There are a lot of materials to learn Japanese.
I just found nice one and wanna share it with you!
It’s called 彩り（いろどり/IRODORI）.
You can study with those pdf files, which is including audio as well.
I think that 初級１ is for JLPT-N5 level/みんなの日本語１, and 初級２ is for JLPT-N4 level/みんなの日本語２.
So, you can start learning Japanese with them. Or you can review if you’ve already done with those levels.
Please try them for free.
