U.S. measurements first, metric equivalents in parentheses. Conversions are approximate.

1. Combine ground beef, soy sauce, Worcestershire sauce, 3/4 tsp (3.75 ml) salt and 1/4 tsp (1.25 ml) pepper in a bowl; mix gently and form into four 4- to 5-ounce (142 g) patties (about 4 oz (115 g) each). Press a slight dimple in the center of each patty.
2. In a skillet over medium heat, cook bacon until crisp; transfer to paper towels and keep warm.
3. In the same skillet, add 1 tbsp (15 ml) vegetable oil if needed and sear patties 3–4 minutes per side for medium, adjusting time for desired doneness; place a slice of cheddar on each patty in the last minute to melt. Remove and rest 3 minutes.
4. Meanwhile, wipe the skillet and melt butter over medium heat; toast buns cut-side down until golden, about 1–2 minutes.
5. Fry eggs sunny-side up or to preference in the skillet; season with remaining salt and pepper.
6. Stir together mayonnaise, tonkatsu sauce and ketchup to make the burger sauce; taste and adjust seasoning.
7. Assemble burgers: bottom bun, lettuce, tomato, onion, patty with cheese, 2 slices bacon, fried egg, sauce, top bun. Serve immediately.
