Considered one of the best prospects in FC Tokyo's youth ranks, he first joined the first-team squad from the 2011 J.League Division 2 season.[1] He didn't manage to amass much playing time in the squad, so Hashimoto was loaned to Roasso Kumamoto for the 2013 and 2014 seasons.[2]
Rostov
On 9 July 2020, Russian Premier League club FC Rostov announced that they had reached an agreement with FC Tokyo for Hashimoto's transfer, and he would move pending a medical. The Japanese footballer signed a 4-year contract with Rostov after arriving in Russia and completing the medical exam.[3] On 23 August 2020, he scored his first goal for Rostov to secure a 1–0 away victory over FC Ufa.[4] In their next game 3 days later he once again scored the only goal of the game to beat FC Ural Yekaterinburg 1–0.[5]
On 19 February 2021, Rostov removed Hashimoto from their official squad as registered with the league. That was expected to be temporary, as Russian clubs are only allowed to have 8 foreign players registered at the same time, and Hashimoto was injured at the time.[6] He was returned to the squad list on 24 February after the loan of David Toshevski freed up a foreign player spot.[7]
Loan to Vissel Kobe
On 27 March 2022, Hashimoto returned to Japan and signed for Vissel Kobe firstly on a three-month transfer from Russia's FC Rostov after a FIFA ruling temporarily freezing the contracts of foreign players signed with Russian clubs and allowing them to go elsewhere.[8] On 1 July 2022, his contract was officially extended for an undisclosed period.[9]
Huesca
On 18 July 2022, Hashimoto signed with Huesca in Spain.[10] On 3 September 2023, Hashimoto returned to Huesca on a permanent basis and signed a two-year contract.[11]
Eibar
On 29 August 2024, Hashimoto signed a one-year deal with Eibar also in the Spanish Segunda División.[12]
