Are you in need of some new, authentic learning material for your Japanese studies? Created by NHK, Japan's national broadcasting organization, NHK for School is like an online school where you can study various subjects with relatively simple Japanese.
While these videos are made for native Japanese speakers, the language used in them is generally not too advanced.
On the home screen of the website, you will find programs on a variety of subjects, including Japanese literature, history, science, and sociology. These programs are constantly updated with new videos and materials. If the content on the main page does not match your Japanese level, click "TV Program" or "Short Video" at the top of the home screen. On these pages, you can select TV programs or short videos based on the Japanese school level that they are intended for. These range from different elementary school grades up through middle and high school, so you can definitely find content that fits your level of Japanese.
While these videos are made for native Japanese speakers, the language used in them is generally not too advanced, and most higher level kanji feature furigana readings. Each video also has a transcript. Transcripts do not always coincide with the narration, but you can review a lot of the vocabulary and grammar used in the video. These programs also have supplemental materials which help you test your comprehension. For example, the program「おはなしの国」, which introduces Japanese folk stories, has supplemental readings and comprehension quizzes for each section. If you're in need of something new for your studies, give NHK for School a try!
