What are Somen Noodles?
Somen is one of Japan’s most recognizable dried noodles. It is known for its extremely thin, smooth texture. It is primarily made from wheat flour and then dried. Like other Japanese noodle staples—such as Soba and Udon—Somen is a traditional component of the Japanese diet. Because Somen is so thin, it requires very little cooking time. Therefore, it is most often served chilled during the hot season.

The Japanese Custom of Eating Cold Noodles: Why Somen is Eaten in Summer
In many cultures worldwide, noodles are typically consumed in warm soup or with hot sauces. However, in Japan, Somen plays a vital cultural role: a means of coping with the humid heat of summer.
Enjoying Ryō (Coolness) through the Senses
The summer heat in Japan is managed through the cultural concept of Ryō. This concept involves cooling the senses. By thoroughly chilling boiled Somen in cold water and ice, and serving it attractively in glass bowls with ice, the food offers a visual sensation of coolness.
The Purpose of Lowering Body Temperature
Eating cold Somen dipped in cold mentsuyu (noodle sauce) is intended to reduce the body’s heat from the inside. This is one of Japan’s traditional wisdoms for making the hot summer comfortable.
Smooth Texture and Appetite Stimulation
The delicate, smooth texture of Somen makes it easy to eat. This is true even when the summer heat suppresses the appetite. It provides quick energy.
How to Cook Somen Noodles Easy and Delicious (Cold Preparation)
The key to cooking Somen deliciously—similar to preparing Udon or Ramen—is to avoid overcooking and to chill the noodles quickly.

1. Boil Plenty of Water
Bring a large pot of water to a rolling boil. Using insufficient water can cause the noodles to stick together.
2. Cook the Noodles
Add the Somen to the boiling water and cook quickly according to package directions (usually around 1.5 to 2 minutes).
3. Chill Swiftly in Cold Water
Immediately drain the cooked noodles in a colander and vigorously rub them under cold running water until the surface starch (sliminess) is completely washed away. This thorough chilling process maximizes Somen’s characteristic elasticity (Koshi) and smooth texture.
4. Serve the Noodles
Serve the Somen in a bowl with ice water and dip it in mentsuyu (a dipping sauce). Garnish with toppings like green onions or ginger.

A Seasonal Delight: The Culture of Nagashi Somen (Flowing Noodles)
In Japan, a unique custom called Nagashi Somen involves gathering with family and friends. The goal is to catch Somen as it flows down a bamboo chute with water. This is considered not just a meal, but a fun activity. In addition, it helps people forget the heat of summer.
