Hi again, Dena! I've been looking around the web and I haven't seen anything yet, but I'm pretty sure the sugar is what gives it the sweet flavor and the coating on the outside.
I would be interested in making this without sugar as well so I'll try a few things myself and get back to you.
In the meantime you could try substituting white for brown, that's what I usually do when a recipe calls for white and it's never failed me.
ACTUALLY- I just found a recipe using "organic sweet brown rice, filtered water, hemp seeds, pumpkin seeds, flax seeds, black sesame seeds, poppy seeds, sunflower seeds, and sea salt.". I'm assuming they grind the seeds together until it's like that grainy sugar and roll it in that, but they didn't list directions. Apparently mochi is simply brown rice pounded into a cake.
If you're feeling experimental you can try that. I'm going to keep digging and maybe try a few things myself and I'll get back to you asap.
