West Park is a park in northeast Kabukicho, Tokyo, Japan. It was laid out as a public green space, and the head planner at the Tokyo Bureau of Construction erroneously named the park "West Park" on a map; it was not until four years later that someone pointed out the error, but, by then, the name had stuck. It also served as Kabukicho's subway access point for years, but the subway closed in the 1980s, and the park fell into disuse and became the site of a large homeless encampment. From 2005 to 2006, Majima Construction demolished West Park to make way for Kabukicho Hills, and the homeless population was moved to Dragon Palace and to a number of underground sewers. After Kabukicho Hills was demolished in 2006, all that was left of the former West Park was a concrete pad with a builder's hut and the entrance to an underground secret pleasure district called "Purgatory", which had been founded by the Florist of Sai during the 1990s. In 2009, construction on the Kabukicho Hills project resumed.
