Traditional Shodoshima Somen Noodle
ONE OF JAPAN’S THREE GREAT SOMEN Noodle TRADITIONS
Over 400 Years of Hand-Stretched Craft
Somen is one of Japan’s traditional wheat noodles — exceptionally fine, delicate strands most famously enjoyed chilled during the hot summer months.
Cooked only briefly, then rinsed and chilled in cold water, somen is traditionally enjoyed with a light tsuyu dipping sauce and simple seasonal condiments such as ginger and green onion.
Its cool, clean and delicate character has made somen a familiar part of Japanese summer food culture for generations.
Among Japan’s celebrated somen traditions, Shodoshima is recognized as one of the country’s three major somen-producing regions, alongside Miwa in Nara and the Banshu region of Hyogo, home of Ibonoito.
Shodoshima has preserved its tradition of te-nobe — hand-stretched somen — for more than 400 years.
Among the names that represent this heritage is Shima no Hikari, produced by the Shodoshima Hand-Stretched Somen Cooperative. The cooperative itself describes Shodoshima as one of Japan’s three major somen-producing regions and identifies sun-drying, sesame oil and repeated maturation as defining elements of Shima no Hikari.
Yet what makes Shodoshima somen special is not simply its age.
The island itself has shaped the tradition.
SHAPED BY THE ISLAND
Sun, Wind & the Seto Inland Sea
Shodoshima lies in Japan’s Seto Inland Sea, where the island’s natural environment and agricultural life helped create the conditions for somen making.
The tradition is believed to have begun around 400 years ago, when the technique of somen making was brought back to Shodoshima from Miwa in Nara.
It was particularly well suited to island life: somen could be produced during the quiet winter agricultural season and traditionally developed as a family-based craft.
Winter became an important part of this rhythm.
After being carefully stretched into extraordinarily fine strands, the noodles were dried outdoors, exposed to the clear air of the Seto Inland Sea.
Even today, Shima no Hikari continues the tradition of sun-drying, at a time when indoor drying has become increasingly common elsewhere.
Rows of brilliant white somen hanging beneath the winter sky are therefore more than a picturesque scene.
They are part of Shodoshima’s living food culture.
WHAT MAKES SHODOSHIMA DIFFERENT
Sesame Oil — a Signature of the Island
One of the most distinctive characteristics of Shodoshima somen is something unusual:
sesame oil.
During the hand-stretching process, a small amount of oil is applied to prevent the increasingly delicate strands from sticking together as they are gradually drawn thinner and thinner.
While cottonseed oil is used in some other somen-producing regions, Shima no Hikari traditionally uses specially prepared sesame oil. According to the cooperative, sesame oil is less susceptible to oxidation and helps protect the quality of the finished noodles.
This practice also connects somen with another craft deeply associated with Shodoshima — its long-established sesame-oil culture.
Together with carefully selected wheat flour and salt from the Seto Inland Sea, sesame oil, maturation and sun-drying create the distinctive character of Shima no Hikari:
fine and delicate, yet remarkably firm, smooth and resilient.
THE ART OF TE-NOBE
Not Cut — Stretched
The secret of traditional somen lies in the words te-nobe — “hand-stretched.”
This is fundamentally different from simply cutting dough into increasingly thin noodles.
The dough is formed into strands and progressively stretched. Between stages, it is allowed to rest and mature before being stretched again.
Stretch. Rest. Mature. Stretch again.
Little by little, the strands become remarkably fine while retaining their structure.
Japan’s official JAS standard for te-nobe dried noodles reflects this distinction: the process requires noodles to be progressively stretched, with designated hand-worked stages and periods of maturation rather than simply being mechanically cut into shape.
Time is therefore as important as the hands of the maker.
This patient process creates one of the qualities prized in fine Japanese somen:
koshi — a satisfying firmness and resilience that seems almost surprising in a noodle so delicate.
Shima no Hikari is particularly known for this combination of strong koshi and a remarkably smooth mouthfeel.
A LIVING CRAFT
Tradition That Cannot Simply Be Rushed
Hand-stretched somen is still produced in several historic regions across Japan, so te-nobe itself should not be described as a disappearing rarity.
What is increasingly valuable, however, is the continuation of the knowledge, time and specialist techniques required to make it properly.
Traditional te-nobe production involves a long sequence of forming, resting, maturing and stretching. Some stages may use equipment today, but the defining hand-stretched processes and maturation distinguish it fundamentally from ordinary machine-made dried noodles.
On Shodoshima, this knowledge has traditionally been carried through generations of producers, often rooted in family-based winter production.
Today, the makers behind Shima no Hikari continue to preserve the island’s 400-year tradition of hand-stretching, repeated maturation, sesame oil and sun-drying.
This is not simply an old technique remembered from the past.
It is a tradition still being practiced today.
SOMEN IN JAPANESE CULTURE
The Taste of Japanese Summer
For many Japanese people, somen immediately evokes summer.
The noodles require only a short cooking time before being rinsed thoroughly and chilled in cold water.
They are commonly served simply, accompanied by a light tsuyu dipping sauce and condiments such as ginger, green onion or myoga.
The experience is deliberately uncomplicated:
cool, light, refreshing and delicate.
This simplicity is part of its appeal.
Rather than overwhelming the noodle with a heavy sauce, the clean dipping broth allows its texture and subtle wheat character to remain at the center of the meal.
Somen is not limited to summer, however. During cooler seasons it can also be served warm in broth as nyumen, giving the same delicate noodles an entirely different character.
In this way, somen is more than simply another type of Japanese noodle.
It is closely connected with Japan’s sense of season and the way food changes with the time of year.
A TASTE OF SHODOSHIMA
An Island Where Food Traditions Meet
Shodoshima’s somen did not develop in isolation.
Across generations, this small island in the Seto Inland Sea became home to distinctive traditions of soy sauce, sesame oil and hand-stretched somen.
Each has its own history, yet together they tell a larger story about Shodoshima.
Its landscape and climate shaped how food could be produced. Winter provided a natural season for somen making. Salt from the Seto Inland Sea became one of its essential ingredients. Sesame oil became part of the stretching process. Sun and air became part of its drying tradition.
And generations of local makers transformed these conditions into knowledge that has endured for more than four centuries.
Today, Shima no Hikari carries that tradition forward.
What appears at first to be a simple bundle of extraordinarily fine white noodles is therefore something much deeper:
an island, its climate, its ingredients, its people — and more than 400 years of accumulated craftsmanship.
Fine strands. Remarkable resilience.
A tradition shaped by Shodoshima.
