Japanese is a bit hard to learn just at the beginning, but once you make a good base of simple prhases, you can improve faster. As Zattou says, the best is to be sure to learn fine the silabaries and then it goes smoother. There are some exercicies for ***s that are good for beginners learning the silabaries, so you can try them bit a bit to make a strong base to go on. Don't worry if it looks hard, you don't need to learn all kanjis that exist, and even regular japanese people have problems for writtings some of them or knowing them. As long you can mantain a conversation fluently, it will be fine :D Even I do mistakes sometimes, and I'm learning it since I was like 12 haha
