OCR for Japanese text

[Alexander Zapryagaev (萌覺・Miǒgacu)]

Hello everyone!

I wonder: what is the best tool to OCR Japanese text? I tried many throughout the years and am yet to find one that handles text in vertical column without problems. And even if it does a half-decent job, any appearance of furigana completely stumps any product I tried. What OCR solutions are used in Japan? Could someone recommend me a tool (preferrably open-source) that can confidently handle Japanese, both horizontal and vertical (and other East Asian languages as a bonus, if possible)?

Best wishes,

Alexander Zapryagaev

Surely someone here will have a better answer, but the best tool I've found so far is OnlineOCR (via browser on https://www.onlineocr.net/). I am testing Gemini Pro to extract text from images and it might be better, but I haven't used it extensively enough yet, as I have done with OnlineOCR. Having said that, though, OnlineOCR still presents some mistakes, sometimes misrepresenting a kanji or breaking it into multiple kanji and that sort of thing, so you'll always have to proofread it, just in case.

Kind regards,

Kauê Otávio

Hello everyone,

I noticed the previous threads are from a little while back and don't
mention the NDLkotenOCR software, which is free, open source, and
available for Windows, Mac and Linux. It's also much higher quality
than any other Japanese OCR software I've ever tried.
