In Japanese, writing “Congo” as “公果” comes from the tradition of ateji (phonetic substitutions using kanji) and the influence of Chinese notations. This form was chosen for its sound rather than its meaning and appears mainly in historical documents and translated materials.

Background of the notation “公果”

“公果” corresponds to the katakana “コンゴ” (Kongo) through the use of kanji as phonetic substitutes. Japanese has long had a tradition of assigning kanji to foreign place names and personal names, and this notation appeared in translations that referenced Chinese-language materials. It was especially common in newspapers, maps, and diplomatic documents from the Meiji to the early Showa period. At that time, kanji were favored as official and visually refined characters, giving a more dignified impression than katakana. Another factor was that the Chinese notation for Congo was similar to “公果,” which likely influenced its adoption in Japanese.


Meaning and phonetics of the kanji

The two characters in “公果” have the following meanings and readings:

KanjiOn-yomi (Chinese-derived reading)Main Meaning
kō, kupublic, fair, shared by many
ka, kufruit, result, to accomplish

The on-yomi “kō” approximates “kon,” and “ka” approximates “go,” so the combination recreates the pronunciation “Kongo.” Ateji often prioritize sound over meaning, and a direct translation of the characters can result in nonsensical phrases. For example, a literal reading of “公果” might suggest “public fruit,” which has nothing to do with the actual country. This is why it’s important to clarify that it’s a purely phonetic notation.


Ateji culture and the notation of foreign place names

The Japanese ateji culture developed as a unique way to represent foreign words using kanji. In place names especially, visual harmony and readability often determined the choice of characters.

公果KongoRepublic of the Congo / Democratic Republic of the Congo

While these notations were once widely used, modern Japanese largely favors katakana for foreign words, and ateji now appears mostly in historical documents or decorative contexts.


Congo in Chinese and its influence on Japanese

In Chinese, Congo can be written as “刚果” or “剛果”, which, like “公果,” are phonetic transcriptions in kanji. From the Meiji period onward, Japanese translators often relied on Chinese materials to assign kanji to foreign place names. This practice likely led to the adoption of “公果” in Japanese. The table below shows similar examples between Chinese and Japanese notations.

This demonstrates how place name notations within the Chinese-character cultural sphere have influenced each other over time.


Modern usage

Today, “コンゴ” in katakana is the sole official form in Japan, appearing in diplomatic documents and news reports. However, in reading historical texts or old maps, one may still encounter the kanji “公果.” For foreign learners of Japanese, this is valuable knowledge for understanding Japanese language history and kanji culture. Understanding the translation history within the Chinese-character sphere offers insights into the origins of words and the history of cultural exchange.


Conclusion

“公果” is a historical Japanese notation that prioritizes sound over meaning by using kanji as phonetic symbols. It emerged from a blend of Chinese notation, contemporary printing culture, and interactions within the Chinese-character cultural sphere. While it is rarely used today, it remains an important example for understanding the variety of writing systems in Japanese.
