Cut the tofu, pork belly and onion into bite-sized pieces.
Stir fry the pork belly. Don't add too much cooking oil here; try to draw out the fat in the pork belly.
When the meat is cooked and the fat is coming out, add the onion and sauté together.
When the onion is cooked add the water, soy sauce, mirin, sugar and dashi powder. When it comes to a boil add the tofu.
When it comes to a boil again, simmer for 1 minute, then it's done.
If you let it cool down once and then reheat it, the flavors will be absorbed into the ingredients and the dish will taste even better.

It's best if you don't simmer it for too long after adding the tofu.
