Sugi was born in Saitama, and joined Kashiwa Reysol"s youth setup in 2009, aged 16.
In the 2011 summer the Spanish agent Javier Subirats decided to represent him, after a friendly match between Kashiwa and Elche CF"s reserves. However, after failing to join the Andalusians, Sugi returned to Japan to play for Sendai University until October 2012, when Gaspar Campillo, coach and sporting director of Football Club Jove Español San Vicente, decided to sign him after positive reports written by Subirats. He signed an 18-month deal with the Valencian side, but due to bureaucratic problems, was unable to play with the main squad in Tercera División, and was assigned to the B-team in the regional levels.
After Jove Español"s assignment as a farm team of Hércules CF, Sugi was called up to the latter"s first-team, by manager Quique Hernández.
Sugi made his league debut on 17 November, again from the bench in a 2–4 loss at Córdoba CF for the Segunda División championship, and scored his first professional goal seven days later, netting the last of a 3–0 home success against Civil Engineering Sabadell. On 22 December, he renewed his link with the Valencian side, signing a three-and-a-half contract with a €10 million clause, being definitely promoted to the main squad.
