There are many kinds of sushi that do not use raw fish such as egg (tamago), natto, cucumber rolls (kappa maki), yam, etc. However, vinegared rice is inevitable to sushi.
Something similar to sushi that does not use vinegars are onigiri - it's translated to rice ball in English. We stuff all sorts of ingredients in the center of rice made into a triangular shape. Onigiri normally does not contain raw fish and you can find those easily at convenience stores.
Omg. Raw fish and vinegar rice are inevitable for sushi.
inari sushi :)
