ナイター

night + -er is the English-looking base of ナイター. Digital Daijisen labels it as 和, "night plus -er," and Seisenban Nihon Kokugo Daijiten treats nighter as a loan-style form. Its early printed example is from Inoue Tomoichiro's Odan Hodo in 1956: a line about a baseball ナイター somewhere that night. The same entry marks it as a summer season word in haiku. The word belongs to postwar sports and broadcasting vocabulary. Britannica notes that Major League Baseball's first night game was on May 24, 1935, at Crosley Field in Cincinnati. Japan's first professional baseball night game was on August 17, 1948, at Yokohama Gehrig Stadium, Yomiuri Giants versus Chunichi Dragons. ナイター then lined up with ナイトゲーム and デーゲーム in baseball reporting. TV schedules in the Showa period helped keep the short form common. Modern Japanese uses ナイター for baseball, soccer, tennis, ski events, and other games held under lights. In ordinary English, "night game" or "game under lights" is natural; "nighter" is not the usual noun for a sports match. English has "all-nighter," but that means staying awake all night, not a game. The Japanese -er ending makes the word sound English without matching common English usage. Example: 今夜はナイターを見る.
