Ryota Nagaki (永木 亮太, born June 4, 1988) is a Japanese footballer who plays as a midfielder for J1 League club Shonan Bellmare.

[5] He took the number 41 shirt and made his league debut for Shonan in July 2010, coming on as second-half substitute in 1–0 defeat to Kashima Antlers.

[11][12] Nagaki started his career with Kashima in impressive fashion, making 45 appearances across all competitions which included the team winning both the J1 League and the Emperor's Cup.

Kashima impressively ended up as runners-up in the competition, beating Auckland City FC, Mamelodi Sundowns and Atlético Nacional on their way to a gutsy extra-time defeat in the final against a star-studded Real Madrid team.

[16] They did win some silverware though, with a 3–2 victory over Urawa Red Diamonds in the Japanese Super Cup – Nagaki being used as a second-half substitute.

[18] Nagaki scored his first goal in a continental competition, turning in a ball across the box from Atsutaka Nakamura, but it was not enough in eventually falling to a 2–1 defeat to Brisbane Roar.

The 2018 AFC Champions League was much more fruitful for Kashima, as they won the competition for the first time in their history after a 2-0 aggregate win over Persepolis.

[23] In September 2016, Nagaki was called up to the national team as manager Vahid Halilhodzic wanted to give an opportunity to players to check the quality of their play.
