The Serena Executive Lounge was a bar and executive lounge in Kabukicho, Tokyo, Japan which was founded by Reina Tsuru during the 1980s. It became a popular hangout for yakuza members and associates such as Kazuma Kiryu, Akira Nishikiyama, and Jun Oda, but Reina was murdered in 2005, causing the bar to become derelict. In 2006, Kiryu used the abandoned bar as a hideout during the war between the Tojo-kai and Omi Alliance, but it was bought and reopened by Mariko Date in 2007 as "New Serena".
