Add the ½ cup soy sauce, ½ cup sake, ⅓ cup mirin, 40 grams evaporated cane sugar, and smashed 1 large clove garlic to a pot and bring to a boil. Lower the heat to keep the pot from boiling over, and cook the sauce until the bubbles become big and glossy and the sauce has reached a temperature of 230 degrees F.

Sprinkle the 450 grams pork belly evenly with the ¼ teaspoon salt.

Heat a large frying pan over medium-high heat until very hot and then add the pork in a single layer (you may need to do this in batches). Fry until the pork has slightly browned on one side, and then flip it over and fry the second side.
Transfer the pork to a plate and repeat until all of the pork has been fried.
Wipe out the oil from the pan after the last of the pork has been fried.
Add ¼ cup of the sauce to the pan and reduce until the sauce is very thick and viscous and then return the pork to the pan. Flip the meat around several times until it is glazed with the sauce.
Transfer the pork to a wire rack set over a heat-proof tray. Use a kitchen torch to brown the glaze and meat until it is lightly charred around the edges.
To assemble the pork bowls, add 2 servings cooked short-grain rice to two large bowls. Drizzle a tablespoon or two of sauce around the rice. Arrange the grilled pork on top of the rice. Garnish with 1 scallion.
