SP (2007–2008) | Kaiko Hiroba Park — Inoue’s Childhood Trauma and the Yamanishi Bench

Kaiko Hiroba Park (開港広場公園) in Yokohama is one of『SP(エスピー)』’s most important recurring real-world locations. The National Filming Location Guide identifies the square as the place where the violent incident from Kaoru Inoue’s childhood occurred, and episode 8, broadcast December 22, 2007, returns there in flashback. The same park is then used in episodes 8 and 9 for Inoue and Kazuya Yamanishi sitting together on a bench, tying the present investigation back to the trauma that shaped Inoue.

The park still exists beside the Yokohama Archives of History. Yokohama’s current city materials describe it as the site associated with the signing of the Convention of Kanagawa and list it at Yamashita-cho 1 / Nihon-odori in Naka Ward. The stored 35.44726, 139.64427 point is a park-level map coordinate based on the present park footprint, not a claim about the exact bench, childhood-event mark, or camera position. It is a public urban park, but visitors should respect ordinary park users and the adjacent historic facilities.
