Determine whether your 680 grams hanger steak has been trimmed at the butcher or not and trim it as needed (see "how to prepare hanger steak?" in the FAQ)

To prepare the teriyaki sauce, add the ¼ cup soy sauce, ¼ cup sake, and ¼ cup evaporated cane sugar to a saucepan and bring it to a boil. Adjust the heat down to prevent it from boiling over, and cook the sauce until it starts to thicken (3-4 minutes)

To cook the steaks, heat a grill pan over medium-high heat until it is hot. Place the steaks in the pan and cook one side undisturbed until you have nice grill marks on it. If you're using a frying pan, you want to let it go until it's nice and browned on one side.
Flip the hanger steaks over and grill the second side until you have nice grill marks. Use an instant-read thermometer to check for your desired doneness.
If you're going to continue cooking the steaks, I recommend flipping them over and turning them 45 degrees. Then you can continue grilling them until they reach your desired internal temperature.
When the beef teriyaki is cooked to your liking, remove them from the grill and let them rest for 10 minutes. This allows the meat juices to redistribute, keeping your steaks nice and juicy.
After they've rested, slice the steaks against the grain and serve drizzled with teriyaki sauce and garnished with Black sesame seeds and 1 scallion.
