SHIZQ Tsuru Rock Glass Pair Set

The SHIZQ “Tsuru” Series brings out the natural color and grain of Kamiyama cedar itself.

The reddish heartwood near the center of the tree and the pale sapwood surrounding it create natural variations in color. These differences within a single tree form a beautiful two-tone expression unique to each vessel.

To the touch, cedar has a characteristically soft texture. When it catches the light, the grain and growth rings take on a gentle, silk-like sheen.

To preserve as much of cedar’s natural character as possible, the surface is finished with a special clear coating. Made with materials suitable for everyday use, it helps protect the wood from moisture, stains, and ultraviolet light.

The vessels can be used not only for coffee and tea, but also for foods containing oils.

Even for those who feel that wooden tableware might be difficult to care for, we wanted these pieces to be used freely and comfortably at the everyday table. The Tsuru Series is designed to preserve the natural beauty of cedar while remaining practical for daily life.

The natural red and white tones created by cedar’s heartwood and sapwood. The growth rings that mark each passing year over decades of growth.

The Tsuru Series carries both a sense of celebration, well suited to special occasions, and the story of a tree shaped by time.

For weddings, new homes and moves, career transitions and retirements, wedding anniversaries, longevity celebrations, and many other milestones in life.

Its clean, understated form, shaped by the natural growth rings of cedar, fits comfortably into a wide range of lifestyles, regardless of age or gender.

No two pieces share the same grain or growth rings. That means every cup, bowl, or plate you give has an expression all its own.

After spending many years growing in the mountains, the cedar begins a new chapter, sharing time with someone important in their everyday life.

The ability to give not only a vessel, but also this sense of time and continuity, is one of the reasons the Tsuru Series has long been chosen as a meaningful gift.

Just as no two trees are exactly alike, no two SHIZQ vessels share the same expression.

The shades and spacing of the growth rings, the balance of heartwood and sapwood, and the movement of the grain all reflect the time and environment in which each cedar tree grew over many years.

Periods of slower growth and periods of vigorous growth accumulate differently in every tree, which is why the width of the growth rings and the character of the grain are never exactly the same.

Dark tones or blurred-looking patterns may also appear on the surface of the wood. Some of these come from resin produced by the cedar itself to protect against moisture, injury, and other stresses.

These are not stains or artificially added patterns, but natural traces of the life the tree has lived.

As you look at the growth rings, you might find yourself wondering, “What kind of place did this tree grow in, and what kind of time did it experience?” That sense of imagination is also part of the pleasure of owning a SHIZQ vessel.

We embrace the grain, color, and even the expressions created by resin as part of the unique character of each tree.

We hope you will look forward to discovering the one-of-a-kind vessel that arrives in your hands.

In Kamiyama, Tokushima, the amount of water flowing through the rivers has decreased by approximately 30% compared with 30 years ago.

The Kamiyama Shizuku Project began with the aim of restoring the water-retaining capacity of the mountains by caring for overcrowded cedar plantations and making meaningful use of the trees that are removed.

Caring for the forest also means using the harvested timber responsibly and connecting it to new forms of value.

SHIZQ transforms Kamiyama cedar into objects people will want to use and cherish for years, creating a new connection between the forest and everyday life.

Using a SHIZQ product—or giving one to someone important—is also a small action that brings attention to the forests of Kamiyama and supports this ongoing effort.

From using a single cedar tree, back to the forest.
From the forest, to the water.
And from the water, to the children who will inherit the future.

So that we can leave as many “shizuku”—drops of water—as possible for generations to come.

We hope that each small effort we make will become a single drop, and that those drops will one day spread outward in ever-widening ripples.
