Q. Is there a relationship between the number of bones and wind?

A. Folding fans generate wind through the flexibility of the bamboo, so the more ribs a fan has, the softer the breeze you can enjoy.


In folding fans, each rib is counted as "1 ken," and at Isetan Shinjuku Store, Men's Building we offer fans with approximately 60 to 70 ken, allowing you to feel a gentle breeze. On the other hand, fans with fewer ribs, around 20 ken, create a larger surface area and allow you to feel a stronger breeze.

The strength and softness of the breeze vary depending on the brand and design, so try them out in stores to find your favorite.


Q. What is the correct way to open and close a folding fan?

A. Support the fan with your left hand and gently hold the main ribs with your right hand. Keeping your left hand still, slowly open the fan using only your right hand.

When closing the fan, just as when opening it, support it with your left hand and use your right hand to carefully and slowly close each rib one by one.
Also, the common practice of opening a fan forcefully with a "bang" puts stress on the key parts, causing the fan surface to retain its shape and potentially breaking .
