"Woah! I didn't expect it to start working already. I usually have to switch over to my Japanese curated YT channel, but this even overrides my english accounts. Great for limiting distractions since majority of the english leisure content won't show up with the entension filter active no matter which channel it's on."

Frequently asked questions

Here's what NihongoTube users often want to know.

How does JLPT estimation work?
NihongoTube uses the transcript of a video to analyze the vocabulary, grammar and speech rate. These factors are then compared against known JLPT level data to estimate the video's difficulty level.
How does filtering work?
NihongoTube uses video titles and metadata to determine whether a video is Japanese and employs some clever tricks to get around things like YouTube's automatic translations.
What browsers are supported?
NihongoTube is available for Chrome, Edge, Brave, Firefox and other Chromium-based browsers.
Can I use NihongoTube on mobile?
Yes! NihongoTube works on Firefox for Android. Simply install Firefox on your Android device, then install the NihongoTube extension from the Firefox Add-ons store. Mobile support includes core filtering features optimized for smaller screens.
Can I customize what gets filtered?
Absolutely! The extension comes with extensive customization options accessible through the popup menu. You can toggle filtering for comments, specific types of recommendations, JLPT badges, and more. There's also a master toggle to quickly disable all filtering when needed.
