JIS X 0510:2018 is the Japanese Industrial Standard for the QR Code, maintained by the Japanese Industrial Standards Committee (JISC). The QR Code was invented in Japan by DENSO WAVE in 1994, and the original JIS standard — first published in 1999 — predates the international ISO version and served as its foundation. The 2018 revision aligns the Japanese standard with ISO/IEC 18004:2015, keeping the national specification consistent with the global one. As the standard of the QR Code's country of origin, JIS X 0510 holds particular historical significance in the symbology's development, defining the same core structure, encoding, and error-correction principles that became the worldwide norm. It remains the authoritative Japanese reference for QR Code generation and reading.
