The following year the Hawks also won the 2018 Japan Series against the Hiroshima Carp in six games, making it back to back titles for a second time, and four out of the last five; the next year, they became the first team to win three straight Japan Series titles since the Seibu Lions did it from 1990 to 1992, by sweeping the Yomiuri Giants. In 2020, the Hawks won the 2020 Japan Series, again in four games against the Yomiuri Giants, becoming the first team to win more than three consecutive Japan Series titles since the Yomiuri Giants won the last of nine consecutive titles in 1973.
