Place ribs, 2 onions cut into wedges, 4 tablespoons soy sauce, star anise pods, and black pepper in a large stockpot. Add water and bring to a boil. Reduce heat to medium-low, cover, and simmer until ribs are tender when pierced, about 1 ¼ hours, stirring occasionally.

Meanwhile, heat oil in a medium skillet over medium heat. Add 1 chopped onion; cook and stir until onion is soft. Stir in honey, brown sugar, remaining 2 tablespoons soy sauce, ginger, Worcestershire sauce, and lemon juice; cook and stir until well blended. Remove from heat.

Preheat the oven to 400°F (200°C).

Remove ribs from the stockpot using tongs; arrange in a single layer in an 11x16-inch baking pan. Brush evenly with honey glaze.
