= tennis
Tenisu (テニス) is simply the Japanese word for tennis — a sport that has become deeply embedded in Japanese school culture, manga storytelling, and professional athletics. Japan’s obsession with tenisu goes well beyond weekend recreation.
Tenisu (テニス) is borrowed directly from the English ‘tennis.’ It refers to the sport, and Japanese has built an extensive vocabulary around it: tenisu kooto (テニスコート, tennis court), tenisu raketoo (テニスラケット, tennis racket), tenisu booru (テニスボール, tennis ball), and tenisu bu (テニス部, tennis club at school). In Japan, tennis is one of the most popular school club activities (bukatsu) alongside baseball, soccer, and badminton. The sport is also associated with romance in Japanese media — countless manga and anime series are set against the backdrop of high school tenisu bu, where training together and competition create the perfect conditions for drama and first love.
Tennis clubs (tenisu bu) in Japanese schools are a significant commitment — members typically practice every day after school and on weekends. Joining a school sports club isn’t casual in Japan; it’s a full social structure with strict senpai-kohai hierarchy (senpai = upperclassmen, kohai = underclassmen) and elaborate club rituals. If you encounter the term tafuto tenisu (タフトテニス) or sofuto tenisu (ソフトテニス, soft tennis), note that this is a Japanese variant using a softer rubber ball that is played extensively in middle schools across Japan.

Tenisu arrived in Japan in 1878, introduced by foreign instructors at what is now Hokkaido University. It spread quickly among elites and then into schools as part of physical education culture. Japan developed its own variant — sofuto tenisu (ソフトテニス, soft tennis) — using a softer rubber ball, which is now played almost exclusively in Japanese middle schools. Regular hard-ball tennis dominates high school, university, and professional play.
Japan’s global tenisu reputation rose dramatically with players like Kei Nishikori, who reached the US Open final in 2014, and Naomi Osaka, who won four Grand Slam titles between 2018 and 2021. Osaka’s success in particular sparked a national enthusiasm for tenisu at all levels, increasing youth enrollment in tennis programs. In popular culture, the manga and anime series The Prince of Tennis (Tennis no Ouji-sama) created a generation of fans who approached the sport with near-mythological intensity — the series is credited with significantly boosting tennis club membership across Japan.
