Where this applies
Read on the Digital Agency's own statute portal, in the version in force from 1 April 2026; the Act itself dates from 1952, which is the most useful thing about it — this requirement was not written with any technology in mind and simply happens to bind one now. Article 35(1) requires the broker to have a 宅地建物取引士, a licensed transaction specialist, deliver a written document and explain at least the listed matters before the contract concludes; the list runs to registered rights over the land, planning and building-code restrictions, private-road burdens, the state of water, electricity, gas and drainage, and for an existing building whether a condition survey has been carried out and what it found. Paragraph 4 requires that specialist to present their licence card when giving the explanation, and paragraph 5 requires them to put their name on the document. Two qualifications keep this from being read as more than it is. The document may be provided by electronic means with the counterparty's consent, which replaces the signature and seal — so the duty is a licensed person, not paper and not physical presence. And paragraph 6 disapplies paragraphs 4 and 5 and relaxes the wording where the counterparty is itself a licensed broker: the personal explanation is owed to a consumer, not between professionals. It binds transactions in Japan. It counts nobody and says nothing about how these explanations are prepared.
What this means
In Japan the person who explains what you are buying has to be licensed, has to show you their licence while doing it, and has to put their name on the document. The explanation itself is the regulated act, not the paperwork behind it — and the duty attaches to a named individual rather than to the firm. A law written in 1952 turns out to be the hardest constraint on this page, for a reason that has nothing to do with technology: somebody has to be answerable for what was said.
What it does not yet show
This constrains who does the explaining, not how the explanation is produced. Nothing stops a firm from generating the entire document and every disclosure with software; the law only requires a licensed person to deliver it and be named on it. Two carve-outs matter: the document may be provided electronically once the counterparty consents, so this is not a requirement to be in the room, and the personal-explanation duty is disapplied where the counterparty is another licensed broker. It applies in Japan and counts nobody.
What you can check
Wherever you work, find out whether your name goes on anything. Ask which document in your transaction carries an individual's name rather than the company's, and what happens to that individual if it turns out to be wrong. Where the answer is nothing and nobody, the explaining part of your job is the part with no one standing behind it — and that is the part that moves first.
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
