Japanese qualified invoice generator
Since October 2023, deducting consumption tax in Japan needs a qualified invoice: registration number, per-rate totals, the tax amount for each rate. This page fills in the mandatory items, validates the T-number check digit, does the per-rate rounding the rules expect, and prints to PDF — all locally.

How it works
- Enter your company details and T registration number — the check digit is verified as you type.
- Add the line items with their tax rate (10% or reduced 8%). Totals per rate are computed for you.
- Print. Your browser’s "Save as PDF" gives you the finished invoice; your data stays on your machine.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
What makes an invoice a “qualified invoice” (適格請求書)?
Six mandatory items: issuer name with registration number, transaction date, description (marking reduced-rate items), totals split by tax rate with the rate shown, the consumption-tax amount per rate, and the recipient’s name. This form includes all of them.
How is the registration number validated?
A corporate registration number is T + the 13-digit corporate number, whose first digit is a check digit — we recompute it locally. Sole proprietors get a number that is not a corporate number, so for those only the format can be checked. No lookup is sent anywhere.
How is the tax rounding handled?
The invoice system allows one rounding operation per tax rate per invoice — not per line. This page follows that: line amounts are added up per rate and the tax is rounded once, with floor, round or ceiling selectable (floor is the common choice).
Is my customer and pricing data uploaded?
No. There is no server call at all: the page works offline once loaded. If you tick “remember my details”, your own issuer block is kept in this browser’s local storage only.
