Quoted By:
Nip reading student here, it takes dedication and patience so if you have neither quit while you still have the chance.
Japanese is composed of Kanji (漢字 chinese characters), Hiragana (ひらがな cursive like script), and Katakana (カタカナ blocky like script). You MUST learn to read hiragana and katana first, preferably practice writing it too as it helps memorization.
After this go to memrise and learn the first ~1,000 jōyō kanji meanings (not reading just symbol to english word meaning). This will put you in middle school level understanding of Kanji characters which will be enough for the next part.
Now go back to memrise and study N5 vocab + N5 grammar and work your way up to N4 vocab + N4 grammar. At this point you will be able to sorta understand half of what nips write, you should also be able to go to japan and get by on your own asking for directions or basic help.
From this point on you must finish learning the other ~1,000 jōyō kanji and work your way up to N1 vocab + grammar. This will give you high school comprehension of reading material and if you can ace the N1 JPLT test you can also even apply to japanese collages now.
I must warn you learning japanese takes a fucklong time, expect to get to N4 level japanese reading comprehension after a year if you study 2 hours a day like me. Good luck 先輩
