Standard broth differs by region. Dark (koikuchi) soy sauce is added in eastern Japan, while light (usukuchi) soy sauce is added in the west. Instant noodles are often sold in two (or more) versions accordingly.

More unusual variants include stir-fried yaki udon and curry udon made with Japanese curry. Udon is often used as the final dish in shabu shabu or Japanese hot pot.

Dishes

Udon noodles are cooked before eating, usually by boiling in water. Different types of udon are produced to suit different ways of serving them. Udon noodles are usually served chilled in the summer and hot in the winter. In the Edo period, only the thicker wheat noodle was generally called udon, and was served with a hot broth called nurumugi (温麦). The thinner variety, served chilled, was called hiyamugi (冷麦).

For cold udon, or udon salad, the noodles are usually mixed with usuyaki-tamago, shredded chicken, and fresh vegetables such as cucumber and radish. Toppings of udon soup are chosen to reflect the seasons. Most of the soup toppings are added without cooking them much, although deep-fried tempura is sometimes added. In many of these dishes, udon noodles can be replaced with soba.

The term nanban is a reference to the Nanban trade which influenced Japanese culture for a century until it was banned in 1639 by the Edo Shogunate. Biei, Hokkaido is famous for a unique curry udon.

Yakiudon is relatively simple to make and a popular staple of Japan's izakaya, or pubs, as a late-night snack.Originated in Kitakyushu, Fukuoka Prefecture. The widely accepted story of how the dish was created dates back to just after World War II, when food was scarce. The owner of the noodle restaurant Darumado used udon noodles in popular yakisoba preparations, because the proper noodles were not available.
