Comprehensible Input Apps and Sites for Japanese, Compared (2026)

The apps and sites that give comprehensible input for Japanese split into listening and reading. For listening, LingoDew (which we make) plays Japanese YouTube creator videos labeled JLPT N5–N1, with every word tappable. Comprehensible Japanese (now Natural Japanese) makes videos in simple Japanese for learners, sorted from complete beginner up. For reading, Satori Reader has stories written for intermediate learners, LingQ turns any text you import into a lesson, and Tadoku’s graded readers and NHK’s NEWS WEB EASY are free. A practical setup is one listening source and one reading source, each at your level.

We make LingoDew, so we stick to facts you can check on each product’s site or store listing; these were checked on 25 October 2026.

Compared at a glance

Listening input

LingoDew is built for listening practice from native video. It plays a daily selection of Japanese YouTube videos (vlogs, food, travel, daily life), and labels each one N5 to N1 using its timed subtitles: the words, sentence length, grammar and speaking speed. Subtitles are aligned to the audio word by word. Tap a word to open its dictionary card with furigana and romaji, and the video jumps to the moment it is said. Saved words keep their sentence and come back for review on an FSRS schedule. It covers only Japanese and English. You can browse the same videos in a browser by level, starting with N5 videos.

Comprehensible Japanese (rebranded as Natural Japanese) makes videos in simple Japanese for learners. The teachers speak slowly and use visuals to carry the meaning, and the videos are sorted from complete beginner to advanced on the channel’s own scale, not by JLPT level. Many videos are free on YouTube; a membership adds extras. For a total beginner, learner-made video like this is easier to follow than native video.

Reading input

• Satori Reader publishes stories written by native speakers for intermediate learners, with audio, word lookups and explanations. It has web, iPhone and Android versions.
• LingQ is a reading-first platform for more than 50 languages. You read lessons from its library or import your own text, and every word is clickable and tracked from new to known. Because you choose the content, difficulty varies from lesson to lesson.
• Tadoku (from the NPO 多言語多読) offers free graded readers at Level Start and Levels 0–5, and some have recorded audio. You can read them online, download them as PDFs, or watch them on YouTube.
• NHK NEWS WEB EASY (NHKやさしいことばニュース) rewrites current news in simple Japanese for foreign residents and children.

Choosing material that is comprehensible

Comprehensible input only works when you understand most of what you hear or read. Research on reading suggests that comfortable understanding takes knowing about 95–98% of the running words. LingoDew’s corpus shows how far that is for native video: covering 95% of the words in Japanese YouTube videos takes the 8,651 most frequent words (vocabulary coverage study). That is why beginners do better with learner-made or leveled material first.

A practical way to combine these:

1. Reading for vocabulary: Tadoku or Satori Reader at a level where you look up only a few words per page.
2. Listening at one step lower: listening is harder than reading, so watch videos one level below your reading level. If you read comfortably at N4, start with N5 videos.
3. Review only what repeats: save words you meet more than once, and let a spaced-repetition schedule bring them back.
