Is it difficult to learn Japanese or is it easy? The answer is that it is both difficult and easy. Japanese pronunciation is rather easy. Japanese consists of 46 syllables that can only be pronounced in one way. Almost all of those syllables exist in English and other European languages so you can master the pronunciation rather quickly and people will often understand you when you read Romanized written in our alphabet. Japanese also use thousands of English loan words. Once you master these you will have immediately have access to a huge vocabulary.
The challenge when learning Japanese is the grammar, the levels in the language and not least the writing. Written Japanese consists of three writing languages. Hiragana and Katakana has one character per syllable where Katakana is only used for loan words. Those two writing languages are quite easy to learn but Kanji, the third writing language, consisting of a couple of thousand Chinese characters is much more challenging.
At CEI students can study Japanese from beginner level to advanced level. However many schools ask that beginners have at least a passive knowledge of Hiragana and Katakana when students start a long term course in Japan
