A 1991 graduate of the University of Tokyo, he was elected for the first time in 2007. Shina was born and grew up in Morioka, Iwate before attending the University of Tokyo.

He first ran for office in a 2007 by-election following the resignation of his High School and University senior, Takuya Tasso, in Iwate's 1st district. He won in 2009 and was tapped to become a Parliamentary Vice-Minister for Internal Affairs and Communications, and served through the Kan Cabinet. Following his vote against the consumption tax raise launched by the Noda Cabinet, he was suspended by the DPJ for two months but declined to leave the party, and won in 2012 despite facing a candidate handpicked by Ichiro Ozawa to defeat him, and the strong national headwinds in favor of the LDP.

Following the defeat, Shina was shuffled throughout various DPJ party positions, serving as a shadow minister in the NEXT Cabinets of varying leaders. He won in 2014 again and merged with the DP in merging with Kibō no Tō, holding onto his district in 2017. He joined the DPP before leaving the party following the Iwate's branch decision to endorse a candidate from Ichiro Ozawa's Liberal Party. He joined the CDP shortly thereafter and fought attempts by the Prefectural Branch controlled by Ozawa to replace him as the candidate in Iwate's 1st, winning in 2021. He was appointed the Shadow Minister of Finance in the Next Cabinet's of Kenta Izumi and Yoshihiko Noda until September 2025. He won his district in 2026 after joining the CRA, becoming one of the "seven samurai" to do so.
