Ok now here's a bunch of resources for those who are curious
I really don't like Duolingo by the way (edit: or many textbooks for that matter)
Tofugu This has articles on grammar and culture and Japanese in general, starting with a
hiragana and
katakana guide which is where I think you should start
Maggie Sensei and
Wasabi JPN are two other really great grammar sites I recommend
Mangajin was a magazine that used manga to dissect sentences while also explaining cultural aspects, I personally really like its system, and even though it's slightly dated (90s) I still think it's very useful
Minato JF has online courses that can take you up from absolute beginner to an intermediate level (B1), and if your native language isn't English this supports several other languages too (Portuguese, Vietnamese, etc.)
Marshall Yin combines a forum with a set of lessons that go all the way up to JLPT N1 (
explanation), good for those that like structured learning and being with a community of other learners (curated and managed by one person who's more than happy to help those that need it)
Japanese Ammo with Misa and
Miku Real Japanese are two great YouTube channels to check out, they also explain grammar and give example sentences and all that good stuff, see for yourself
Now, how to find native speakers to practice with? Both HelloTalk and Tandem are built exactly for this, and I highly suggest you try them out
And for reading practice, I uploaded the first 13 editions of
Yotsubato! on my Google Drive, and Animal Crossing is also really good, since both of them have furigana (something you'll soon learn to love)
Sorry for so many of them, this is something I'm passionate about
and I want to give you options
Everything I linked is free, and there's plenty of other resources I haven't listed here that's out there waiting for you
頑張ってね!Good luck!
