Through the investigation of Asahi Shimbun, Katakana sofuto was introduced as a soft hat which expresses a soft “trilby hat” against a “mountain cap” in the study. Gradually, sofuto began to appear in Japanese as a modifier and its meaning expanded. Soon, the adjective verb sofutona appeared. Since then, loanwords and their new modification methods have been absorbed by Japanese and occupied part of the meaning of yawarakana, but they have little influence on junan'na.
