扇子
せんす
sensu
= folding fan; a Japanese folding fan
扇子 (sensu) is the Japanese folding fan — one of Japan’s most elegant inventions, exported to China and the world from around the 9th century. Far more than a cooling device, the sensu is a prop in traditional arts, a formal accessory, a gift item, and a cultural symbol. The snap of a sensu opening is one of the defining sounds of Japanese traditional performance.
Sensu (扇子) is a folding fan with a bamboo or wooden frame and paper or silk covering. Types: 白扇 (hakusen — white folding fan for formal use), 舞扇 (maiougi — dance fan, larger and more decorated), 茶扇子 (cha-sensu — tea ceremony fan, very small, used as a formal prop rather than for actual fanning). Different from: うちわ (uchiwa — a rigid round fan, used for casual fanning). Usage: 扇子を広げる (sensu wo hirogeru — to open a fan), 扇子を扇ぐ (sensu wo aogu — to fan with a fan).
In traditional Japanese arts, the sensu is a versatile prop: in Noh theater it represents many objects (sword, cup, boat); in rakugo comedy storytelling a single sensu and hand towel represent every object in the story; in traditional dance (日本舞踊, Nihon buyo) it’s essential equipment. Etiquette: a sensu is often placed in front of you on tatami as a礼 (rei — respectful gesture) when greeting in formal settings — the fan creates a boundary between you and the other person, representing respectful deference. Never point at someone with an open fan.
扇子 combines 扇 (ougi/sen — fan) + 子 (ko/shi — small object, child). 扇 combines 户 (to — door) + 羽 (hane — feathers, wings). The image: wings in a door = something that opens and closes like a door while fanning like feathers. The sub-character 户 (door) gives sensu its opening-and-closing character. 扇 alone (read ougi) means fan; 扇子 (sensu) is the compound.

Formal / Cultural context
扇子（折り畳み扇）は日本が発明した携帯型送風具であり、ヒノキの薄板を束ねた桧扇（ひおうぎ）として平安時代（794年〜）に成立し、10世紀前後に中国・朝鮮半島を経てアラビア・ヨーロッパへと伝播したとされる。17世紀にポルトガル・スペインを通じて欧州宮廷に普及した折り畳み扇はヨーロッパの貴族文化に深く浸透し、「扇言語」（扇の持ち方・角度による意思疎通）と呼ばれる独自の通信様式も発展した。

The sensu (folding fan) is a portable cooling device invented in Japan, established in the Heian period (from 794 CE) as the hi-ougi (a bundle of thin cypress boards), and said to have spread around the 10th century through China and the Korean Peninsula to Arabia and Europe. The folding fan that spread to European courts through Portugal and Spain in the 17th century deeply penetrated European aristocratic culture, and a unique communication style called ‘fan language’ (communication through how the fan was held and its angle) also developed.
京扇子 (Kyoougi — Kyoto folding fans) are considered the pinnacle of Japanese fan craft, with production centered in Kyoto since the Heian period. Kyoto fan making is a highly divided process — traditional Kyoto sensu involve 88 distinct production steps performed by different specialist craftspeople, from the frame maker (骨師, honeshi) to the paper cutter (切り師, kirishi) to the final paper-layer applier (貼り師, harishi). This extreme division of labor reflects the guild system that developed around luxury crafts in Kyoto over centuries.
扇子 in Japanese traditional arts function as universal props that represent virtually any object through convention and imagination. In 落語 (rakugo — traditional comic storytelling), a performer sits alone on stage with only a sensu and a 手拭い (tenugui — hand towel). The sensu becomes a chopstick, a brush, a pipe, a sword, a fish. The audience’s imagination does the rest — a convention that makes the performer’s skill at ‘using’ the prop the central theatrical achievement. This minimalist symbolic use of the fan distinguishes Japanese theatrical tradition from Western theatrical realism.
