Kyūjitai


Kyūjitai are the traditional forms of kanji. Their simplified counterparts are shinjitai. Some of the simplified characters arose centuries ago and were in everyday use in both China and Japan, but they were considered inelegant, even uncouth. After World War II, simplified character forms were made official separately in Japan and mainland China, with Japan adopting fewer and less drastic changes. For example, 電 remains unchanged, whereas it was simplified to 电 on the mainland.
Prior to the promulgation of the tōyō kanji list in 1946, kyūjitai were known as seiji or seijitai. Even after kyūjitai were officially marked for discontinuation with the promulgation of the tōyō kanji list, they were used in print frequently into the 1950s due to logistical delays in changing over typesetting equipment. Kyūjitai continue in use to the present day because when the Japanese government adopted the simplified forms, it did not ban the traditional forms. Thus, traditional forms are used when an author wishes to use them and the publisher agrees.
Unlike in the People's Republic of China, where all personal names were simplified as part of the character simplification reform carried out in the 1950s, the Japanese reform applied only to a subset of the characters in use and excluded characters used in proper names. Therefore, kyūjitai are still used in personal names in Japan today. In modern Japanese, kyūjitai that appear in the official spelling of proper names are sometimes replaced with the modern shinjitai form.

These characters are Unicode CJK Unified Ideographs for which the old form and the new form have been unified under the Unicode standard. Although the old and new forms are distinguished under the JIS X 0213 standard, the old forms map to Unicode CJK Compatibility Ideographs which are considered by Unicode to be canonically equivalent to the new forms and may not be distinguished by user agents. Therefore, depending on the user environment, it may not be possible to see the distinction between old and new forms of the characters. In particular, all Unicode normalization methods merge the old characters with the new ones.
