I find focus mode in reelang japanese quite good, it's an app a bit like language reactor but on app. It shows you a video in small parts, always first listening and then you can replay a few times and if you still don't understand replay with subtitles in Japanese (probably enough for you) or translations

Is Reelang the best app to learn Japanese?
It depends on where you are. If you’re starting from zero, a structured course app like Duolingo or Babbel is a good first step. Once you know the basics, from about A2, the hard part is understanding real people, and that’s what Reelang is for: real Japanese videos at your level, with help when you need it. You can use both.
- Real Japanese, not scripts: no actors and no textbook dialogues, just the way people actually talk.
- Always at your level: every clip is graded by level and speaking speed, and the feed adapts as you watch.
- The accents you’ll meet: Standard Japanese, Kansai Japanese, Okinawan Japanese, and Kyushu Japanese.
- Built for listening: most Japanese apps teach words and grammar drills. Reelang trains your ear on real conversations.

How it works
Questions about learning Japanese with Reelang
What is the best app to learn Japanese with real videos?
Reelang is built for it: a free feed of real Japanese videos from native speakers, graded by level, speaking speed and accent, that adapts as you watch.
How does Reelang figure out my level?
It starts you on easier clips and adjusts from what you follow, skip and look up. There’s no placement quiz.
What is the Reelang Japanese video feed?
A TikTok-style feed of real Japanese videos from native speakers, graded by level and speaking speed and tagged by accent. It learns from how you watch and keeps serving clips at your level.
What is comprehensible input?
Comprehensible input is Japanese you can mostly understand, with a little that’s new. Linguist Stephen Krashen argued it’s how we acquire languages, and it’s the idea Reelang is built on.
Reelang takes it a step further with word frequency. It ranks every word in every video by how often it’s used in everyday Japanese, and keeps track of which words you already know. So instead of videos that are only roughly your level, your feed picks the ones made of words you know, plus the most frequent words you haven’t learned yet. Comprehensible input, made for you.
Does Reelang explain the words in each video?
Tap any word for its meaning. With Reelang+, Learner Insights also explain the culture, idioms and slang behind a clip.
A few Japanese words and phrases our explanations cover, from recent videos:
- ハイサイ (haisai): Okinawan for "hello" — said by men; women say ハーイタイ (haaitai)
- ずっしり (zusshiri): "hefty," "weighty" — the satisfying heaviness of something substantial
- お利口 (orikou): "good boy/girl," well-behaved, clever
- ダサい (dasai): "lame," "uncool," "tacky" — the opposite of かっこいい
- 落ちる (ochiru): "to fall for someone" — the same "fall" as in English, but used on its own
Why short videos from native speakers?
Short clips let you hear many more speakers, accents and situations in the same time, so your ear gets used to Japanese as people actually speak it.
How does Reelang know if a video is too fast or too hard?
Every clip is analysed for how it’s spoken, not just which words it uses: speaking speed in words per minute, how often the speaker pauses, how many words come out between pauses, and how much of the clip is speech. With its vocabulary level, that lets the feed match both what you know and how fast you can follow.
What if I don’t know a word?
Tap it to see the meaning. With Reelang+, you also get translations into your own language, and words you look up come back in new clips.
Which Japanese words should I focus on first?
The most common ones. Smart Subtitles show how common each word is, so you can tell which words are worth learning now.
Which levels does it cover?
Beginner (A1) to Advanced (C1). It works best from about A2 upward.
Do I need an account? Is it free?
The Japanese feed is free and you can start without signing up. Reelang+ adds a personalized feed, translations into your own language and words that come back in new clips.
How is Reelang different from a typical language app?
Most apps teach with drills and scripted audio. Reelang trains listening on real Japanese the way people actually speak it.
How much should I watch?
Little and often works best. A daily session you enjoy beats a long one you skip.
About this hub
About comprehensible input in Japanese
What is comprehensible input?
Comprehensible input is language you can mostly follow, with a small amount that is still new. The idea is often associated with Stephen Krashen: people acquire language by understanding meaningful messages, not only by memorizing rules in isolation. Japanese is a particularly good fit, because so much of what matters in real Japanese (politeness, softening, implication) is learned through exposure, not from a list.
Why real reels, not textbook dialogues
Textbook Japanese usually lives in the polite -masu register. Real Japanese shifts constantly. The same speaker changes level when they turn from a colleague to a friend, when they address an older relative, when they talk to themselves. Casual speech contracts no to n, drops particles entirely, and lets the ending carry the tone. Reelang uses unscripted short-form video so those shifts arrive in context, which is where they make sense.
How to use this catalog
Start with your level, then choose a listening difficulty you can mostly follow. From there, browse by topic depending on what you want to work on. If you have solid classroom Japanese and casual speech still surprises you, the missing piece is almost always listening at a level you can stay with. Find topics you would watch in English, and let your ear learn the shifts by seeing them happen.
