Describe what the seal is for - opening a bank account, signing a real estate contract, or marking a piece of art - and Claude AI matches you to the real Japanese personal seal (hanko/inkan) type that fits, explaining registration rules and the etiquette real users follow.
Description
In Japan, a hanko (also called inkan) - a carved personal seal stamped in red ink - still stands in for a signature on everything from apartment leases to corporate contracts. But outside Japan, almost no one knows there isn't just one kind of hanko: different seals carry different legal weight, and using the wrong one for the wrong purpose is a real, everyday mix-up. Describe what you need the seal for in a sentence - opening a bank account, buying a car, signing an apartment lease, registering as a company representative - and our AI, playing the role of a hanko specialist, matches you to the real seal type that purpose calls for, from three genuine categories: jitsuin (the registered seal used for major legal contracts), ginkoin (the bank seal used for financial accounts), and mitomein (the everyday seal used for informal acknowledgments and deliveries). Each match comes with a clear explanation of why that seal type fits the purpose, the real registration process it requires where relevant (such as jitsuin registration at a local ward office), and a genuine etiquette note - how a seal is properly stamped and stored, and why certain script styles are chosen over plain print lettering for security. The Seal Types tab lets you browse all three categories as a standalone reference any time, even without asking for a match. Your past matches are saved to a personal history so you can revisit them next time a new situation comes up. A limited number of free matches are available each day, with the option to unlock more by watching a short ad.

Why This App

Most explanations of hanko treat it as one generic "name stamp," missing that jitsuin, ginkoin, and mitomein carry real, different legal weight and etiquette. Hanko Seal starts from an everyday purpose and matches it to the correct seal category with real registration guidance - turning a confusing cultural detail into a small, practical piece of knowledge.
