コート
コート
kooto
= coat (outerwear); also: court (tennis, basketball, etc.)
コート (kooto) is a Japanese loanword from English ‘coat’ — meaning an outer garment worn for warmth, as well as ‘court’ in sports contexts. The word illustrates one of Japanese’s loanword patterns: the same phonetic form absorbs two distinct English words (‘coat’ and ‘court’) because Japanese doesn’t distinguish the final sounds the same way English does.
Kooto (コート) has two distinct meanings: 1) Coat: an outer garment worn over other clothing for warmth or protection. Types: ダウンコート (daun kooto — down coat), トレンチコート (torenji kooto — trench coat), ウールコート (uuru kooto — wool coat), ロングコート (rongu kooto — long coat). 2) Court: a sports playing surface. テニスコート (tenisu kooto — tennis court), バスケコート (basuke kooto — basketball court). Context usually makes which meaning clear: in clothing discussions, coat; in sports discussions, court.
When コート means ‘coat,’ the typical Japanese style is コートを着る (kooto wo kiru — to put on/wear a coat) and コートを脱ぐ (kooto wo nugu — to take off a coat). In Japanese fashion vocabulary, コート covers anything from a waist-length jacket to a full-length overcoat. When visiting Japanese homes or traditional spaces, you typically remove your coat before entering (along with shoes). The sports ‘court’ meaning (テニスコート) is very common and there’s no confusion in context.
コート is written in katakana as a loanword. ‘Coat’ and ‘court’ are different English words but share nearly identical Japanese pronunciation through the regular katakana transcription rules: English /oʊt/ → コート (kooto) for ‘coat,’ and English /ɔːrt/ → コート (kooto) for ‘court.’ Japanese phonology lacks the distinction these two words have in English, so they merge into one katakana form.

Formal / Cultural context

‘Kooto’ is a Japanese katakana transcription of English ‘coat’ and ‘court,’ forming homonyms that converge because the phonological distinction of the source words does not exist in the Japanese phoneme system. ‘Kooto’ as a clothing term became established with the westernization of clothing in the Meiji era, while ‘kooto’ as a sports term became widespread with the spread of tennis and basketball in the Taisho and early Showa periods.
The Japanese fashion industry’s adoption of Western outerwear vocabulary — コート, ジャケット (jaketto — jacket), マフラー (mafuraa — scarf/muffler) — tracks the broader Meiji-era Westernization of Japanese clothing. While kimono remained everyday wear into the early 20th century, Western-style clothing progressively became standard for public and professional life. The coat in particular became a marker of modernity and education — salaried workers and students wore Western-style winter coats while manual workers retained more traditional Japanese cold-weather garments.
Japanese fashion culture has developed distinctive attitudes toward コート season. Department stores and fashion magazines mark ‘コートの季節’ (kooto no kisetsu — coat season) as a significant autumn/winter fashion moment. The first cold day when a coat becomes necessary (コートの出番, kooto no deban — coat’s turn to appear) is a seasonal milestone referenced in weather forecasts, fashion press, and casual conversation. Japan’s four-season structure makes seasonal fashion transitions culturally significant in a way that differs from climates with less distinct seasons.
