# High Tension (song)

High Tension (ハイテンション, Hai Tenshon) is the 46th single by Japanese idol girl group AKB48. It was released on November 16, 2016 (2016-11-16) through You, Be Cool!/King Records. This is the final single appearance of Haruka Shimazaki, who left the group shortly after the release. The single's choreography is also centered by Shimazaki. The title song is used as the theme song of their drama Cabasuka Gakuen premiered on October 30, 2016 and was used for one of the team battles during Produce 48's group battle stage.
The single's title is an example of Wasei-eigo and refers to a state of high excitement instead of any of the usual meanings of "tension" in English.
