More about Ohmi Ceramics

The Story of Ohmi Ceramics

Founded in Kusatsu, Shiga Prefecture, in 1985, Ohmi Ceramics was established by Yoshinori Yamamoto to restore Kusatsu-yaki, a regional pottery tradition that had nearly disappeared.
Today, he works alongside his son Kazuma, carrying the workshop into its second generation.

Their collection brings this local ceramic heritage into contemporary daily life. Flower frogs, bowls, cups and serving vessels are shaped with restrained forms and a strong sense of function. Rather than reproducing objects from the past, the Yamamotos create pieces designed to be used, handled and lived with.

Each work connects the history of Kusatsu ware with the needs of the modern table, preserving a regional craft through objects that remain practical, tactile and quietly distinctive.

The Roots

The Story of Ohmi Ceramics

The Craft

Clay, Mud and Slow Fire

The distinctive black surface of Ohmi Ceramics is created through material and controlled firing rather than a conventional glaze. Before entering the kiln, each vessel is coated with mineral-rich mud gathered near Lake Biwa.
At approximately 1,100°C, the surface melts and transforms, producing subtle variations in tone, texture and sheen.

Because clay, coating and fire respond differently each time, no two pieces are exactly alike. Gentle asymmetry, firing marks and small changes in the finish are preserved as part of the character of handmade Kusatsu ware.

From chawanmushi bowls and espresso cups to Japanese tea ware and ikebana vases, every form balances tactile depth with practical use.
The result is pottery shaped not only by the maker’s hand, but also by the natural behavior of local materials in the kiln.

The Artisans Behind Ohmi Ceramics

Yoshinori Yamamoto

For more than four decades, Yoshinori Yamamoto has worked to preserve the ceramic heritage of Kusatsu, Shiga.
He established Ohmi Ceramics in 1985, later receiving its official name in 1997, and began shaping local clay through methods influenced by ancient Sue ware and nearby Shigaraki traditions.

A licensed master potter, Yoshinori is known for an understated approach that lets the material speak for itself.
His vessels are fired slowly without conventional glaze, producing the characteristic matte-black surface associated with Kusatsu ware.

Today, he shares the workshop with his son Kazuma, ensuring this distinctive local craft continues into the next generation.

Kazuma Yamamoto

At the Ohmi Ceramics Research Institute in Kusatsu, Kazuma Yamamoto carries forward the work begun by his father, Yoshinori. Together, they have helped restore Kusatsu-yaki, a regional ceramic tradition that had almost vanished from the area.

Inspired by the techniques and earthy character of ancient Sue ware, Kazuma creates pottery with deep black tones and richly textured surfaces. Instead of applying a standard glaze, he coats the clay with mineral-rich mud collected near Lake Biwa.
This material melts at approximately 1,100°C, allowing the pieces to develop their distinctive finish at a lower temperature than conventional stoneware.

Through careful firing and continual experimentation, Kazuma is preserving and developing a craft rooted in the landscape of Shiga.

Between Lake Biwa and Shigaraki

Ohmi Ceramics is based in Kusatsu, Shiga Prefecture, a city set near Lake Biwa and close to the historic pottery region of Shigaraki.
Here, Yoshinori and Kazuma Yamamoto work within a landscape where clay and fire have shaped ceramic traditions for more than a thousand years.

This setting is central to their work. Local materials, the legacy of ancient Sue ware and the influence of nearby Shigaraki guide every piece, connecting contemporary Kusatsu-yaki to the history and natural character of the region.

A note from Tsukushi

How we work with Ohmi Ceramics

We visit the kiln in person.
There are no intermediaries, no agents — every piece is chosen directly from the hands that made it.

In Japan, an artisan places their name and their work in someone else's care.
We take that responsibility seriously.

"A small artisan working in a family kiln produces pieces of extraordinary quality but in limited quantities. We do not see this as a constraint — we see it as a strength."
— Tsukushi

The Shape of Patience

Refined by hand and fire, this Japanese ceramics collection finds its voice in every form: a ceramic coffee cup, a black ceramic bowl, or unique handmade Chawanmushi Bowl.

More than an order, a beautiful memory

We couldn't be happier with our experience with Tsukushi.

We chose a beautiful set of Japanese ceramics to celebrate our third anniversary — our first anniversary in the new home we bought together. Because the date was very important to us, we contacted the shop asking if there was any possibility of shipping our order quickly enough for it to arrive in time.

What happened went far beyond our expectations.

They shipped our order immediately, and the package arrived on the exact day of our anniversary. But the most touching surprise was inside.

We had asked if they could include a little anniversary wish, and they went much further: they included a beautiful handwritten message in Japanese, with a traditional wish for us.

It was an incredibly thoughtful and personal gesture. Opening that package together, on our anniversary, in the first home we have bought together, and discovering their handwritten message turned an already meaningful gift into a memory that will stay with us for a very long time.

The ceramics themselves are beautiful, but what impressed us just as much was the extraordinary care, kindness and attention shown by Tsukushi. You can really feel that there are people behind this shop who understand and care about the meaning that these objects and Japanese traditions can have for the people receiving them.

To everyone at Tsukushi: thank you from both of us. Thank you for listening to our request, for making every effort to get our gift to us in time, and especially for the beautiful handwritten Japanese wish.

You didn't simply deliver our order on time. You became a small but very special part of the memory of our third anniversary and of the beginning of our life together in our new home.

We will think of this experience every time we use our ceramics.

With all our gratitude,

Dear Mr. Amanti,
What a beautiful date to have been part of. Thank you for trusting us with something so personal, and for these words.

With our warmest wishes,
The Tsukushi Team
