あかね的日本語教室, otherwise known as Akane's Japanese Class, is a popular YouTube channel produced by a Japanese teacher named Akane. This channel is targeted towards intermediate and advanced learners. However, Akane mentions that this channel is also accessible to beginners who want a bit of a challenge. The difficulty comes from all the videos being entirely in Japanese. The subtitles at the bottom of the screen are in Japanese, and include furigana over more difficult kanji. There are also closed captioning subtitles that can be turned off and on, with an impressive number of languages covered — 15!
The videos on this channel are very educational while also entertaining. The topics surround learning Japanese, travel around Japan, everyday life in Japan, and more. An example of Akane's videos that Japanese learners may find most useful are "[Business Japanese] Basics of telephone correspondence" and several interviews with non-native speakers living in Japan and studying the language. Each video lasts about 10-15 minutes in length, and they go by quickly. Because Akane speaks slowly, it's easy to follow the dialogue.
