With 125+ million speakers worldwide, Japanese is one of the most widely spoken languages — and Hapi supports it with fully local, private transcription on your Mac.

Three writing systems (hiragana, katakana, kanji), context-dependent word boundaries, and honorific levels make Japanese transcription complex.

How Japanese Speech Recognition Works

Modern speech recognition for Japanese uses transformer-based AI models trained on thousands of hours of Japanese audio. Hapi runs these models directly on your Mac's Apple Silicon chip, so your Japanese audio never leaves your device.

The transcription engine automatically detects Japanese and applies language-specific processing including punctuation, capitalization, and special character handling.

How to Transcribe Japanese Audio on Mac

1. Download Hapi — it's free and installs in under a minute
2. Press the hotkey (customizable) to start recording
3. Speak in Japanese — the language is detected automatically
4. Release the hotkey — your transcription is auto-pasted wherever your cursor is

That's it. No configuration, no cloud accounts, no language selection menus. Hapi detects Japanese automatically and transcribes locally on your Mac.

Japanese Transcription Accuracy Tips

• Speak at a natural pace — the model handles kanji conversion automatically
• Use pauses between separate thoughts for better sentence segmentation
• Mixing Japanese with English loan words works well

For the best results, use a dedicated microphone rather than your Mac's built-in mic, especially in noisy environments.
