Shiogai: The Rapid Rise of a Japanese Football Talent
The journey of a professional athlete is rarely a straight line, but for Shiogai, the trajectory has been one of explosive growth and rapid ascent. From struggling to find playing time in youth academies to signing with one of Germany's top-flight clubs, Shiogai's career serves as a testament to resilience and clinical finishing.
The High School Breakthrough
Shiogai's early years were spent with Buddy SC Koto (U-12) and the Yokohama FC U-15s. However, his time at Yokohama FC was challenging; he saw limited playing time and failed to secure a promotion to the U-18 squad. It was not until he joined Kokugakuin University Kugayama High School that his potential truly ignited.
By his third year, Shiogai had risen to become the team captain. He captured national attention in late 2023 during the Tokyo preliminaries for the All Japan High School Soccer Tournament. His ability to deliver in high-pressure moments was evident, culminating in a brace (two goals in a single match) against Teikyo High School to secure qualification for the national tournament.

During the 2023 national tournament, Shiogai continued his strong form, scoring in the opening match against Kindai Wakayama. Although his team eventually fell to the champions, Okayama Gakugeikan, in a 5–3 penalty shoot-out following a 0–0 draw, Shiogai's individual brilliance was undeniable. He was named one of the 36 best players of the tournament and selected for the Japan High School squad of the year.
Following this recognition, he represented the national high school squad in the "FUJIFILM Super Cup Next Generation Match" against Yokohama F. Marinos U-18s, where he scored twice. He also competed in the Denso Cup Challenge and the U-19 Youth Soccer Tournament in Düsseldorf.
University Success and Professional Debut
In 2023, Shiogai enrolled at Keio University, where he balanced his athletic ambitions with studies in the Department of Political Science, Faculty of Law. On the pitch, he was a focal point of the attack, wearing the number 10 in his first year and switching to number 9 in his second. His impact was immediate, netting 15 goals in his first league season and helping Keio earn promotion to the 2nd division of the Kanto University League.
His collegiate success caught the eye of Yokohama F. Marinos. On January 25, 2024, the club announced him as their first signing for the 2027 season. To accelerate his development, he was registered as a specially-designated player—a program allowing university students to participate in professional J.League competitions.
Shiogai made his professional debut on April 10, 2024, appearing as a substitute in a 2–0 victory over Gamba Osaka. He quickly earned a starting role, scoring his first professional goal in the 21st minute of a subsequent match against Shonan Bellmare.
European Transition: NEC and VfL Wolfsburg
Shiogai's rise continued beyond Japan. On August 28, 2024, he moved to the Netherlands, signing a four-year contract with NEC. This move allowed him to join fellow Japanese players Koki Ogawa and Kodai Sano in the Eredivisie.
His tenure in the Netherlands served as a springboard to the Bundesliga. On January 20, 2026, Shiogai signed a four-and-a-half-year contract with VfL Wolfsburg, marking his entry into one of the most competitive leagues in the world.
