The "Tora Tora Platinum" series consists of numerous volumes released primarily in the late 2000s (roughly 2007–2009).
It was released in 2008 as part of a series often categorized as adult or variety entertainment.

Actresses signed to Tora Tora Platinum were marketed like mainstream celebrities—with fan events, photobooks, behind-the-scenes documentaries, and even soundtrack CDs.
