Ura Maki  refers to Japanese inside out Maki rolls which means the rice is on the outside of the Nori wrapper. 

Ura Maki is very different from the traditional Maki as the vinegared rice is on the outside of the sea kelp wrapper known as Nori in Japanese.  

Maki are layers of raw or cooked fish or shellfish, vegetables and vinegared rice wrapped on a sheet of dried sea kelp (Nori)  rolled into cylinder shape  then cut into pieces
