A lighthearted satire of Japan’s postwar corporate elite, The Executive Gentleman’s Register blends farce, romance, and boardroom comedy with the polished charm of 1960s salaryman cinema. When mild-mannered secretary Tsutomu Harada’s wedding is postponed yet again due to the sudden promotion of his matchmaker, Reitarō Koizumi, to company president, chaos ensues in the world of business and matrimony alike. At a raucous nightclub party, a game of musical chairs leads to injury, scandal, and rivalry with a competing paper-bag tycoon. Limping through his first day as president, Reitarō faces corporate sabotage, eccentric clients, and a disastrously comic “business trip” that tangles together love, liquor, and misplaced ambition.
