Green onion seaweed seiro soba, Ōita, Japan

Cold buckwheat soba noodles with green onions and seaweed in Ōita, Japan. …

Zaru soba, mori soba, and seiro soba are all cold buckwheat noodles with slight variations on how they are served and quality of the noodles. Might be difficult to tell them apart, but all good to me!
