Rinse the sushi rice under cold water using a strainer until the water runs clear.
Transfer the rinsed rice to a saucepan and add 2 cups water.
Bring the mixture to a boil over medium-high heat.
Reduce heat to low, cover, and cook for 12 minutes.
Remove from heat and let the rice sit, covered, for 10 minutes to finish steaming.
Remove the lid and allow the rice to cool slightly.
In a small saucepan, combine rice vinegar, sugar, oil, and salt.
Heat over medium heat until the sugar dissolves completely, then let the mixture cool.
Pour the vinegar mixture over the cooked rice.
Gently stir to combine, allowing the rice to absorb the seasoning as it cools.
Continue mixing lightly until the rice reaches a glossy, slightly sticky texture.
Use as desired for sushi or serve as a side.
