DefinitionJIS (Japanese Industrial Standards, 日本産業規格) are the national standards Japan sets for domestic industrial products, data, services and more.
ExplanationUnder the Industrial Standardization Act, JIS are, as a rule, enacted by the competent minister after review by the Japanese Industrial Standards Committee (JISC). A revision of the law that took effect in July 2019 added data and services to the scope and changed the Japanese name from 日本工業規格 ("industrial") to 日本産業規格 ("industry"). JIS based on international standards often use matching numbers, and in the management system field they carry the symbol "JIS Q".
AnalogyThink of it as Japan's official rulebook, with many chapters written to match the worldwide rulebook.
Memory hookJ is Japanese and S is Standards. The I is Industrial from the old name, and even after the renaming the English name is still Japanese Industrial Standards.
