Kanji is the most common stumbling block for Japanese learners. It’s easy to see why: there are 1,945 Joyo kanji, hundreds more non-Joyo kanji that are still very commonly used, and yet hundreds more kanji that are used in people’s names. And each of these intricate little characters has a specific order in which the strokes must be written, probably has multiple readings, might have multiple meanings, and can be mixed and matched with many other kanji to create compound words (熟語 : jukugo).

Basically, there is a reason that Japanese students are still studying kanji even in high school, and that reason is that kanji are as difficult as they are many.
