Yomasete OCR — Paper forms in, the same tidy fields out.
- Web
- API
Yomasete OCR reads Japanese business forms such as invoices, delivery notes, quotes and receipts, and turns them into data your systems can use. Set up a form once, and every copy of it comes out with the same fields.

Why
Why we build it
Many offices still type in invoices and delivery notes that arrive on paper or by fax, one sheet at a time. Plain OCR only returns lines of text, while a business system needs the right value in the right field.
Features
What it does
One template per form
A template is a reference image with named zones, so every document of that form becomes JSON with the same keys.
Handwriting models
Dedicated models read handwritten digits, amounts and phone numbers, and English letters.
Tables and receipts
It reads tables with or without ruled lines row by row, and splits a page holding several receipts into separate ones.
Rule fixes and master lists
Rules clean up Japanese-era dates, full-width digits and yen amounts, and values are matched against master lists you upload as CSV.
How it works
How it works
Upload one sample page and AI drafts a template; adjust the zones and save it.
Upload scans, PDFs or phone photos of the same form as a batch.
Each page is straightened, matched to the template and read zone by zone.
Check the flagged values, approve, and export JSON, CSV or a searchable PDF.
Roadmap
Now and next
Now
In developmentIn development and running as a test deployment, with a web app and an API. We are also building a tablet demo app where invoices are written by hand and read by the same models.
Next
- Finish workflows that link reading, checks and sending results to other systems
- Let each organisation train text models on its own documents, not only digit models
- Test the handwriting demo app on real tablets with a pen
