Prepare the sushi rice by folowing the recipe link.
Soak the mushrooms in a bowl with 1 cup of water. Soak Kanpyo in a separate bow with 1 cups of water.

Prepare the tamagoyaki by following the steps in the recipe link then cut into long sticks.
Squeeze out the excess water from the mushrooms into a bowl (save the water) and slice them thinly.
Squeeze out the excess water out of the Kanpyo and cut them in same length of nori sheets.
Put 100ml of the water that the mushroom soaked in and 2 tbs of sugar, 2 tbs sake, and 2 tbs of soy sauce into a saucepan.
Put the sliced mushrooms, Kanpyo and carrots into the sauce pan and bring it to boil then reduce the heat to low and allow it to simmer until the most of the liquid has reduced and the carrots are soft.
Remove from heat and allow to cool down before putting into the sushi roll.
Lay a seaweed sheet onto a sushi mat and place 1.5 cup rice on top and spread it out about 5mm thick leaving 3cm(1.2 inch) gap at the one edge of nori sheet.
Lay out the fillings in the centre of the sushi rice. Do not layer them on top of each other fillings, rather line them up. *3
Place a little water on to the larger edge of the seaweed then roll the other side towards it and press down on the fillings as you roll then squeeze tightly.
Repeat for the remaining amount of rice and fillings.
Cut the sushi roll into smaller sizes and serve with Sushi ginger and Wasabi if you have. *4
