Okay, so it looks like our main character eats her egg on the side, but the cookbook recipe was for the raw egg in the rice, so I did both. And of course, miso soup. Ready to start the day!
Tamago kake gohan (卵かけご飯, "egg on rice") is a popular Japanese breakfast food consisting of cooked Japanese rice topped or mixed with raw egg and soy sauce.
It's also really tasty, and egg production is extremely well regulated in Japan, so there really isn't a risk of raw eggs being dangerous to eat there. For people with their own chickens, this also isn't a problem, as you'd likely know if your bird was sick.
