Three Strata of Words
Modern Japanese draws on three main sources:
- Yamato kotoba / wago (和語) – the original native layer
- Kango (漢語) – words of Chinese origin or modeled on Chinese
- Gairaigo (外来語) – later foreign loans, especially from European languages
A major dictionary estimates the split as roughly 49% kango, 34% wago, 9% gairaigo, with another 8% hybrid forms.
Native vs. Sino-Japanese: Echoes of Latin in English
Just as English pairs plain Anglo-Saxon words with fancier Latin ones ("ask" vs. "inquire"), Japanese often has:
- A Yamato term that feels everyday and concrete
- A Sino-Japanese counterpart that sounds more formal or technical
Kango entered from the 5th century onward alongside Chinese culture, reshaping not only vocabulary but phonology.
European Waves: From Pan to Pasokon
The first Western loans came from Portuguese in the 16th century:
- pan – bread
- tabako – tobacco, now "cigarette"
During Japan’s isolation, Dutch provided specialized terms. After the Meiji Restoration, borrowings widened to German, French, and especially English.
Modern Japanese bristles with English-based gairaigo, particularly in technology:
- pasokon – personal computer
- intānetto – internet
- kamera – camera
So many English loans arrived that Japanese even developed new sound distinctions, like [ti] vs [tɕi], just to accommodate them (paati for "party", dizunii for "Disney").
Words Japan Exported Back to Asia
In the Meiji era, Japanese thinkers coined wasei-kango—"Japanese-made Chinese words"—to translate Western concepts using Chinese roots. These neologisms, such as:
- seiji (政治) – politics
- kagaku (化学) – chemistry
were later adopted into Chinese, Korean, and Vietnamese. The result is a shared technical vocabulary across East Asia, comparable to Greek- and Latin-based terminology in Europe.
Made-in-Japan English: Wasei‑Eigo
Japanese also coin playful hybrids from English parts, known as wasei-eigo ("made-in-Japan English"):
- wanpatān (one + pattern) – being stuck in a rut
- sukinshippu (skin + -ship) – physical closeness or affectionate touch
To native English ears they sound odd, but in Japan—and sometimes in neighboring Korea—they function as perfectly normal words.
The Takeaway
Every Japanese sentence is a palimpsest: traces of ancient Yamato speech, centuries of Chinese scholarship, and waves of European influence layered on top. Far from diluting the language, these borrowed and built words have made Japanese a nexus in the flow of ideas across Asia and the modern world.
