Your school address is the proof.
Every other student discount site asks you to upload a photo of your student card and wait for someone to squint at it. This one asks for the address your institution already gave you, sends it a code, and forgets the address the moment it has served its purpose.

What happens when you verify
You type your school address
The domain tells us which institution issued it. That is the part we keep — not the address in front of it.
We send six digits to it
Receiving the code is the proof. Nobody reads a document, and there is no queue for a human to approve you.
You type the code back
It expires in ten minutes, works once, and gives up after three wrong guesses.
The address is discarded
What persists is your institution and an irreversible hash — enough to recognise you next time, useless to anyone reading our database.
What we are told, and what we keep
What we keep
- Which institution issued your address
- An irreversible hash of the address, which means nothing outside this site
- When you verified, and when that runs out
What we never keep
- Your email address, which is used to send the code and then dropped
- Your name
- Your student number
- Your course, year, or anything else on your record
Be clear about the one difference from a federated login: you do type your address here, so it passes through this service on its way to your inbox. It is never written to the database. The consequence is deliberate and worth knowing — because we hold no address, we can never email you again, about anything.
Is your school covered?
Recognising a school means knowing which domains it issues. Most Japanese universities sit under ac.jp, but several of the largest private ones use their own domain instead, so this is a list rather than a pattern — and a list starts incomplete.
24 institutions are recognised today.
- Aoyama Gakuin University
- Chuo University
- Doshisha University
- Hiroshima University
- Hokkaido University
- Hosei University
- Institute of Science Tokyo
- Institute of Science Tokyo

The awkward questions
- Does this mean you have an account for me?
- Only a record that some institution issued an address to someone, and a hash to recognise that same person again. There is no name on it and no address, so there is nothing to look you up by.
- How long does it last?
- Six months. Shorter than a federated login would be, for an honest reason: school addresses often keep working after graduation, so the proof decays faster than a university's own answer would.
- Why not use my university login instead?
- We would prefer to. Federated verification proves you are enrolled today rather than that an address was once issued to you. Admission to Japan's federation is by committee and covers a fraction of institutions, so building on it alone would mean most students waiting indefinitely. When it is available it will sit alongside this, not replace it.
- What if my school never gave me an address?
- Then this route cannot reach you yet, and we would rather say so than pretend otherwise. It is the honest weak point of verifying by email, and widening coverage is the work.
- Why not just accept a photo of my student card?
- Because a photo proves nothing. They are forged constantly, checking them means a human reading your name and face, and the merchants who fund these offers know the difference.
