FUNDAMENTALS

What is Juwari Soba?

Buckwheat flour alone, no binder — it hides nothing.

01

The meaning of "Juwari"

Most soba is "nihachi" — 80% buckwheat, 20% wheat. Juwari is 100% buckwheat. Without a binder it is far harder to make, so the maker's skill becomes the flavor itself.

02

Aroma & texture

With no wheat, the wild fragrance of buckwheat stands out. Delicate strands that break easily — freshly milled, cut and boiled is everything.

03

The connoisseur's way

First a bite plain, for the aroma. Then a touch of salt, then a little sauce. Finish by diluting the sauce with sobayu — the hot cooking water — so nothing is wasted.

HISTORY & TRADITION

Nine thousand years of memory

Since the Jōmon era, soba has lived alongside life in Japan. A walk through its history.

Jōmon

Jōmon period — earliest traces

Buckwheat traces appear at Neolithic sites of 4000–2000 BCE, showing how ancient soba's presence in Japan is.

722

An imperial edict

Empress Genshō issues an edict urging buckwheat cultivation against drought and famine — a crop that grows in poor soil.

1574

First record of soba-kiri

A record at Jōshō-ji temple notes soba-kiri served to temple workers — the oldest written mention of soba as noodles.

Edo

Edo — soba flourishes

Soba shops bloom across Edo — at yatai stalls and as year-crossing toshikoshi soba. Rich in thiamine, it even guarded against beriberi.

Now

Today — return to juwari

Juwari specialists devoted to house-milling and stone-grinding rise nationwide — now drawing the world's eye as gluten-free cuisine.

HEALTH & NUTRITION

A bowl that's good for you

Gluten-free and richly nourishing — here are the health benefits of pure-buckwheat soba, one by one.

GLUTEN FREE

No wheat.
Nourishment of the "meat of the field."

Juwari soba uses no wheat — it is naturally gluten-free. Buckwheat is so nutritious it is called the "meat of the field," a bowl worth bringing into everyday meals.

Most notable is buckwheat's signature polyphenol, rutin — and studies suggest juwari holds more of it than nihachi soba.

01

Gluten-free

Naturally free of wheat and gluten — easy to enjoy for those mindful of wheat, with a light finish.

02

Rutin (polyphenol)

Buckwheat's signature polyphenol. Said to strengthen capillaries and act as an antioxidant, helping guard against high blood pressure and arteriosclerosis.

03

Dietary fiber

Soba carries more fiber than white rice or udon, supporting gut health and easing sharp rises in blood sugar.

04

Quality protein

A complete protein with all nine essential amino acids, supplying the lysine that rice and wheat tend to lack.

05

B vitamins

Rich in B1 and B2, aiding the metabolism of carbohydrates and fats. In Edo, soba even helped guard against beriberi.

06

Low-GI & satisfying

A low-GI food that raises blood sugar gently. Filling and satisfying — a fine staple even while watching your diet.

Finish with "sobayu" — waste no nutrient

Much of soba's goodness — rutin, B vitamins, protein — is water-soluble and dissolves into the cooking water. That is why finishing by diluting your tsuyu with sobayu makes such good sense. Warming to the body, it has long been valued, even as a guard against hangovers.
