[ Note ] "The Room to Choose"

Photo by Shinpei Kato

When faced with something whose meaning has been decided down to the last detail, I sometimes feel a slight sense of suffocation.

The maker's intent covers everything in the work, and the viewer is only asked to read it correctly. I can't easily draw close to something that feels that way.

What I’m drawn to instead is something that is clearly formed, yet still leaves room for the person receiving it.

Something complete, yet not closed.

There is a space there that lets the viewer enter while still carrying their own sensibility.

When I think about this idea of “not closing,” what comes to mind is Lee Ufan.

Lee Ufan is the artist who led Mono-ha, the “School of Things” that emerged in Japan in the late 1960s, and the theoretical pillar behind it. In his work, natural stones, iron plates, and glass do not serve as subordinate materials for expressing something; instead, they retain their own existence while forming relationships with one another.

The place where the work is set. Light and air. The distance between one thing and another. And the body of the person who walks through that in-between space and stops. The work does not come to completion within a single object; through encounters with what surrounds it, it creates a different field each time.

The blankness there is not an empty space left for free interpretation, nor is it a part that could not be finished. I think it is an intentionally opened field for things, space, and the viewer to act upon one another.

I can't speak of it in the same way as Lee Ufan's work, but within the idea of “choice” that we have valued, there is also something that can be called “space.”

cobaco has collections such as 『Jewelry with a choice of birthstones』and 『Selectable Gold Rings』where the wearer can choose the type and number of stones, the color of the gold, the ring width, and the finish.

This was not born from the idea that the more options there are, the better.

We shape the form and take responsibility for the quality. On that basis, we do not let the brand decide alone what is right for each person. We do not turn the wearer into the recipient of a story that has already been finished.

Even with the same design, the look changes depending on the stone and materials chosen. The appearance also varies with skin tone, styling, and the way the light falls. If you include the reasons for choosing it and the time that accumulates afterward, no two pieces of jewelry are the same.

People choose jewelry, and jewelry in turn slightly changes their outfit, their movements, and how they feel that day. Within that quiet interaction, meanings and value beyond our imagination are born.

What the maker decides, and what is entrusted to the wearer.
We value what emerges from that in-between in everything we make.

[ New In ] A new ring has arrived in the "Jewelry with a choice of birthstones" collection



A new ring is joining the collection“Jewelry with a choice of birthstones”.

The design “cone,” which was so well received during last year’s holiday season, is now available as a birthstone ring. It was inspired by customer feedback: “I’d love to see a ring with a slightly larger birthstone.”

Among the collection, this ring features the largest birthstone. The refined presence of a single stone shines through. Please take a look as one of the new options.

Daily Note

[ Note ] Up Close, No One Is Normal

The other day, I watched the latest film by director Ryusuke Hamaguchi, A Sick 23-Year-Old.?

The story is set in a care facility in the suburbs of Paris. It centers on the encounter between the facility director, who is searching for a more humane form of care, and a Japanese theater director with stage IV cancer. Through the relationship between the two, it portrays the tension between the ideal of care and labor shortages and economic rationality, as well as how illness, disability, death, and each person's individuality are treated in society.

It felt like a story that had been born in this moment, with a certain inevitability.

Within the more than three-hour film, there are many memorable lines and scenes. Among them was a phrase that, for some reason, stayed in my head even after I finished watching.

“Seen up close, no one is normal.”

It is the title of a play that appears in the story.

When those words appeared in the subtitles, they suddenly seized my heart. They sounded a little blunt, but I felt they captured one truth about human beings.

People who live in the same country. People who work at the same company. People who share the same hobby. Through various attributes and labels, we make a provisional understanding of ourselves and others.

That, too, is necessary for living in a complicated world. We cannot know from scratch the background and circumstances of everyone we meet. By giving people a certain outline, we find our place in society and relate to one another without too much friction.

But as we grow closer to someone, details begin to protrude little by little from that rough outline.

Odd fixations. Incomprehensible habits. Anger and sadness that only the person themselves can understand. The closer we get, the more the person’s unique distortions, invisible from afar, inevitably come into view.

Writing “distortions” may sound negative in some way. But it is also something that could be called “individuality.” And of course, the one who is distorted is not only the other person.

We can only see others through the lens of our own experiences and values. Even when we think we understand someone, what is there is still only “the person as seen through my eyes.”

When people with different distortions look at one another from different angles, it makes the idea of fully understanding each other seem stranger, in a way.

Perhaps we have created shared standards such as “normal,” “common sense,” and “sane” in order to live together while carrying that incomprehensibility. That, too, is one kind of wisdom for people who are “individualistic” to live in the same place.

But if we demand those standards too strongly, people who fall outside them will emerge. Some may even be forcing down their own contours just to remain inside the group. In the first place, being inside a group and being “normal” are not the same thing.

Recognizing one another's differences does not mean understanding everything about the other person, nor does it mean accepting everything. Sometimes it is necessary to draw boundaries.

Even so, we should not immediately treat the parts we cannot understand as mistakes or defects. Leave what we do not understand as it is, without forcing an explanation.

That seems like the only place to begin.

Seen up close, no one is normal.

That is why, rather than measuring whether the person in front of you is “normal,” we should focus on what kind of unique outline that person has.

To treat someone as a human being is not to understand them completely, but to leave room for what cannot be understood while not stripping away their uniqueness.

To live in the same world while carrying different outlines. In that difficulty, there may also be the richness of relating to other people.

[ Note ] Sound of Premonition

As I headed toward my destination and walked straight down the street,
I noticed shide streamers and lanterns hanging from the eaves.

All around town were people wearing happi coats.
Farther ahead, I could even see a mikoshi that was still in the middle of being assembled.
It looked like a festival was about to begin.

Near the corner just beyond that,
I could hear the rhythm of drums leading the way.

They were probably practicing for the main event.
In contrast to the blazing summer sun,
a breeze typical of early summer was blowing through the street,
and the repeated drumbeats somehow sounded pleasantly soothing.

I stopped hurrying and listened quietly for a while.

Come to think of it, I’ve always had a strange fondness for the sound of practice.

After school, the blended sound of brass instruments from the wind ensemble drifting out of a distant classroom.
The tone of a saxophone in a nighttime park, playing the same phrase again and again.
The sounds of voices warming up and instruments being tuned, leaking from beyond the stage wings.

All of them are a little different from the sound of a fully finished performance.

Sounds that are not yet fully in place, sounds before they take shape.
Sounds that contain not only “right here, right now,” but also “what’s to come.”
There is something in that incompleteness that opens my heart.

The promise of beautiful days.

That phrase suddenly crossed my mind.
It’s the phrase we hold dear.

Beauty does not exist only in a finished form; it is already there in the signs that have not yet been named, and in the shape before it becomes a shape.

And the feeling that something awaits just ahead.
Perhaps we are more supported than we realize by those small signs.

With the sound of the drums fading into the distance behind me, I quickened my pace toward my destination.

Thoughts at the End of Life

"My heart is at peace."

These were the words left by aesthetician Kim Jin-young just before his death.
When I read that one sentence, printed so it stretched across the page, I couldn’t close the book for a while.

To be at peace. It sounds simple, yet it is very difficult. Even more so in times like these.

As we live our days, our hearts are constantly tossed about. Hope and anxiety, anger, impatience, regret. We struggle to keep our balance while being pulled by emotions we can’t fully control. That is why I was so strongly struck by how one might reach a state of mind at the end of life where one can say, “I am at peace.”

Kim Jin-young’s posthumous collection Morning Piano is a diary that traces the days from when he was diagnosed with cancer until his death.

It does not record only quiet acceptance. Confusion and sorrow, anger, an inability to let go. The emotions sway back and forth again and again, and each time they are written down as words.

And yet, as I kept reading, gradual change began to appear.
What started as long passages gradually became shorter. The style, which had felt essay-like, soon turned into fragments, and in the end only words like a few lines of poetry remained.

As if all the excess were being quietly pared away. As if the soul were quietly leaving the body. The words grew shorter little by little, losing their outlines as they sank deeper and deeper. That process was beautiful.

Perhaps people do not simply end all at once in a single moment. While remaining in the body, they slowly drift away. Their outlines gently unravel. Morning Piano recorded that quiet transition.

After closing the book, I found myself thinking.
At the end of life, what will I think about?

I don’t know the answer. But strangely enough, I thought that maybe it is unexpectedly the scenery of the present.

Casual conversations with family. The evening light streaming in through the studio window. The quiet breathing of a cat dozing on the living room sofa. A table with steam rising from it. The small days that slip by unnoticed amid the busyness.

Perhaps those are the things that, later on, we look back on and think, “Ah, that was enough.” Or perhaps we simply hope that we will be able to feel that way.

I still don’t know when that day will come. But I do find myself looking forward to it a little.

[ New in ] New Collection “Node” Debuts

Starting today, Friday, May 22, the new “Node” collection has launched, featuring hexagonal natural stones held in place by just two prongs.

This collection focuses on “nodes” (= Node), where forces gather and form takes shape. The natural stones are supported with a structure pared down to the bare minimum.

A quietly balanced beauty of form that emerges when all unnecessary structure is stripped away.
You can fully appreciate the unique colors and patterns of each opaque stone.

In addition to the collection page, we’ve also published a column focusing on the craftsmanship behind “Node,” as well as a column compiling coordination samples. Please take a look.

[ Note ] My Own Sensitivity at Least

"Protect your own sensitivity yourself, you fool."

These are the words of the poet Noriko Ibaragi.
Lately, this line has started to come to mind at unexpected moments.

In daily life, I find myself, without noticing, drifting toward the side that is being "asked of."Meeting expectations.That in itself is an essential attitude in work. But in the process,the outline of who I am becomes slightly blurred.There are certainly moments when I feel that sense of unease.

While responding to what is asked of me,how much of my own sense is actually involved? To what extent can I take that action,as truly my own? These days,I have become more conscious of that.

For example, the "personality" others see in me.They probably think I listen to this kind of music, or live this kind of life.I feel I no longer hesitate as muchto step a little outside those images as I once did. That does not meanI am dismissing other people's expectations; it means pulling my own sense of thingsback to my side, at least for a moment.

I can only receive the world through this body.I cannot borrow someone else's sensitivity,and I cannot have someone else feel in my place. That is why,however incomplete it may be, I want to remain honest with my own senses.

Protect your own sensitivity.
First, acknowledge it for yourself.

After all these years,I have finally come to feel that way.

[ New in ] Atelier Coat Resale Notice



Last autumn, our original atelier coat sold out of stock immediately after it went on sale. After that, the fabric we used was discontinued, and we sadly had to end sales.

This time, thanks to the kindness of the daily wear brand "FRANCESCA AMAM LABEL," which we asked to produce it, they made just1 piece using the fabric that was left on hand. We also actually wear it as workwear, but it has a refined feel within its relaxed shape, and it's a piece that makes you straighten up every time you put it on.

This week2月27 (Fri) starts at 8 PM. Limited to1 piece. If you'd like one, please order early.

[ Note ] From One Small Choice

"If the cravat knot isn't perfect, the outfit isn't complete."


Beau Brummell, who lived in Regency-era Britain in the late 18th to early 19th century, is known as the original dandy and as the man who transformed the values of men’s fashion at the time.

At a time when lavish attire adorned with jewels and embroidery was the norm, he presented a thoroughly pared-down aesthetic: a plain dark suit, a crisp white shirt, and a perfectly tied cravat (the precursor to the necktie).

It is said that he would stand in front of the mirror for hours retieing his cravat, and if he was not satisfied, he would change his entire outfit. What lay behind it was not vanity, but the belief that "a single discord can throw off the whole."

To carry your philosophy through to even the way you tie your necktie.
It is also a question of how to shape your own existence.

One small choice changes you, if only a little.
The changed me chooses something else again.
Within that chain, a distinctive character takes shape.

I think the same is true for brands as well.

One design, one material, one word.At the same time that this accumulation shapes what makes it distinctive, it also renews the brand itself.

This year, cobaco is 17We have reached our anniversary year.
Looking back, I find myself in a very different place from what I had originally envisioned. But that change was by no means a break; it lay along the extension of countless small choices.

If I may borrow Brummell's words,Paying attention to the details may also be a way of shaping the future.

What will cobaco look like by the time it celebrates its 20th anniversary?You may find yourself standing in a place we can't even imagine right now.

A brand is not a fixed logo, but something that grows and evolves as it breathes.
I hope to continue quietly enjoying that change.

From Wednesday, March 4 to Tuesday, March 10, we will hold a pop-up shop at Osaka's Hanshin Umeda Main Store. This one-week event is a chance to experience the true texture and quiet presence of cobaco jewelry in person. We look forward to welcoming everyone in the Kansai area and nearby regions.

[ Hanshin Umeda Main Store Special Event Exhibition ]
Seasonal limited collection "Jewelry with a choice of birthstones"

At this event, we will specially exhibit and sell the limited collection "Jewelry with a choice of birthstones," which is normally available only from November to December.

From the rose cut, which originated in the 16th century,
to the round brilliant cut, the modern standard.
We selected four different cuts, tracing the history of diamond polishing.
This collection is created as a combination jewelry piece
that brings together K18 yellow gold and platinum.

The way light reflects, the structure of the facets, the quality of the brilliance—
please compare how each cut creates a different expression.

New items from the "Staple" collection also debut

The "Staple" collection applies the structure of a construction hardware staple (kasugai) to stone setting. This collection will feature long earrings with round natural stones, a first for the line. Other shapes, including items not yet listed online, will also be available at the venue. Earrings and select rings can be purchased on the spot, so you can take them home right away.

Novelty gift

Customers who spend 30,000 yen or more, tax included, will receive a brand-original jewelry tray as a gift for the first 20 people. (*Offer ends once supplies run out.)

Other offerings
• Display of staple items including the "Jewelry with a choice of birthstones" collection

Daily Note

[ Note ] Beauty Resides in Intelligence

At the end of last year, I was chatting with a graphic designer I often work with at the atelier, combining a meeting with casual conversation.

While looking back over the year, our talk shifted from work to everyday life, and the word "imagination" suddenly came to the surface. After all, when people interact, isn't imagination the most important thing? Our thoughts naturally aligned around that idea. There are many ways to define it, but in our conversation that day we agreed that imagination might be "the ability to attend to another person's feelings."

That said, it's by no means easy. After all, "I" am not "someone else." Whether family or friends, there's no way to know exactly what someone else is thinking. No matter how much knowledge or experience you accumulate, that alone doesn't let you reach another person's feelings.

The other day, I was talking with a friend at a café. I glanced at my friend's hands and saw their glass was nearly empty. Just as I was about to call the server, someone quietly poured more water and said, "I'll refill that for you."

It wasn't a dramatic gesture. They observed the person's condition, read a small sign, and chose an action that was neither too much nor too little. It felt less like "kindness" and more like a quiet, intelligent process. From that small consideration there was a hint of beauty.

The accumulation of attitudes directed toward others becomes intelligence, which eventually takes on grace and quietly seeps outward. As we imagine how what we create sits beside someone, we will continue devoting ourselves to jewelry making this year.
