Planetokio (known in Japan as Tokyo Wakusei Planetokio) is an role-playing action-adventure video game series created by Osamu Sato during his tenure at OutSide Directors Company for Asmik Ace Entertainment. The first two titles, published by Asmik Ace Entertainment in Japan, were originally exclusive to the Sony PlayStation. Since its conception at OutSide Directors, the series has appeared on multiple platforms and gone through various developers and spans numerous genres. None of the other titles involve the participation of Osamu Sato.

The games are mostly set in a near future and more specifically in Planetokio, which it is a number of floating cities full of life like the old Japan. The city is attacked by the Collect Aliens that got a personal shield that allows them to receive no harm. The protagonist of the series is a blue-haired boy named Iken, whose peaceful life in Planetokio is often interrupted by alien robots and monsters. In most games, Iken must defeat the aliens and foil any world domination plans.
