja/en/はじめよう%0Aみんな
One can use the Ideographic Full Stop rather than the ASCII Full Stop as the separator in Internationalized Domain Names ie はじめよう。みんな. This then gives us the rather cool translation to English "Let's start with. Everyone" translate.google.co.uk/#ja/en/はじめよう。みんな
