[1] He started to play with local club, Shonan Boys from his Fujisawa Zengyo Middle School days [1] and as a middle-school junior experienced the final of the Giants Cup in 2007.

[10] On June 17, Shūhei hit his first pro home run, the winner, at the Kyocera Dome off the pitching of then Orix Buffaloes righty, Hayato Terahara.

[13] In 2013, due to an injury to Dominican 3rd baseman, Hector Luna, Takahashi was given the chance to state his credentials in his preferred position for the last half of the season.

[13] On August 1 in a game against the Hanshin Tigers at Koshien Stadium, Takahashi became the youngest player in Chunichi history to hit a come from behind grand slam.

[17] Following that set-back, Takahashi was deployed in the Western league at either third base or short-stop, and, as with the previous year, made his return to the first team with an injury to Luna.

In the off-season he along with team mates Tomohiro Hamada, Iori Katsura, Shota Tomonaga and Junki Kishimoto were loaned to the Taiwanese winter league[20] where Shūhei averaged .254 with 2 home runs.

[21] With the release of Hector Luna in the 2015 off-season, Shūhei was all but guaranteed third base and took his place in the starting day line-up,[22] batting 7, against the Hanshin Tigers.

[13] After Ryosuke Hirata's injury early in the season, due to superb batting form, Shūhei was elevated to number 3 in the line-up.

However on April 30, Shūhei broke a bone in his wrist while playing against the Hiroshima Carp where he had to be substituted mid-game and as such was de-registered from the first team the following day.

Shūhei started the 2017 season on with the farm team, but was called up on 4 May quickly to replace Alex Guerrero at third-base against the Hiroshima Toyo Carp following the Cuban slugger's 2 errors the previous game.

[35] Shūhei shares the same hometown as teammate Shinnosuke Ogasawara and the two attended the same elementary school and played at the same junior baseball side Shonan Boys.

[38] On January 4, 2017, it was announced that Takahashi had married local Aichi office worker, Yuri, following a 4-year relationship, with plans to hold a wedding ceremony at the end of the 2017 season.
