Harukaze Mound (Japanese: ハルカゼマウンド, Hepburn: Harukaze Maundo) is a Japanese manga series written by Togo Goto and illustrated by Kento Matsuura. It was originally a one-shot published in Shueisha's Weekly Shōnen Jump magazine 33rd issue in 2022, before being serialized in the same magazine starting in June 2025.

Plot

When they were young, twin brothers Aokaze and Nagiharu Kuzumi promised to play baseball together at Kōshien. In middle school, right-handed Aokaze, the younger brother, blossoms into a top pitching prospect recruited to Hojitsu, while left-handed Nagiharu trails in his shadow. With insight from brilliant catcher Ibuki Hayama, Nagiharu develops a completely different submarine style and follows Ibuki as a battery to a team of "outsiders" at Hinazakura High School rather than Hojitsu.

Characters

Hinazakura (Hina) High School

Nagiharu Kuzumi (P/LH)

The talented older brother, who pitches with a submarine delivery. Before adjusting his delivery on the advice of Ibuki, he used "shadow pitching" to mirror his brother.

Ibuki Hayama (C)

Captain of the Hina High baseball team. Although he led the under-12 national team as a member of the "golden generation", Ibuki's stature as "the super short catcher" and an untimely injury in middle school prevented him from drawing more attention and gave him time to study the sport. He remains a fiercely competitive athlete, with a keen eye for talent.

Yuma Hodaka (CF)

Maisuke Urushibara (SS)

"The defense ninja" who has remarkable reflexes and reaction time.

Kippei Wakamori (2B)

Initially dismisses Nagiharu as "discount Aokaze"; he is "the defense artisan" who is skilled at fielding and throwing with great accuracy.

Satomi Kikunaga (3B)

Attractive and popular; he is a mercurial hitter who pulls through in the clutch.

Kengo Yanagi (1B)

Serious and helpful; he played middle school baseball in Chiba at the affiliate of Ryokusen High School, and intended to continue to the high school there, but his swing, which impressed Ibuki, failed to develop as intended.

Extremely fast and athletic. One of two players not recruited to Hina.

After watching a perfect game in the final at Kōshien, twins Aokaze and Nagiharu Kuzumi promise to play together there. By the time they are in middle school, Aokaze has developed into an elite pitcher, while Nagiharu trails with poor control, despite his mimicry of his younger brother's form, mirrored for a left-handed pitcher. A new catcher, Ibuki Hayama, challenges Aokaze to unleash his full talent, revealing a yawning gap between the brothers; Ibuki also convinces Nagiharu to try a submarine delivery, showing the gap was self-imposed. Aokaze is recruited to perennial power Hojitsu High School, while Nagiharu follows Ibuki to a new team of "outsiders" starting up at Hinazakura ("Hina"). After intense offseason training, including skipping stones on the river, Nagiharu and Ibuki meet their teammates at Hina, including calm batter Kappei Wakamori, whose initial dismissal of Nagiharu is shaken after whiffing on the first pitch. Although Wakamori tips Nagiharu's second pitch foul, the third pitch rises up dramatically, earning him a strikeout and Wakamori's respect. This is the first year that Hina is co-ed, thanks to the baseball team; as the season starts, Captain Ibuki announces their first practice game is against Shisen Gakusha, a top-four team in the East Tokyo district. In the game, Shisen Gakusha's first-year Ataru Yoshizawa hits a home run off a nervous Nagiharu's first pitch; Ibuki and Wakamori advise him to settle down. As the game continues, Shisen Gakusha continues to collect singles but no runs as the combination of Urushibara and Wakamori turn double plays. As Ataru suspects, Ibuki had planned to let Nagiharu throw pitches that result in grounders. In the 7th inning, with two on and two out, mercurial Hina batter Satomi hits a three-run home run off a split-finger fastball, having previously claimed to being patient in waiting for a favorable pitch; Hina takes a 3-2 lead.
