Karakuri gasa concretely meant a Japanese-style umbrella (oddly, also described as a Chinese-style umbrella), and the name karakuri gasa was given because a mere canopy of Chinese origin was changed into the convenient tool equipped with the device for opening and closing in Japan.
-和傘のことで、唐傘とも表記するが、中国由来のただの天蓋であった傘を、日本で開閉式の仕掛けを施した事で、唐繰傘と呼ばれた。
