Blob of wasabi on the sushi, then ginger on top of that. Soy sauce from a packet added any old time (I buy my sushi from a supermarket). Though what you said reminded me, I used to watch a lot of J-vloggers on YouTube (Anglos and others who have settled in Japan and vlog about any aspect of it). A lot of them mix the wasabi with the soy sauce. Good wasy of doing it, really.
