Description

The Japanese government conducted the Moji Jōhō Kiban Project (文字情報基盤整備事業), which aimed to collect and consolidate, from a glyphic perspective, all ideographic characters used for government administrative purposes. This project was conducted by the Moji Jōhō Kiban Committee under the IT Strategic Headquarters, an organization within the Japanese Cabinet Office.

All of the glyphs have been mapped to corresponding code points in ISO/IEC 10646 and the Unicode Standard, and glyphs that were unified under a single code point but needed to be distinguished for administrative purposes were registered in this IVD collection. The glyphs proposed through this project are assigned J-source references with a “JMJ-“ source prefix in ISO/IEC 10646 and the Unicode Standard, and with a corresponding “MJ” prefix in the registered Moji_Joho IVD collection.

The Moji Jōhō Kiban Project inherited the Hanyo Denshi Program (汎用電子情報交換環境整備プログラム), and as a result, the Moji_Joho IVD collection shares 9,866 of the IVSes registered in the Hanyo-Denshi IVD collection.

In 2020, all of the deliverables associated with the Moji Jōhō Kiban Project (文字情報基盤整備事業) were transferred to CITPC (Character Information Technology Promotion Council 文字情報技術促進協議会).
