Gyūdon (牛丼), literally beef bowl, is a Japanese dish consisting of a bowl of rice topped with beef and onion simmered in a mildly sweet sauce flavored with dashi (fish and seaweed stock), soy sauce and mirin (sweet rice wine). It also often includes shirataki noodles, and is sometimes topped with a raw egg or a soft poached egg (onsen tamago). A very popular food in Japan, it is commonly served with beni shōga (pickled ginger), shichimi (ground chili pepper), and a side dish of miso soup. Gyū is the prefix for anything cow-related, and don is short for donburi, the Japanese word for "bowl".
Due to the Movement Towards Westernization (文明開化 - Meiji Restoration in Japan) that Japan experienced in the Meiji Era, western customs like eating beef were adopted and spread throughout Japan.
The prototype for the modern gyūdon as a dish for the general public was invented at this time from gyūmeishi.
Gyūdon is considered to have come from Sukiyaki-don and the old dish gyūnabe, where thin slices of beef are cooked with vegetables in a pot, and at some point was put over rice and served in a bowl.
I saw you in my nightmare, glowing in the dark
Oh baby, baby tiger, I need you back
To hide the nights out of my sight
And when you reached the big tree, your belly reached mine
You tied me up with your feet and with your mouth
You made me come a thousand times (x 2)
And my heart might not be shaped like yours
But I swear it is big enough to be your home
I'm the milk in your cereal bowl
Oh baby, baby tiger, I tame you with my breast
I rub you in the shower, I'll do my best
And I know you're wild but we've got time
And I give you while the best I'll find
And my heart might not be shaped like yours
But I swear it is big enough to be your home
