ソファ
ソファ
sofa
= sofa; couch
ソファ is the Japanese adaptation of the English word “sofa,” referring to the upholstered seating that became a staple of Western-style Japanese living rooms as homes shifted away from traditional floor-based arrangements.
ソファ (sofa) denotes an upholstered multi-seat couch, borrowed directly from English. It appears both as sofa and the extended form sofā (ソファー), with both spellings equally accepted in everyday writing. In casual speech, sofā with the long vowel mark is slightly more common, while ソファ without it appears frequently in product listings and interior design contexts. The word refers specifically to Western-style furniture, distinguishing it from nagaisu (長椅子), a traditional Japanese bench-style seat, and from kauchi (カウチ), which more closely mirrors the English “couch” and often implies a reclining or lounge style. A matched furniture set is called a sofa setto (ソファセット).
The alternate spelling ソファー (with the long vowel ー) is just as correct as ソファ — do not mark one as wrong. A common learner mistake is confusing ソファ with カウチ; in Japanese retail contexts ソファ is the default term for a standard living-room couch, while カウチ typically implies a chaise-lounge style. Also avoid confusing ソファ with 椅子 (isu), which is a general chair.

The spread of ソファ in Japanese homes reflects a broader architectural shift that accelerated after World War II, as yōshitsu (洋室, Western-style rooms) with raised floors and wood or carpeted surfaces became common alongside traditional washitsu (和室, Japanese rooms) with tatami mats and zabuton cushions. In a washitsu, placing a heavy sofa on tatami would damage the delicate rush-grass surface, so the furniture naturally migrated to the yōshitsu portion of the home — a division still visible in many contemporary Japanese apartments.
Interior design media in Japan frequently contrasts the warmth and informality of a ソファ-centered living room with the minimalist floor-seating aesthetic of a traditional Japanese space. The term ソファセット (sofa setto) — referring to a matching sofa and armchair combination — is prominent in furniture advertising, and compact two-seater or corner-L styles are especially popular given the smaller floor plans typical of urban Japanese apartments.
