Ares was a bar located on the top floor of the Millennium Tower in Kabukicho, Tokyo, Japan. It was founded shortly after the tower's completion, and yakuza boss Shintaro Kazama installed Yumi Sawamura as the bar's proprietor under the alias "Mizuki" to provide her with a livelihood and alibi as her ex-lover Kyohei Jingu sought to murder her and their child Haruka Sawamura. In 2005, the bar was used by Kazama and Sawamura to hide the ¥10 billion stolen from the Tojo-kai.
