Not on the topic of language, but a good cultural channel (Jun's Kitchen)
JunsKitchen is a YouTube channel run by a Japanese cook (with three adorable cats who watch him cook) that, apart from showing bike rides throughout the Japanese country side, shows you how to cook food. He usually does Japanese recipes like Tofu and Sushi Balls but I have seen him make fancy cat food and Western dessert as well. This video covers Popcorn Rice, which is one of his easier recipes (although do be careful with boiling oil!). I wanted to share this to anyone who is curious about Japanese food and/or want to make it themselves.
Enjoy the culture and いただきます！
There's also Rachel and Jun, which is Jun and his wife Rachel. They do a lot of cultural stuff, both just about Japan in general, but also cross-cultural things, things that are weird about Japan its culture for Americans/vice versa, since they are themselves a multi-cultural couple.
I found Rachel and Jun when I started Duolingo Japanese beta. Back then it was mobile only, had no notes and you basically had to divert to Google Translate, Wikipedia, YouTube and more to actually learn anything. I discovered the video where they work on R and L together. Jun's Kitchen is the one I keep coming back to now.
