The language is real easy... actually it might be even easier than many european languages. There is no plural, no past tense, no future tense, not even masculin and feminin. Heck, they don't have gender issues at all with the language :joy:
The two alphabets and the kanji symbolic writing systems are hard though IMHO... or maybe not hard, it's just that you have to retain at least 20.000 different of these: 漢字
So speaking is easy, reading/writing is a challenge...
