Japanese Mushroom Rice

Hello, here is my version of mushroom rice. I tried yesterday, yummy at the first try, so have to share this hehehe....
Ingridients:
1 packet Shitake mushroom (thinly slice)
1 packet Maitake mushroom (cut small)
1 packet white button mushroom (thinly slice)
You can also add your favorite mushroom eg. enoki, abalone mushroom (according to what's available in the supermarket off course). Plus for more flavour, you can add bamboo shoots and some chicken wouldn't hurt also.
4 to 5 tbsp soy sauce (or to your taste)
4 tbsp sesame oil (as long as thinly cover your pan)
salt, pepper, sugar to your taste
2 tbsp mirin (japanese cooking wine, can use sake also)
2 cup of Japanese rice , washed
2.5 cup of chicken stock (I use canned chicken stock --> unless you want to torture yourself boiling the real chicken) --> ratio 1 cup of rice : 1.25 cup of stock
How to cook:
1. heat up sesame oil on the pan and sautee all the mushrooms until half-cooked
2. add mirin and seasonings, then sautee until cooked thoroughly
3. on the rice cooker, place the rice and the chicken stock, then add the sauteed mushroom on the top, stir a bit, and on the rice cooker
4. the rice cooker tick off --> voilla there's your mushroom rice
