In Japanese, nouns and stems of adjectives, verbs, and some adverbs are written in Chinese characters called “Kanji”. This means that you will need to learn Chinese characters to be able to read most of the words in the language.

Kanji characters are relatively easy to read, than writing them. (Actually, remembering how to write complex types of kanji is quite hard even for native Japanese people.)
Especially we are using computers and smart phones which automatically converts hiragana characters into relevant kanji.

Still, learning is fun and there are many opportunities to write the beautiful hand-writing letters in Japanese.
I will not stop learning difficult kanjis!
