Japanese is easy to learn, but difficult to master. I thought it was ok at first, but I felt very confused when I kept learning. Grammar is very complicated, and it's annoying to remember. But looking at this language mainly depends on subjective efforts, and the difficulty lies in verbs. Freshman mainly studies languages, and sophomore begins to learn other aspects of Japanese, such as listening, conversation, grammar, translation, writing, literature history, literature reading and so on.
