How to read Japanese on iPhone Safari (2026): a learner's mobile workflow
You're on the train. You have ten minutes and an iPhone. There's a Japanese article you've been meaning to read, maybe NHK News Web Easy, maybe a tweet thread, maybe a blog post a friend sent the link to. You open Safari, scroll to the top of the page, and realize the popup dictionary workflow you use on your laptop is not quite the same here.
This is a real gap. Reading Japanese on iPhone Safari is not the same as reading Japanese on desktop Chrome with Yomitan, and pretending otherwise wastes your reading time. But there is a workable mobile workflow once you know what iOS actually gives you, which Safari extensions are worth installing (yes, some exist), which dedicated dictionary apps fill the gaps the browser leaves open, and how to connect the words you find on iPhone to a spaced repetition system back on your computer.
This post is the version of that guide I wish I had when I switched my afternoon Japanese reading from laptop to phone. It assumes you already know what kanji and furigana are, that you have an intermediate-or-above reading habit, and that you're not trying to learn Japanese from zero on a touchscreen.
Before the workflow, the honest framing. Safari on iOS supports browser extensions, but the API surface is more restricted than desktop Chrome's. Yomitan and Mouse Dictionary, the two extensions most desktop immersion learners use for Japanese, have not been ported to iOS Safari. This is not a failure of those tools. It is the design scope of Apple's WebKit on iOS, and porting a desktop extension to that surface is a separate engineering project that not every team has taken on.
The good news is that one of the major desktop Japanese-reader extensions, 10ten Reader, has been ported to iOS Safari. The bad news is that the desktop hover-lookup model (point at a word, see the definition instantly, save in one click) still does not have a direct equivalent on touch. iOS Safari extensions for Japanese tend to use drag-to-lookup, tap-to-lookup, or paragraph-process patterns instead of hover.
The mobile workflow is built out of different pieces: the iOS Look Up dictionary, Live Text, Safari's built-in page translation, a small set of Safari extensions built specifically for Japanese (10ten Reader, Nihongo, Furiganify), and dedicated iOS dictionary apps. Photo lookup of printed text is also possible and surprisingly useful once you have the right app for it.
Those pieces, used together, are usable. They are not as fast or as integrated as the desktop popup-dictionary stack. They are enough for the kind of reading you actually do on a phone: short bursts, casual content, articles in transit, social posts. As of May 2026, here is what each layer is for.
The fastest way to read Japanese on iPhone Safari is to use what Apple already ships, before you install anything.
iOS Look Up. Press and hold any Japanese word in a Safari webpage, drag the selection handles to capture the word or phrase, and tap "Look Up." iOS surfaces the definition from its built-in Japanese dictionary, plus translations, search results from the web, and app suggestions. The dictionary is JP-EN at the headword level and good enough for short text, common words, and most everyday vocabulary. It handles kanji compounds reasonably well once the selection is clean. You can customize which dictionaries iOS prioritizes in Settings > General > Dictionary. Turn on the Japanese-English entries and turn off languages you don't read, so Look Up doesn't dilute results with your other preferred language entries.
Live Text. If the Japanese you want to read is in a picture, a screenshot, or a photo of a sign, Live Text can extract it. Long-press the image inside Safari, choose "Select Text," and copy the recognized characters. From there you can paste into Look Up, into a dictionary app, or into Translate. Live Text added Japanese support with iOS 16; if you're on an older device, verify support before relying on it. Vertical text was not supported when Japanese support first shipped, so for tategaki content (novels, manga, formal signs) results can still be hit-or-miss; horizontal text works well. The same trick works on iPad with the same gesture, and on a Mac with Apple M1 or later running a recent macOS, which makes it possible to grab Japanese text from any picture you have synced through iCloud.
Safari page translation. Tap the aA icon in the smart search field next to the address bar at the top of the page, then "Translate to English." Safari translates the entire webpage in place. Page translation supports a long list of source and target languages including Spanish, French, German, Italian, Portuguese, Russian, Chinese, Korean, Arabic, Thai, Indonesian, Turkish, Dutch, and Polish, so the same trick works for any reading you do in those languages too. This is bulk translation rather than learning (you lose the reading practice if you flip the whole page), but it is useful for skimming a long article first, then switching back to the Japanese view for sentences you want to read properly. The translation is roughly DeepL-grade for short text and weaker on technical or literary writing.
A small set of Safari extensions has been built specifically for learning Japanese on iPhone. The three worth knowing about as of May 2026 are 10ten Reader, Nihongo's Safari extension, and standalone furigana extensions like Furiganify.
10ten Reader for Safari. If you've used 10ten Reader (or its predecessor Rikaichamp) on desktop, the iOS Safari version is the closest mobile equivalent to that workflow. After installing the app from the App Store and enabling it in Settings > Safari > Extensions, you activate the extension from the Safari menu on any webpage with Japanese text. The interface uses a draggable "10." circle that you drop onto a word to look it up, instead of hover-on-desktop. The extension covers JP-EN definitions, kanji breakdowns with educational and Kanji Kentei levels, pitch accent information, romaji display, and vertical-text support. It requires iOS 15 or later. The dictionary data updates automatically. Free on the App Store. This is the most desktop-faithful Japanese reading extension on iOS Safari today, and the closest answer for "how do I get Yomitan-style lookup on my iPhone."
Nihongo Safari Extension. Nihongo is a long-running iOS Japanese-learning app, and its companion Safari extension adds furigana or romaji above kanji on any webpage, then lets you tap any word for a definition right inside Safari. After installing Nihongo from the App Store and enabling the extension in Settings > Safari > Extensions, tap the extension icon next to the address bar on any page with Japanese text. The extension processes the page and renders phonetic reading guides above the characters. The furigana-rendering and in-Safari lookup features are part of Nihongo's Pro subscription. For intermediate readers who can read most kanji but want a backup on rare characters, this is a smooth way to keep furigana visible without leaving Safari. Advanced learners often turn furigana off entirely except on names and obscure terms, and the extension lets you toggle that per page.
Furigana-only extensions. Smaller Safari extensions exist that focus only on adding furigana to Japanese webpages, without the broader dictionary-app integration. Furiganify is a lightweight one that has been around for years and is free with in-app purchases for some advanced features. Quality varies across the category, updates and bug fixes can lag iOS releases, and a few are paid up front. Check the App Store reviews and last-updated date before installing.
Clipping and paste-to-lookup. Nihongo also has a clipping feature: paste Japanese text from any source into the app and each word becomes tappable for a definition. This is useful for longer articles where reading word-by-word in Safari is slow. Copy the whole passage, paste into Nihongo, then read with each word ready to expand. The clipping feature also works for text you grab from a picture with Live Text, which closes a small loop between manga panels, signs, and webpages.
What none of these Safari extensions do, as of 2026, is replicate the full desktop Yomitan workflow of hovering over a word for an instant popup with definition, reading, and one-click save to flashcards in a single tool. 10ten Reader comes closest on the lookup side but does not push the saved word into a spaced repetition system. Nihongo gets you furigana + tap-to-define but the save loop lives inside Nihongo itself rather than connecting to your existing study tool. Verify pricing, subscription terms, and app availability against the App Store before installing. The iOS Japanese-dictionary scene moves faster than desktop, and apps come and go.
When iOS Look Up isn't deep enough (uncommon kanji compounds, technical vocabulary, idioms, JLPT-level reference) and Safari extensions don't give you the depth you need, a dedicated dictionary app fills the gap. Three are worth knowing about. Confirm current pricing on the App Store before installing, because mobile dictionary apps shift faster than desktop. Some are completely free, some have a free version with in-app purchases designed to unlock extra features, and some are paid up front.
Shirabe Jisho. Free Japanese dictionary built on JMdict data, no subscription, no in-app purchases. Strong on JP-EN headwords, includes example sentences, conjugation lookup, and a clean iOS interface. Like most JMdict-based dictionaries, it categorizes words as common, uncommon, or rare, which helps you focus your study on vocabulary you're more likely to encounter in everyday Japanese. Good default for English-speaking learners who want one solid free dictionary app.
imiwa? Long-standing free Japanese dictionary for iPhone and iPad. Kanji lookup by radical, SKIP, handwriting, and component. Useful when you have a kanji in front of you that you can see but can't read, and you need to find it without typing. The app also covers basic kanji study material: stroke counts, radicals, and on-yomi / kun-yomi readings for each character. For intermediate learners who want to read kanji more confidently, leaning on radicals and stroke counts to recognize structure is one of the cheapest gains you can make on mobile.
Yomiwa. Free app to download, with optional paid upgrades. Yomiwa's focus is OCR and photo lookup: point the camera at printed Japanese text (a menu, a sign, a manga page, a book) and Yomiwa recognizes the characters and offers lookups. The base download includes OCR and the core dictionary. In-app purchases unlock Yomiwa Pro and the Outlier kanji dictionaries (Outlier Essentials, Outlier Expert), which add etymological depth on kanji. Check the App Store for current in-app purchase pricing.
For most intermediate learners, Shirabe Jisho plus iOS Look Up covers the dictionary side of mobile reading. Add Yomiwa if you read a lot of printed text in transit, want to look up signs in Japan, or like to study from real-world picture material. Add imiwa? if you frequently hit kanji you can't input.
The single feature that turns iPhone into a serious mobile Japanese reading device is photo lookup. With Live Text on the built-in side and Yomiwa on the dedicated side, you can read Japanese from any picture: a sign on the street, a manga panel, a printed book, a menu, a friend's screenshot. Take the picture, or open one from your library, and the workflow is the same.
With Live Text, the path is long-press the picture, tap "Select Text," and the recognized Japanese characters become selectable as if they were a webpage. From there you can tap "Look Up" for the iOS dictionary, or copy and paste into a dictionary app. Live Text is free, ships with iOS 16 and later, and works on iPad and on a Mac with Apple M1 or later as well, so the same picture you OCR on your phone is usable on your other devices.
With Yomiwa, the path is more integrated: open Yomiwa, point the camera or pick a photo, and the app overlays definitions on the characters in real time. This is the closest mobile equivalent to a desktop popup dictionary, applied to physical text instead of webpages. The ability to look up words by taking a picture of Japanese text simplifies the process of understanding unfamiliar vocabulary while you read, and turns idle moments (queueing for coffee, riding the train, walking through a station with Japanese signage) into vocabulary acquisition opportunities in real time.
Use Live Text as the free default and Yomiwa when you read printed Japanese often enough to justify the in-app upgrades.
Here is the part most iPhone-Japanese guides leave out. Mobile reading is good for discovery: finding new words while you read in transit, on a break, before bed. Mobile is not great for retention. Tapping a word, reading the definition, and putting your phone away is not how vocabulary sticks. Without a system that brings those words back at the right intervals, most of them fade by next week.
Spaced repetition is the standard fix. Effective spaced repetition systems adapt to your progress, so words you haven't mastered come back more often than the ones you already know, and the schedule lengthens automatically as a word sticks. A flashcards-based SRS turns the scattered words you find on Safari, in pictures, and in dictionary apps into a deck that schedules itself. Many modern SRS systems, including the one inside immit, also do not penalize you for missed study days. Skip a day and the next session just picks up where you left off, instead of stacking punishment on top of the backlog. That flexibility matters when you study from a phone in pockets of free time rather than in long focused sessions.
The cross-device pattern that works:
On iPhone Safari, use Look Up, 10ten Reader, Nihongo's extension, Yomiwa's photo lookup, or a dictionary app to read short pieces and find new words. When a word feels worth remembering, capture it: screenshot the sentence, paste the word into Notes, or save it in whichever dictionary app you're using if the app has a save feature.
Back on your laptop, open the captured words in a tool that handles both lookup and spaced repetition in one place. Read the sentence again with full context, look up the word in a desktop popup dictionary, and save it to a flashcards deck that will schedule reviews for you.
Review on your laptop a few times a week. Reviews stick better on a real keyboard, in a focused session, than on a phone between other things.
immit is the tool I use for steps 2 and 3 on desktop. It runs as a Chrome extension, with an optional desktop app on Mac, Windows, and Linux. Hover any Japanese word on a webpage, see the definition right there, click the bookmark icon to save it, and the word enters immit's built-in FSRS review together with the sentence it came from. No account is required for lookup, save, and review, and everything is free; syncing between your computers is free too with an optional account.
To be plain about it: immit does not have an iOS app today. What it does have is a web app you can open in Safari to review your saved words on the phone (free, with an account). So the workflow above is honest. Use the iPhone tools for mobile reading, bring discovered words back to a laptop where the popup-and-SRS loop closes, and review them anywhere, including on the phone.
This mobile workflow is built for intermediate-and-above learners of Japanese who already read at home and want to reclaim phone time for the same habit. Advanced learners get the most from it: you already know the kanji you don't know, you already read enough to surface useful vocabulary at a steady rate, and the bottleneck for you is not "find a dictionary app" but "make the words I find stick." Photo lookup turns subway signs and convenience-store labels into reading practice. Page translation lets you skim long articles before deciding which paragraphs are worth slow reading. 10ten Reader's draggable lookup makes Safari-based reading actually viable for sustained sessions. Spaced repetition on the desktop side closes the loop.
If you're earlier in your Japanese learning and you're still working through grammar lessons in a course-style app, mobile reading is a complement, not a replacement. Read short, easy material (NHK News Web Easy is the canonical first stop), use furigana extensions liberally, and don't worry yet about building a serious flashcards system. Save that workflow for when you're reading multiple short articles a week without bouncing off them.
No. Yomitan is a desktop browser extension built for the desktop Chrome and Firefox Web Extensions APIs, and Safari on iOS does not support it. The closest mobile equivalents are 10ten Reader for Safari (drag-to-lookup, free on the App Store, the most desktop-faithful option), Nihongo's Safari Extension for furigana plus tap-to-define, and dedicated iOS dictionary apps like Shirabe Jisho for deeper lookups.
Does immit work on iPhone?
Not as an app. immit's lookup ships as a Chrome extension (with an optional desktop app on Mac, Windows, and Linux), and you can review your saved words on iPhone through immit's web app with a free account. If you want the immit workflow on mobile, the recommended pattern is to read on iPhone Safari with iOS tools (10ten Reader, Nihongo, Look Up), bring captured words back to immit on your laptop, and review them wherever you are.
What is the best Japanese dictionary app for iPhone?
For most intermediate learners, Shirabe Jisho is the default recommendation: free, built on JMdict, includes example sentences, and has a clean iOS interface. iOS Look Up handles short queries without an extra app. Imiwa? is the better choice when you need to find kanji you can't type, and Yomiwa is the right pick if you want photo lookup of printed Japanese text.
Can I copy Japanese text from a picture on iPhone?
Yes, using iOS Live Text. Long-press the picture, tap "Select Text," and copy the recognized characters. Live Text added Japanese support in iOS 16 and works on iPhone, iPad, and on a Mac with Apple M1 or later. You can paste the copied text into Look Up, a dictionary app, or Translate. Vertical text was not supported when Japanese first shipped, so results on tategaki content can be hit-or-miss; horizontal text works reliably.
Is iPhone Safari a good reading surface for serious Japanese immersion?
For short, casual reading (articles in transit, social posts, news headlines) it is workable once you set up the tools above, especially 10ten Reader for in-Safari lookup. For longer sessions where you want fast lookup, instant save, and a real spaced repetition loop in one tool, a laptop or desktop browser with a popup dictionary is still the better surface. Treat mobile as the discovery layer and desktop as the save layer; reviews can happen on either.
