Check your product pages against each market’s labeling rules before you sell.
Hyoji shows what is missing, how to fix it, and the official source for each rule. When a rule changes, it re-checks only the affected products and tells you.

Why it is not a one-time fix
Labeling rules change.When they do, we re-check
Labeling rules change with new laws (for example, the US law passed in 2022, MoCRA, added items that cosmetics labels must show). When a rule in our ledger changes, Hyoji publishes a new version and then:
- 1Re-checks only the products affected by the change
- 2Shows products that need new fixes on the app home
- 3Keeps the records made under the previous version

FAQ
If everything “meets”, can I sell in that market?
No. The checks are for reference and look only at product page text. Rules are drafted with AI from official sources, and some have not been reviewed by an expert (we show this per rule). The store is responsible for the final judgment on compliance.
Can I cancel after fixing everything?
You can cancel a paid plan anytime, and your records stay. If you uninstall the app, records are deleted within 48 hours, so export them first if you need them (export is on Growth and above).
Will Hyoji change my products?
No. Hyoji asks only for permission to read products. It does not read customer data.
Does it work if descriptions are only in Japanese?
It runs, but most markets require labeling in the local language, so you will see many “missing” results. Prepare descriptions in the market’s language first.
Can I use it on my phone only?
Yes. Open it from the Shopify mobile app to run checks and review results.
