Kanji can make a two-minute Japanese article feel like a locked door. The best Japanese reading apps lower that barrier with furigana, but the strongest tools also let you decide when readings appear.
Furigana should support comprehension without replacing kanji recognition. Beginners may need readings on nearly every unfamiliar character, while intermediate learners often prefer help only for unknown words. These 2026 options differ sharply in how much control they offer, so the right choice depends on your level, device, budget, and study habits.
What adjustable furigana should do
Furigana is the small hiragana text shown beside or above kanji to provide pronunciation. It helps you read words before you fully recognize their characters, which makes authentic Japanese less intimidating.
However, simply having furigana isn’t the same as having adjustable furigana. A useful reading app should let you change how much support appears. Ideally, you can show readings for every kanji, hide readings for familiar characters, or reveal them only when a word causes trouble.
The most useful furigana setting is one that changes as your kanji knowledge improves.
Look for more than a show or hide button
A basic reader may offer one global toggle. That can help, but it doesn’t reflect how learners actually read. You might know the kanji å¦ but still need help with an unfamiliar word such as å¦è²». Word-level or familiarity-based controls handle this difference better.
Also check whether the app supports clickable definitions, audio, grammar notes, and saved vocabulary. Furigana solves pronunciation problems, but it doesn’t explain every sentence.
Use readings as temporary support
Reading every word with furigana can make a passage feel easy while leaving kanji recognition unchanged. A better routine is to begin with full support, then hide readings for familiar characters and restore them only when needed.
This gradual reduction works especially well with short articles and graded stories. You can focus on meaning first, then reread the same passage with less assistance.
Best Japanese reading apps with adjustable furigana in 2026
The table below separates clear furigana controls from apps that provide reading help without a verified reader-wide adjustment system.
| App | Best for | Furigana control | Platforms and offline use | Current plan structure |
|---|---|---|---|---|
| Manabi Reader | Fine-grained control | Familiarity, flashcard status, always show, or always hide | iPhone, iPad, Mac; offline-friendly | Free core, premium subscription |
| Satori Reader | Guided stories and listening | Adjustable support based on known characters and reader settings | iOS, web, and other mobile access; offline with Pro | Free sample access, Pro subscription |
| Todai Easy Japanese | News and travel reading | Furigana is available, but detailed adjustment isn’t clearly documented | iOS and Android; offline mode | Free with in-app purchases |
| Kanshudo | All-in-one study | Reading assistance in its Reading Corner, rather than a clearly verified global furigana system | Web-based study platform | Free and paid features vary |
Manabi Reader offers the clearest control for learners who want furigana to respond to known vocabulary. Satori Reader is the better fit for structured content. Todai is useful for accessible news, but confirm its current furigana options before paying.
Manabi Reader: best for fine-grained control
Manabi Reader is the strongest match when adjustable furigana is your main requirement. It focuses on reading Japanese through web-style content and EPUB books, with tools for bookmarks, vocabulary, kanji lookup, and reading history.
Set readings by familiarity
Manabi Reader can show furigana based on your familiarity with each word. Available behavior includes hiding readings for familiar words, showing them only for words in flashcards, and choosing always-show or always-hide settings.
A public discussion of Manabi Reader’s furigana settings describes this flexible approach. It is more useful than a single beginner or advanced mode because your knowledge is uneven. You can recognize common kanji while still needing help with specialist vocabulary.
The app also supports EPUB reading, which makes it suitable for learners who want to work through Japanese books rather than only built-in lessons.
Free core, Apple-only access, and local data
Manabi Reader’s core reading features are free. Premium access is needed for some advanced features, and word tracking is limited as a preview without payment. The companion Manabi Flashcards app has a limit of 10 reviews per day without a subscription.
At the time of checking, the App Store listed pricing around ¥1,300 per month or ¥6,000 per year, with student discounts also shown. Prices, trials, and discounts can change, so check the current Apple listing before subscribing.
The main limitation is platform support. Manabi Reader is built for iPhone, iPad, and Mac, so Android users need another option. Offline reading is supported, and the developer says reading data stays on the device or in personal iCloud storage. Manabi Flashcards data is stored on Manabi servers, while Anki flashcards aren’t sent to those servers.
Satori Reader: best for guided stories
Satori Reader is one of the most polished Japanese reading apps for learners who want content with built-in explanations. Its articles and story series include audio, translations, vocabulary help, grammar notes, and comprehension support.
Adjust furigana as your kanji improves
Satori Reader lets you adjust furigana settings and use known-kanji information to reduce readings. Its system is lesson-focused rather than a simple free-form slider, but it still gives you a practical way to read with less assistance over time.
The app’s presentation engine adapts Japanese text to the learner’s reading ability. You can open a sentence, check a word, listen to native audio, and continue without moving between several separate tools. LanguaVibe’s Satori Reader review covers its inline notes, vocabulary support, and furigana options in more detail.
The free tier includes unlimited access to the first two episodes of each series, along with selected special content. A Pro subscription unlocks the full library, which currently contains more than 1,200 episodes.
Subscription, offline access, and privacy
Satori Reader’s official App Store listing supports iPhone and iPad access. The Google Play listing provides an Android option, and a subscription includes web access across supported devices.
The current pricing page lists Pro at $9 per month or $89 per year. Pro also includes offline access. Those figures can change, and introductory offers may vary by storefront, so confirm the latest price before purchase.
Satori Reader is a strong choice if you prefer guided stories over importing your own books. It is less flexible than Manabi Reader for completely custom reading material, but its explanations make difficult sentences easier to understand. Users can close an account and request deletion of personal data through the service’s account or support process.
Todai Easy Japanese and other useful options
Not every app with furigana offers the same level of control. Some tools prioritize accessible content, dictionaries, or study review instead of detailed reading settings.
Todai Easy Japanese for news and travel
Todai Easy Japanese provides Japanese news and learning content for a wide range of levels. Its free app includes in-app purchases, and the official store information advertises offline reading, which helps when you are commuting or traveling without reliable data.
Todai is available on iOS and Android. Store listings show several premium packages, but prices differ by region, currency, and storefront. One Google Play listing showed options around $8.99 for three months, $14.99 for one year, and $21.99 for lifetime access at the time of checking.
The important limitation is furigana control. Furigana is available, but current official descriptions don’t clearly verify a setting that adjusts readings by familiarity or JLPT level. If that feature decides your purchase, test the current version first. Google Play also states that the app doesn’t share data with other companies and encrypts data in transit.
Kanshudo, Readlang, and Yomitan
Kanshudo combines kanji, vocabulary, grammar, reading, and review tools. Its Reading Corner provides translations, audio, grammar information, and kanji details when you select words or sentences. Read the Kanshudo review if you want an all-in-one study system rather than a dedicated reader.
Readlang is better for intermediate and advanced learners who want to import or browse native content. Its inline dictionary helps you save unfamiliar words while reading, but it isn’t primarily a furigana-adjustment app. The Readlang review explains how its reading workflow compares with more guided tools.
Yomitan is different again. It is a browser dictionary and lookup extension, not a standalone reading app. Furigana depends on the website, browser setup, or reading environment, so it shouldn’t be your first choice if you want one dependable furigana control panel.
Choose by learner level and study goal
Your ideal app should make reading challenging enough to build skill, but manageable enough to keep you reading.
Beginners who need steady support
Satori Reader is the easiest starting point for beginners who know kana and basic grammar. Short episodes, translations, audio, and grammar notes reduce the need to search elsewhere.
Todai can also work if you prefer news-style content and want an Android option. Manabi Reader is a good choice when you already have EPUBs or online material and want more control than a fixed lesson system provides.
Intermediate learners building kanji independence
Manabi Reader is the best fit for intermediate learners who recognize common kanji and want furigana to disappear selectively. Set readings to hide for familiar words, then keep them available for new vocabulary.
Satori Reader suits learners who want a clear progression through stories. Its notes are useful when your problem is sentence structure, not only kanji pronunciation.
Advanced readers, travelers, and offline users
Advanced learners often need fewer readings and more control over source material. Manabi Reader works well for EPUB books and offline study on Apple devices. Readlang or Yomitan may suit readers who already understand most sentences and mainly need fast word lookup.
For travel, Todai’s offline mode is practical. Still, download articles before leaving a connection and check whether the features you need remain available without an account or active subscription.
A reading routine that prevents furigana dependence
The app matters, but your reading settings matter just as much. Use this four-step routine:
- Read once with your normal furigana setting and focus on the overall meaning.
- Hide readings for kanji you recognize, even if the word feels slightly slow.
- Look up only words that block comprehension, then save useful vocabulary.
- Reread the passage with less support and listen to the audio if it is available.
Keep a short record of words you repeatedly miss. If the same kanji appears several times, add it to a focused review system rather than leaving furigana on forever. A separate kanji tool can complement reading practice, especially when recognition is your main weakness.
Prices and features change during app updates, and storefronts may show different plans. Check the current official listing, privacy policy, and offline terms before subscribing.
Conclusion
Manabi Reader is the clearest pick for adjustable furigana, offline reading, and custom Japanese material on Apple devices. Satori Reader is better for guided stories, explanations, and listening practice, while Todai Easy Japanese fits learners who want news and offline access across iOS and Android.
Choose furigana settings that reduce support as your recognition improves. The best Japanese reading apps don’t remove every difficult kanji; they give you enough help to keep reading until fewer readings are necessary.
