That's a very simplistic view of the criticism, and I completely disagree with it. Just because I think Japanese is complicated (not "unnecessarily", that of course doesn't make sense when talking about a natural language) doesn't mean I think it should be simplified, nor that I can't back my claims.

Take hiragana for instance, it consists of 46 characters (versus 26 for the latin alphabet). The latin alphabet is way more efficient than hiragana because we compose sounds instead of syllables: ta is t+a, whereas in hiragana あ doesn't appear in た. Then you add katakana and kanji, and it just becomes impossible to think of Japanese writing as not complicated.
