I think it's difficult because the number of the character is various and Kanji has many ways to read. Pronunciation is very easy , so if you get to know many Japanese words , you can perfectly guess and listen to Japanese language from TV , Podcast , DVD ...etc. and Russian language is also known as difficult language :)) so in this meaning , it's the same.

do you mean is that japanese is a hard language to learn? i think all language is hard or easy to learn if you have or dont the willingness to learn it. cowboy...

If you want to learn, it should be easy for you. :)
