A Shimane Tour Beyond Sightseeing: Traditional Soy Sauce in Okuizumo

Where Time Becomes Flavor

When people search for a Shimane tour, they often begin with well-known places such as Izumo Taisha, Matsue Castle, or the Adachi Museum of Art.

But deeper in the mountains of Shimane, places like Okuizumo offer another way to understand the region.

Here, travel is not only about what you see.

It is about meeting the people who continue to shape the culture of the place.

One of those people is Ikufumi Morita, the 10th-generation brewer of Morita Soy Sauce.

In Okuizumo, soy sauce is not rushed.

It is allowed to age, change, deepen, and settle.

Surrounded by mountains and clear water, Morita Soy Sauce continues to make shoyu through a process that depends on patience rather than speed.

When mass-produced soy sauce became cheaper and more widely available, the answer here was not to compete on price.

Instead, Morita asked a different question:

What would I feel safe giving my own children for the rest of their lives?

That question became part of the philosophy behind the brewery.

Traditional Shoyu in Rural Shimane

Inside the brewery, large wooden barrels stand quietly.

They are bound with hand-braided bamboo hoops and used for the slow fermentation of soy sauce.

These are not simply objects from the past.

They are still part of the living process.

Some soy sauces are aged for three years.

Some are brewed again using soy sauce itself instead of salt water.

Others remain raw and unpasteurized, keeping a softer aroma and a different character.

Here, time is not something to overcome.

It is something to trust.

A Different Kind of Shimane Experience

Many visitors arrive thinking they already know soy sauce.

For them, shoyu may simply be something on the table.

Something used with sushi.

Something familiar.

But once they step inside the brewery, smell the fermentation, see the wooden barrels, and hear the story directly from the maker, their understanding begins to change.

Then comes the tasting.

Different depth.

Different aroma.

Different texture.

And sometimes, after tasting one of the longer-aged soy sauces, there is a pause.

A surprised expression.

Then something very simple:

“Oh my God. This is so good.”

That moment is important.

Because it is no longer only about taste.

It becomes a moment of realization.

Understanding the Thinking Behind the Flavor

Alongside the brewer, a local Storyteller helps guests understand the background.

Not simply translating words, but offering context.

Why does one soy sauce feel rounder than another?

Why does the salt not arrive first?

Why does the water of Okuizumo matter?

Why continue making soy sauce this way when faster methods exist?

Once you begin asking these questions, soy sauce stops being only a condiment.

It becomes a reflection of place.

Of food.

Of water.

Of climate.

Of responsibility.

Of the choices people continue to make.

Craftsmanship as a Way of Thinking

What makes a visit to Morita Soy Sauce meaningful is not only the product itself.

It is also the thinking behind it.

There is a sense of responsibility to the ingredients.

To the people who will eat it.

To the next generation.

And to the knowledge that has been carried forward.

For us, this is one of the deeper ways to experience rural Japan.

Not by simply seeing something traditional.

But by understanding why people continue to protect it.

From Visitor to Understanding

This is why we share Morita Soy Sauce through ThoughINAKA.

A visit here can become part of a private journey through Okuizumo and rural Shimane, connecting food, craftsmanship, landscape, and the people behind them.

We do not want guests to leave simply saying:

“I tasted good soy sauce.”

We hope they leave thinking:

“Now I know.”

Now I know what real shoyu can taste like.

Now I know how much time and thought can exist inside something so ordinary.

Now I understand a little more about how people in rural Japan think about food, craftsmanship, and responsibility.

That kind of understanding stays with you.
