The are a professional baseball team in Japan's Pacific League based in Chiba City, Chiba Prefecture, in the Kantō region, and owned by Lotte Holdings Co., Ltd.. The Marines were a founding member of the Pacific League in as the Mainichi Orions when the Japanese Baseball League reorganized into Nippon Professional Baseball. Since 1992, the Marines' home ballpark has been ZOZO Marine Stadium, located in the Mihama Ward of Chiba, seating 30,118 people. The "Marines" name originates from the name of the stadium they play in, which is officially named Chiba Marine Stadium, because the stadium is located right on the water. Through 2022, the franchise's all-time record is 4733-4701-394 (.501). History The Marines franchise began in 1950 as the Mainichi Orions, an inaugural member of the Pacific League. The Orions were named after the constellation of the same name. The Marines won the inaugural Japan Series in 1950. In 1958, the team was merged with the Daiei Unions and renamed the Daimai Orions. In 1964 they became the Tokyo Orions, and the Lotte Orions in 1969. The franchise was slow to replicate its initial success: the Orions made the Japan Series in 1960 and 1970, only to lose both years. The team played in central Tokyo until 1972. From 1973 to 1977 the Lotte Orions played in the northern Japanese city of Sendai. In 1974, they beat the Chunichi Dragons, becoming the first Pacific League team to win the Series in ten years, as the Yomiuri Giants had claimed the prior nine titles behind the Oh–Nagashima attack. After beating the Dragons, their owners, Lotte Holdings, decided to hold their victory parade in Tokyo, which shocked fans in Sendai. This eventually caused their attendance there to crash, from sold out games in 1973, to only about 2000-3000 for their last few years in Sendai. In 1977, the Orions signed Major League Baseball player Leron Lee, who ended up playing for the team for eleven seasons, compiling a .320 career batting average and slugging 283 home runs with 912 career RBI. From his retirement to early 2018 (when surpassed by Norichika Aoki), Lee held the Japanese record for career batting average (players with more than 4,000 at bats). In 1978, Lee invited younger brother Leon Lee to play in Japan, and the brothers formed a feared cleanup for the Orions for five seasons — in 1980, Leron had 33 home runs,
