You will find the Japanese file is marked in different colorful boxes. Check if the OCR applied zone is marked properly. For illustration, if you want to export a part of the Japanese file as Tables instead of Text, mark this part with the Table box by clicking on the icon “Mark Tables”. Once ready, close the interface.

Readiris 17 for Windows, is an intelligent PDF tool to create, convert, OCR, annotate/comment and manage PDF files. Most of users speak highly of its OCR feature, it brings accurate OCR results, supports more than 130 languages. Even when you just have a paper Japanese document in hand, you can directly put the paper file in the scanner, then connect the scanner and your computer to import the Japanese file.
While, as for the “Edit” feature, though it says it is capable of editing PDF, it cannot. As I have tried, it just allows users to convert the native or scans to Word or other editable format, then open the file in the defaulted processor for editing. That’s to say, it doesn’t allow users to edit PDF text within the program directly.
Scan&Translate from AISBERG LLC is a iOS app to recognize image text, then translate to your target language, this is extremely convenient for users who need real-time translate when travelling in Japan. All you need to do is, take a picture of the Japanese information, then scan and translate with this app, even it can read the text for a better communication.
It has an excellent support on OCR language and target translated languages:
Yomiwa, a Japanese OCR app with Dictionary, is really a great tool for users who want to study Japanese anytime and anywhere.
It can recognize text from uploaded images, from files captured under your camera, even handwritten text you input by drawing/radical search/keyboard. Once the OCR finishes, each Japanese word and Kanji will be provided with detailed information, such as pronunciation, conjugation or definition. Also, the Japanese contents can be translated into more than 10 languages.
However, Yomiwa can only translate single Japanese word or Kanji, it is not capable of translating a complete sentence. To translate the whole file, you will need to copy the text, then paste to a 3rd party translator.
