Holding the prescribing pen
Signing for a prescription, a referral, a sick note or a test — the acts where the doctor's name is what makes the thing valid.

Where this applies
Read on the Digital Agency's own statute portal, in the version in force from 21 May 2026; the Act dates from 1948. Article 20 states that a physician shall not provide treatment, or issue a medical certificate or a prescription, without personally examining the patient; shall not issue a birth or stillbirth certificate without personally attending; and shall not issue a postmortem certificate without personally conducting the examination. One exception is written in: a death certificate for a patient under treatment who dies within twenty-four hours of the consultation. Article 33-3 makes a breach of Article 20 punishable by a fine of up to ¥500,000, so this is a criminal prohibition on the physician personally, not a professional guideline. State plainly what this record does not cover: the Act does not define what personally examining requires, and how it applies to remote or video consultation is set by Ministry of Health, Labour and Welfare guidance that was not read for this record — so nothing here should be taken to mean the physician must be in the room. What it does establish is narrower and harder: the prescription is attached to an act by a named licensed person, and the law does not contemplate that act being performed by anything else. It binds practice in Japan and counts nobody.
What this means
The prescription is attached to a person, by criminal law, and has been since 1948. A physician who treats or prescribes without having personally examined the patient commits an offence, not a breach of professional etiquette. Whatever produces the suggestion, the act of prescribing is one the statute assigns to a named licensed individual and does not contemplate being performed by anything else.
What it does not yet show
This protects who signs, not how the judgement is reached. Nothing in it restricts software from producing the differential, the dose or the draft; the physician may rely on all of it and still satisfy the Act by examining and prescribing themselves. It also does not say the physician must be present in person — the Act leaves personally examining undefined and the ministry guidance on remote consultation was not read for this record. And it counts nobody: no visits, no prescriptions, no change in anyone's hours.
What you can check
Look at who the law makes answerable in your own country for a prescription, and then look at how much of the reasoning behind one is now produced before the consultation starts. The gap between those two is where this occupation actually changes — not at the moment a tool gets good, but at the moment the answerable person stops being the one who worked it out.
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 rests on evidence instead of inference.
