A lot of people think so, too. I personally find Korean pronunciation challenging... maybe because they have a lot of vowels. xD I feel them!!! There are a lot of things I can't explain in my mother tongue (Cebuano) because it's either we use the Spanish-borrowed ones or English. It's so difficult to explain Cebuano since I never formally learned it. Tagalog, maybe, but I almost never use it. I'm actually more confident with using English to Tagalog.

It's the Kanji (Chinese characters) that stops me from learning. They're too many and they're read differently depending on the sentence or situation. T_T Though I have to agree, speaking can be easy since they're mostly syllabic. Thanks!!! My listening isn't that bad though (thanks to anime... lol).
