This is a series of gashapon (capsule toys) or trading figures depicting characters or people.
Here's a nice figure-and-vehicle set featuring JASDF cutie Rei Nakajima and her #6 Blue Impulse Jr. stunt bike, a replica of the JASDF's Blue Impulse flight demonstration team's Kawasaki T-4 aircraft, used to promote the Japan Air Self Defense Force at various events. In this version, Rei is wearing a snappy Blue Impulse helmet. Both the Rei figure and Blue Impulse Jr. are made of ABS plastic and PVC vinyl. Pre-assembled (you just need to snap in the vertical stabilizer) and prepainted, ready to display.
