My tutor just started her own YouTube channel. She wanted to try something other channels weren’t doing, so if you’re interested in checking out something a little different, I recommend it 
Her target audience at the moment is beginners (N5). She covers mostly verb and adjective conjugations, but she’s planning on expanding as she continues to work on it. Seems pretty useful for review (especially for the upcoming JLPT!)
Definitely check it out and consider subscribing, she’d really appreciate it!
