Chika Sensei's Japanese Academy (YouTube)

 Chika Sensei's Japanese Academy is a YouTube channel for learning the Japanese Language. Chika Sensei has been uploading videos for 6 years, and she has just over 600 videos on her channel. 

The videos are pretty much entirely in Japanese, so they are great for learning and studying. Recently, the videos are around 1 to 2 minutes in length. Older videos are slightly longer at around 5 minutes.  She started off introducing a lot of grammar and vocabulary, through useful phrases, in the early days of her channel.  She titled the videos with the Japanese language level of "N5", "N4", and "N3" so that you choose to watch videos at the level you are at.  Later she moved on to videos with questions, and finding the errors in sentences.

Most recently she has been making videos with examples on a whiteboard. It has been a mix of videos about the Japanese Language Proficiency Test (JLPT) grammar and sentences, various spot the error in sentences, and useful phrases. I think this is a very good channel to use for learning, studying, and reviewing Japanese.
