1. If making dashi: wipe 6x6 inch (15x15 cm) kombu and steep in 4 cups (960 ml) cold water for 30 minutes, heat until just before boiling, remove kombu, add a generous handful (about 0.35 oz (10 g)) katsuobushi, simmer 1 minute, turn off heat, steep 5 minutes, then strain to yield dashi. Alternatively, dissolve instant dashi to total 4 cups (960 ml).
2. In a small saucepan combine 1 cup (240 ml) of the dashi with soy sauce, mirin, sake (if using) and sugar; bring to a gentle simmer to dissolve sugar, then remove from heat and let cool. For a concentrated tsuyu, this mixture is the dipping sauce; refrigerate until cold.
3. Bring a large pot of water to a rolling boil. Add soba noodles and cook according to package instructions until just tender, usually 4–5 minutes for dried soba.
4. Immediately drain noodles and rinse under cold running water while tossing to remove surface starch. Transfer to a bowl of ice water to chill thoroughly, then drain well.
5. Divide chilled noodles among 4 serving plates or zaru (bamboo trays). Pour tsuyu into 4 small individual dipping bowls; if desired, dilute tsuyu with remaining chilled dashi to taste.
6. Serve with sliced scallions, shredded nori, grated daikon and a small amount of wasabi on the side. Dip cold noodles into tsuyu and eat immediately.
