Over medium heat, add the soy milk, kombu dashi and soy sauce to a small pot and stir to combine. Once the broth starts to boil, reduce the heat to simmer. Add the rice, mushrooms, yuba, green onions and spinach. Stir everything to combine.
Turn off the heat, cover the pot with the lid and let it rest for 5 minutes to let it thicken. Serve and enjoy!
