Furigana, Native Audio, and Hover-to-Translate Sentences in Cotobara

Most people don't quit Japanese because the vocabulary is hard. They quit because of friction: an example sentence with three kanji they can't read, a word they've never heard pronounced, a phone with no Japanese keyboard. Each one is small. Together they turn a five-minute study session into a chore.

Cotobara's reading tools exist to delete that friction. Here's what they are.

Furigana — on when you need it, off when you don't

Every Japanese word and sentence in Cotobara can display furigana: the kana reading printed above the kanji, rendered with the browser's native ruby text so it sits properly rather than crowding the line.

It's a single toggle in Settings, and the right answer changes as you improve:

There's no single right setting, which is why it's a toggle and not a policy. Many learners flip it off, struggle for a week, and leave it off.

Native audio on everything

Every vocabulary word, every example sentence, and every kana character in the beginner course is pre-recorded with high-quality neural voices, in both male and female sets.

That matters more than it sounds. Japanese is full of pitch-accent distinctions and long/short vowel contrasts that written romaji simply doesn't capture — 箸 (chopsticks) and 橋 (bridge) are the same syllables with a different melody. If you only ever read a word, you learn a version of it that native speakers won't recognize, and that's much harder to unlearn later than to learn correctly the first time.

Audio plays automatically when you want it to (there's an autoplay toggle) and on demand from a speaker button everywhere a word appears. One deliberate exception: the lesson quiz never autoplays. A question that pronounces its own answer isn't a test.

Hover-to-translate example sentences

This is the feature people mention most.

Every word comes with a real example sentence, because a word in isolation only half-teaches you — you need to see what it attaches to, which particle it takes, and what register it belongs to.

The problem with example sentences at a beginner level is that they contain other words you don't know yet. Traditionally you'd stop, open a dictionary, look up three words, and lose your place.

In Cotobara, point at any word in a sentence and you get its reading and its meaning, right there. No new tab, no dictionary app, no losing your place. The sentence is broken into real words rather than characters, so you're hovering 食べます, not 食.

Two touches that make it usable rather than annoying:

The result: you can read an example sentence at any level without leaving the page.

Type kana without an IME

On reading questions you type the answer in kana — and you type it in romaji, which converts as you go. ta becomes た as you finish the syllable, kya becomes きゃ.

No Japanese input method, no OS settings, no keyboard switching. This works on a laptop you don't control and on a phone without touching your keyboard settings. Setting up a Japanese IME is a genuine barrier for beginners, and it's a strange one to put between someone and their first study session.

A couple of details that keep it from being frustrating: hiragana and katakana answers are treated as equivalent, so you're never marked wrong for the script you chose. And if you leave stray romaji that never converted, the field nudges you to fix it instead of quietly marking you wrong.

It all shows up on the public word pages too

You don't need an account to see most of this. Every word in Cotobara has a public page with its reading, furigana, meaning, part of speech, pitch accent, example sentences with hover glosses, and audio. Look up a word from a search engine and you get the real thing, not a signup wall.
