Japanese Loanwords in Korean
Toshi, Kuruma, Sara — Japanese traces Koreans don't even realize
Hundreds of Japanese loanwords from the colonial period (1910-1945) remain in Korean. Most Koreans use them without realizing they're Japanese. While standardized alternatives exist for many, Japanese-origin terms persist strongly in construction sites, slang, and adult vocabulary.

Why So Many Remain
- 35 years of colonial rule: Japanese was used across education, administration, military, and industry
- Post-liberation generational transfer: The generation that spoke Japanese natively passed it to children
- Construction apprenticeship culture: Technical terms passed orally from seniors to juniors
- Slang excluded from purification efforts: Official language reform focused on formal vocabulary
- Semantic drift: Many words shifted meaning, becoming uniquely Korean — obscuring their Japanese origin
Key Points
Daily: toshi, tama, kuruma, sara, oden, udon, etc.
Construction: demodo, kata, shiage, hamba, pparu
Adult slang: sakkashi, ppaguri, skinship (wasei-eigo)
35 years colonial rule + generational transfer + apprenticeship = hard to purify
Many words shifted meaning, obscuring Japanese origin awareness
