Article 2 defines a sword by measurement: a blade of fifteen centimetres or more for a sword, spear or naginata, five and a half for a dagger. Article 14 then carves out an exception. The prefectural board of education registers old firearms of value as art or antiques, and swords of value as art, on the basis of an appraisal by registration examiners appointed for their scholarly knowledge.
The cool part. A Japanese sword is lawful to own because it has been certified as art. Not because it was disarmed, not because it was licensed as a weapon. The judgement is made by the board of education, and Article 14 then requires the board to notify the prefectural public safety commission of what it has decided. The culture side rules, and the police are informed afterwards. Fail the appraisal and the same object becomes contraband.
