Wash rice, and strain. Set aside.
In a pot, combine Azuki red beans and 2 cups of water. Bring to a boil for 2 minutes, then strain. Return the beans to the pot with 3 cups of water and simmer on low heat for 45-50 minutes.
Strain the beans, but retain the cooked water this time. Add additional water to the cooked water to make a total of 4 cups of liquid.
In the pot, combine the rice, cooked beans, and salt, and add the liquid. Cook on low heat for 30-40 minutes.
