How to properly handle a Japanese folding fan (Sensu)

Before diving into the mechanics of handling a sensu, it is essential to understand its structural components. A traditional sensu consists of the 'oyahone' (the two thicker outer ribs), the 'nakahone' (the thinner inner ribs), and the 'jigami' (the paper or silk pleated surface). The pivot point at the base that holds everything together is called the 'kaname'—a word that is also used in Japanese to describe the most important part of any matter. Understanding this anatomy is crucial because each part requires specific care. For instance, the jigami is often delicate and can be easily damaged by moisture or rough handling. Knowing that the ribs provide the structural integrity allows you to apply pressure in the right places when opening and closing the fan without risking a snap or a tear.

The act of opening a sensu is often the first place where beginners falter. It should never be flicked open with a sharp snap of the wrist. While this might look dramatic in movies, in real-life Japanese etiquette, it is considered aggressive and potentially damaging to the fan. To open a sensu properly, hold the fan in your right hand with the thumb on the front oyahone. Use your left hand to gently slide the ribs apart, unfolding them one by one or in a smooth, controlled motion. In formal settings, it is actually considered polite to leave the last one or two pleats of the fan closed. This 'incomplete' opening symbolizes modesty and the idea that there is always room for growth or more to learn, a concept deeply rooted in Japanese philosophy.

When it comes to the actual cooling action, subtlety is key. In Western cultures, people often fan themselves with large, vigorous strokes that create a lot of noise and wind for those nearby. In Japan, fanning should be a private affair. Hold the fan slightly below your face, usually around the chest area, and create a gentle breeze with small, rhythmic movements of the wrist. The goal is to cool yourself without disturbing the air around others. It is also important to avoid fanning your face directly from a close distance, especially in the presence of superiors or in a quiet environment. The motion should be downward or slightly angled toward your neck and chest, keeping your elbow close to your body to maintain a compact and respectful silhouette.

Closing the sensu requires as much care as opening it. Many people make the mistake of trying to force the pleats together all at once, which can result in the jigami getting pinched or folded incorrectly. To close the fan correctly, use the thumb of your dominant hand to guide the ribs back into their stacked position while your other hand supports the base. Ensure that each pleat of the paper or silk sits correctly between the ribs. Once closed, many high-quality sensu come with a small band or a sleeve (kuro-fukuro). Always return the fan to its protective sleeve when not in use. This not only preserves the artwork and the material but also signifies that you value the object, reflecting a core Japanese value of 'mottainai' (gratitude toward objects).

There are several 'don'ts' when it comes to sensu etiquette that every traveler should keep in mind. First, never use a sensu to point at something or someone; this is considered extremely rude. Second, avoid placing your fan directly on the floor or a dirty surface; if you must set it down during a meal or ceremony, place it on top of your own lap or a clean cloth. Additionally, be mindful of the design on your fan. Some patterns are seasonal—for example, maple leaves are for autumn, and plum blossoms are for early spring. Using a fan with a winter motif in the height of summer can be seen as a lack of seasonal awareness (kyokan), which is highly valued in Japanese aesthetics. Finally, never touch the paper part of someone else's fan, as the oils from your hands can stain the delicate jigami.

In formal situations, such as a traditional wedding or a tea ceremony, the sensu serves a symbolic purpose rather than a functional one. In these contexts, the fan is often kept closed and placed in front of one's knees when seated on tatami mats. It acts as a physical boundary, representing a respectful distance between yourself and your interlocutor or the host. This 'barrier' isn't meant to be unfriendly; rather, it defines a space of mutual respect. If you are gifted a fan in such a setting, it is customary to receive it with both hands and a slight bow. Understanding these silent signals can significantly enhance your social interactions in Japan, showing that you have taken the time to learn the deeper layers of the culture beyond the surface-level tourism.

Choosing the right sensu is also part of the etiquette. For men, fans are generally larger (around 22-23cm) and feature more subdued colors or traditional patterns like dragonfly or geometric 'seigaiha' waves. Women’s fans are typically smaller (around 19-21cm) and often feature brighter colors, floral patterns, or more intricate lacquered ribs. When shopping for a souvenir, look for 'Kyo-sensu' from Kyoto, which are handmade and held to the highest standards of quality. By selecting a fan that matches the formality of your attire—for example, a simple bamboo and paper fan for a yukata at a summer festival versus a more ornate silk fan for a formal kimono—you demonstrate an intuitive grasp of 'TPO' (Time, Place, and Occasion), a concept the Japanese apply to almost every aspect of public behavior.
