The お椀 mainly refers to the lacquered wooden bowl, primarily to the second course in the kaiseki set meal, and it is a light soup dish that highlights the original taste of the material.
There is a saying in Japanese cuisine that "Owan and Sashimi are flowers of the cuisine," which means that the chef's strength can be seen in the Owan(which means broth) and sashimi.
In kaiseki cuisine, the word お造り is used more often than 刺身(Sashimi).
