This should be Nakamura and Hosoi scene. Though since this isn't the full scene I'm not 100% sure if any of the cuts here are nakamura's but since the first cut doesn't look like hosoi at all to me and the rest does I'm going to assume that nakamura did the first cut and the cuts before it while hosoi did the rest of the scene.
