Using a box grater's finest holes, grate the onion directly over a small bowl, capturing both the pulp and juice. This will dissolve into the sauce for subtle sweetness.
Slice the cabbage into thin shreds, keeping them uniform for even texture. Cut the tomato into wedges, removing any tough core pieces.
Combine ponzu, sake, and soy sauce in a medium bowl, whisking until smooth. The sake will cook off, leaving the ponzu's citrus brightness intensified.
Blot the pork chops completely dry with paper towels — any surface moisture will prevent proper browning and cause the flour to clump.
Score shallow cuts through the connective tissue where the fat meets the lean meat on both sides. This prevents the chops from curling as they cook.
Season just one side of each chop with the salt and pepper, pressing gently so the seasonings adhere to the surface.
Dust both sides of the seasoned chops with flour, then shake off any excess. The light coating helps create a golden crust and thickens the final sauce.
Preheat your frying pan over medium-high heat until a drop of oil sizzles immediately. Add the oil and swirl to coat the bottom evenly.
Place the pork chops seasoned-side down first and cook undisturbed for 4 minutes per side until deep golden brown. Resist the urge to move them early.

Pour the ponzu mixture and grated onion directly into the pan around the chops. The liquid will bubble vigorously at first.
Tilt the pan and use a spoon to baste the sauce over the meat repeatedly, coating each chop thoroughly as the sauce reduces and darkens.
Move the glazed chops to a cutting board and slice them into bite-sized pieces, cutting against the grain for tenderness.
Arrange the sliced pork alongside the fresh cabbage and tomato wedges. Finish with a sprinkle of chopped parsley for color and freshness.
