Before 1979, they were based in Fukuoka in Kyushu. The team is owned by a subsidiary of Prince Hotels, which in turn is owned by the Seibu Group.

Between 1978 and 2008, the team logo and mascot were based on the adult version of Kimba the White Lion, a classic Japanese anime series by Osamu Tezuka.

Document 3: List of knuckleball pitchers: Knuckleball pitchers are baseball players who rely on the knuckleball as their primary pitch, or pitch primarily based on their ability to throw a knuckleball. The inventor of the knuckleball has never been established, although several pitchers from the early 20th century have been credited. Baseball statistician and historian Rob Neyer named four individuals in an article he wrote in the 2004 book "The Neyer/James Guide to Pitchers" as potentially deserving credit, any of whom may have originated the pitch in either the 1907 or 1908 seasons. Nap Rucker of the Brooklyn Dodgers came up to the majors in 1907, initially throwing hard stuff but later switching to the knuckleball. A 1908 article credited Lew Moren as the inventor of the pitch. Ed Cicotte earned a full-time spot with the Detroit Tigers in 1908, earning the nickname "Knuckles" for his signature pitch. A picture of Ed Summers showed him gripping what he called a "dry spitter" using a variation of the knuckleball grip using the knuckles of his index and middle fingers.

Document 13: Cutter (baseball): In baseball, a cutter, or cut fastball, is a type of fastball which breaks slightly toward the pitcher's glove side as it reaches home plate. This pitch is somewhere between a slider and a fastball, as it is usually thrown faster than a slider but with more motion than a typical fastball. Some pitchers use a cutter as a way to prevent hitters from expecting their regular fastballs. A common technique used to throw a cutter is to use a four-seam fastball grip with the baseball set slightly off center in the hand. When a batter is able to hit a cutter pitch, it often results in soft contact and an easy out, due to the pitch's movement keeping the ball away from the bat's sweet spot. The cutter is typically 2–5 mph slower than a pitcher's four-seam fastball. In 2010, the average pitch classified as a cutter by PITCHf/x thrown by a right-handed pitcher was 88.6 mph; the average four-seamer was 92.1 mph.
