All of those aren't Japanese... The first one is Chinese, the second is Korean and the third is Indonesian.
You can tell it's Japanese if it has Japanese kana, such as;
あおい, that is the first alphabet of Japanese (hirigana) and there is of course katakana: アオイ
Chinese letters are like this
你好
Korean is written like this;
ㅗ디ㅣ
of course Chinese letter are used in Japanese (called kanji).
But in Chinese, they are used all the time.
To taste 'real' japanese ramen, just go to a ramen bar. And to know if it's really good, you'll just see a bunch of aisan/japanese people around it, or otherwise, ask an aisan/japanese freind to take you to get some ramen!
And by the way, the mi goreng noodles aren't even ramen! They're indonesian noodles!
