Many foreigners do not have the habit of eating rice and side dishes separately and mixing them in the mouth. Therefore, if the side dishes and rice are separated like in a Japanese set meal ”TEISYOKU”, they cannot mix them to the right taste in their mouths, so they cannot enjoy or are not good at it. Therefore, foreigners, especially Westerners, prefer to eat a bowl of rice mixed with side dishes from the beginning, They prefer katsudon to tonkatsu set menus "Tonkatsu TEISYOKU", and Gyudon, Tendon, and Oyakodon are more preferable than their respective set menus served separately"TEISYOKU", Sushi is also easy to eat because it starts with a portion of rice and a fish fillet. Onigiri is also a favorite of foreigners because the ingredients are wrapped in white rice and can be eaten in one bite, so there is no need to adjust the taste by mixing them in the mouth. Most of the examples here are served in the same way, Omelette Rice, Takikomi-Gohan, and Dry Curry are all actually the same in that they are all eaten without independent white rice. The way of eating that mixes and neutralizes the flavors of side dishes in the mouth with white rice is actually a way of eating unique to the Japanese.
