Udon noodles are boiled in a pot of hot water. Depending on the type of udon, the way it is served is different as well. Udon noodles are usually served chilled in the summer and hot in the winter.

Cold udon, or udon salad, is usually mixed with egg omelette slices, shredded chicken and fresh vegetables, such as cucumber and radish. Toppings of udon soup are chosen to reflect the seasons.

Korea
In Korea, authentic Japanese udon dishes are served in numerous Japanese restaurants, while the Korean-style udon noodle soups are served in bunsikjip (snack bars) and pojangmacha (street stalls). Both types are called udong (우동), which is the transliteration of the Japanese word udon (うどん). In Korea, the word udong refers to noodle dishes (typically noodle soup), while the noodles themselves are called udong-myeon (우동면; "udong noodles") and considered a type of garak-guksu (가락국수; "thick noodles"). Common ingredients for udong noodle soup include crowndaisy greens and eomuk (fish cakes), neither of which are very common in Japanese udon dishes.

Palau
There is a dish called udong in Palau, originated from the former Japanese administration. The broth is soy sauce–based like Japanese udon. However, as there were many immigrants from Okinawa, it uses less broth like Okinawa soba. Most notably, the noodle is that of spaghetti, as it is easier to acquire there.

Languages of the neighboring Federated States of Micronesia also have similar loanwords from Japanese udon; Chuukese: wutong, Pohnpeian: udong, Kosraean: utong, and qudoong.

Philippines
odong or udong of Davao Region and Visayas is inspired by the Japanese udon, although they share no resemblance in modern times. Odong are wheat based yellow thick Chinese noodles (pancit), similar to Okinawa soba. A typical odong bowl is prepared with canned sardine and tomato sauce. Other dishes such as layering with greens are also popular. During the early 1900s, there was a large community of Japanese laborers in Davao, half of them Okinawans. In this period, the Japanese manufactured odong.

Tourism
Kagawa prefecture is well known throughout Japan for its sanuki udon (讃岐うどん). It is promoted to other regions of Japan through themed mascots, souvenirs and movies.
