Sakura Taisen 4: Koi seyo, Otome ("Sakura Wars 4: Fall in Love, Maidens") is the fourth entry in the strategy RPG/dating sim series, Sakura Taisen, which was developed by Overworks and Red Entertainment. The game was published by Sega in Japan on March 21, 2002 for the Sega Dreamcast and a PC port was later released in 2007.
Sakura Taisen 4 was promoted as the "Grand Finale" of the Sakura Taisen franchise and while the series did continue after the fourth entry, Fall in Love, Maidens was the final game to feature the franchise's original cast. The game brought an end to the story of the series' hero, Ogami, and all of his relationships with the characters throughout the series were brought to a finale. The Sakura Taisen series would later be rebooted in Sakura Taisen V with a new protagonist, setting, and supporting cast.
