The Japanese dish combining tempura with soba and pictured on Wikipedia as tempura and soba is tenzaru.
Tenzaru, also called tenzaru-soba or ten-seiro, pairs chilled soba noodles with tempura served separately. The noodles are usually placed on a bamboo tray or similar draining stand, while the tempura comes on its own plate; both are eaten with a dipping sauce. The name combines “ten,” from tempura, with “zaru,” the traditional bamboo tray associated with chilled soba.
This arrangement differs from hot tempura soba, or tensoba, in which tempura is served with soba in a hot broth. Both dishes combine the same broad elements, so menus and regional naming can cause confusion. The key distinction is the cold, separately served noodle-and-tempura presentation.
Soba became especially popular in Edo-period Japan, where noodle shops and food stalls helped make it an everyday meal. Tempura and soba are both associated with Edo cuisine, and their combination remains a classic Japanese restaurant dish.
