Ingredients
3/4 cup soy sauce
3 tablespoons sake
4 teaspoons mirin (Japanese sweet rice wine)
3 tablespoons dried bonito flakes
11 ounces soba noodles (about 3 bundles)
1/2 sheet toasted nori, cut into matchsticks (optional)
1 piece (6 inches) daikon radish, peeled, finely grated, and squeezed of excess juice
Shiso leaves

Preparation
Make the dressing: Cook soy sauce, sake, mirin, and 2 tablespoons water in a medium saucepan, stirring occasionally, over medium heat until bubbling, about 4 minutes. Add bonito flakes. Remove from heat, and let cool completely. Pour through a fine sieve into a small bowl; discard bonito flakes.
Bring a large pot of water to a boil. Add noodles; cook according to package instructions, about 5 minutes. Drain, and rinse under cold running water.
Arrange noodles in 4 serving bowls; drizzle each with 1 tablespoon dressing. Arrange nori, radish, shiso leaves, radish sprouts, and tempura crumbs around bowl. Serve with remaining dressing.
