Bring a large pot of salted water to a boil, add the soba noodles, and cook for 3-4 minutes, stirring constantly to prevent sticking, until just tender. Drain and refresh under cold running water. (You must rinse the noodles in cold water immediately to keep them from sticking, people.) Place the noodles in a large bowl and toss with the olive oil to keep them loose. Refrigerate for at least 1 hour to chill.
To make the dressing, mix together the ginger and garlic in a small bowl. Add the remaining ingredients and whisk everything together. Season with salt and white pepper.
Roughly chop or tear the herb leaves and add them to the bowl of chilled noodles with the green onion, seeds, and dressing. Toss gently to combine and season with salt and white pepper to taste.
