Video of a sushi restaurant in Aichi prefecture that is famous for its ridiculously oversized sushi:
It’s mega sushi roll has 20 different foods wrapped inside 2 meters of seaweed and rice. It costs 15,000 yen and requires a reservation 2 days in advance.
For the same price, you can also order a giant set of nigiri sushi (together with a super tiny set). The slab of tuna on top of one blob of rice could make about 40 normal-sized maguro nigiri-zushis.
