The Pokémotion was released on August 1, 2003 exclusively to Japan and sold for ¥2500. It is a glowstick with built in LEDs. When the user waves the Pokémotion from left to right, it projects over 200 pictures and animations into the air including Pokémon sprites, crosses/circles and katakana. The Pokémotion has four modes, including an images mode where the user can see 201 different Pokémon, a quiz mode where the player must answer questions such as "Who's That Pokémon?", a communications mode where the user can communicate with friends through messages in holograms and an illumination mode. The Pokémotion works through the use of the afterimage illusion.

The success of the Pokémotion contributed to the development of the Wii MotionPlus accessory. According to an Iwata Asks interview, there was originally a fault in the design of the peripheral, in which the Wii MotionPlus would disconnect from the Wii Remote if shaken "tens of thousands" of times. Nintendo therefore borrowed the remaining Pokémotion store displays and replaced them with Wii Remotes, in order to experiment with Wii MotionPlus and verify that the problem was fixed.
