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.

GLUTEN FREE

No wheat. A bowl that's good for you.

Juwari soba uses no wheat — naturally gluten-free. Buckwheat is rich in rutin, a polyphenol said to strengthen blood vessels and act as an antioxidant, and studies suggest juwari holds more of it than nihachi.

It contains all nine essential amino acids, complementing what rice and wheat lack — plus fiber, B vitamins and minerals, low-GI and satisfying.
