This is not a Toppola, but maybe its predecessor. A Toppola is more something like this.
It is the best combination of a camper and a Saab hatch (call it 99, 900, 9000 or 9-3). This intelligent idea seems to have some fans in Japan, but they have used another car as basis.
The Japanese company called Camp-Inn has presented at the current Tokyo Auto show a modern version of the Toppola using a Toyota Prius as the basis. This add-on for the Prius is called Relax Cabin.
Look at the pictures and decide by yourself if this is a worthy successor of the Toppola.
Remember this is a product for the Japanese market where sometimes the Hotel rooms are slightly smaller than this. 😉
