Japanese umbrellas originated from the canopy-type silk umbrellas which came from China and the sedge umbrellas used by nobles during the Heian period.
Japanese umbrellas increased along with the number of people living in cities in the Edo period and the development of paper and bamboo designs.
During the early and mid Edo period, "bull's-eye" design (janome) umbrellas and coarse oil-paper umbrellas began to be produced.
The opening and closing spring was added and it is said that long umbrellas were banned and so came to be the length they are today.
In the Showa period (1926-1988) western umbrellas became more common and from 1955 onwards robust umbrellas with colorful designs made from cheap nylon and Tetron appeared and demand for Japanese umbrellas has dropped drastically. Kanazawa paper umbrellas are designed to withstand the harsh local winter conditions.
Some features of these umbrellas are four layers of paper in the center and two to three threads wound around the outside to strengthen the
easily breakable parts. These umbrellas thus have a stronger frame,
with thicker ribs compared to other Japanese umbrellas and are robust and long@lasting.
