Well since I studied a little of Mandarin Chinese before taking Japanese courses! Sometimes the on'yomi was the same in both languages like 来 is pronouncing ライ et lai in chinese so it helped me ! But apart from that ,to learn Kanji I listen to Japanese music and I sing with the lyrics in Japanese lol Is there something specific you love about Japan like an idol or anything of that kind! Well I read something about my favorite Japanese idol ,it helps me understand a little more the language ! I remember well the Kanji ! BUT I also take a piece of paper and write the Kanji I learn many times until I can remember the meanings ,the 音読みand訓読み ! Last year I knew 400 kanjis , right now I've reached 1200 kanjis! READ READ READ is the only way you can remember them! I would've loved giving you some sites where you can learn them but it's French... I hope I helped you !!
