If you have eaten sushi you probably experienced the conveyor belt that carries the sushi plates around the counter at kaiten-sushi (回転寿司) chains. Then there are the stores, particularly some overseas stores, that have a train carrying the plates around a track instead of the conveyor belt.
Epoch Co. (エポック社) have come out with a toy train set that can carry sushi around a track for the kids to play with at home. The company has a previous train product that did very well and is currently selling a cooking toy. They decided this sushi train N700 series product would combine the success of these other two.
The train is modelled on the N700 series Shinkansen and comes complete with toy sushi blocks. You can change those over for real sushi but it might need to be small sized !

The product is due to come on to the market at the beginning of July and will be available through Amazon Japan as well as other outlets. I cant find any information for English sites yet.
It is going to be on sale for about YEN 5,000
