Shuma Nagamatsu joined Ruch Chorzów as a free agent after his contract with Korona Kielce ended last season. He signed a one-year contract with an option to extend for another year. The player was determined to join Ruch Chorzów despite having other offers.

Ruch Chorzów is in the process of completing their third summer signing with Shuma Nagamatsu, who has been recognized for his performances at Znicz Pruszków and Korona Kielce. Korona Kielce had previously confirmed that Shuma Nagamatsu's contract would not be renewed. Seizing this opportunity, Dawid Szulczek's team transitioned from initial interest to taking action, and Piotr Koźmiński reported that it is now certain. The Japanese player is set to become the third addition to Ruch Chorzów's squad, barring any unforeseen circumstances, which are considered unlikely. The 29-year-old, who plays as an attacking midfielder or winger, did not have a successful stint in the Ekstraklasa, featuring only 17 times in the last season and managing to score a goal and provide an assist. He had previously found success at Znicz Pruszków in the I liga, and his first Polish club was Świt Szczecin.

After his departure from Korona Kielce, Shuma Nagamatsu is garnering interest from Ruch Chorzów. Previously, he was a standout player at Znicz Pruszków in the I liga, where he scored ten goals and provided five assists during the 2023/2024 season. Despite interest from Ekstraklasa teams, Nagamatsu struggled to make a significant impact at Korona Kielce, primarily serving as a substitute. Korona Kielce has announced that they are parting ways with him after less than a year, and he is expected to remain in Poland. Ruch Chorzów, in search of reinforcements for the upcoming season, has shown interest in Nagamatsu, as reported by Dominik Pasternak of TVP Sport. Although offers from Ekstraklasa are unlikely, he may pursue promotion prospects with Ruch Chorzów.
