Because it's a Probox from Toyota. I like how Tomica made it to look like an official TOMY delivery vehicle.
Not much is known about it aside from being introduced by Toyota for the Japanese market in August 2002. It is a small station wagon designed for commercial use as a delivery vehicle.
It is used with a left-hand drive conversion extensively as a taxi throughout Peru, Bolivia and as right-hand drive in Myanmar (particularly in Yangon where the streets are inundated with Probox taxis.) (Source: Wkikpedia)
Leave to Tomica to make an obscure Japanese vehicle that we've never heard before, even more if its name sounds like a gaming console.
The hatch opens to reveal a couple of stacked boxes inside, a very nice touch. Yo dawg, I heard you like boxes...
