Sangenjaya Engraving Studio, established in 1970, proposes a way to seal "a story of two people" in a ring.
The "inside" of the ring is the world's smallest love letter
When choosing a wedding band, the "inner engraving" is as important as the design and material. Invisible from the outside, it is a secret message known only to you and your partner, a proof of your vows that will not fade away even decades later.
Since its establishment in 1970, MITUBACI, an engraving studio in Sangenjaya, has engraved the "feelings" of countless couples. The other day, when a customer who had a ring made 12 years ago came to have it resized, he looked at the engraving from that time and smiled, saying, "I remember how I felt back then. In this issue, we would like to introduce some "engraving ideas you won't regret" with the latest trends, from a craftsman's point of view.
What to engrave? [Message and content section
For two people who want to keep it simple, we recommend the partner's initials and ♡.
For minimalist couples who want to keep the inside clean and clutter-free, the engraving of each other's initials is a firm favorite.
Engrave the initials of your beloved partner on your ring.
The MITUBACI can be engraved with a cute heart mark or cherry blossoms, so we recommend adding them as accents along with the initials.
When in doubt, here it is. The most popular "anniversary date" and a craftsman's secret recommendation for the western calendar (year).
The most popular choice for engraving is the date of the couple's "special day.
2026.11.22 / Nov 22.2026
The day you joined the registry, the day of the wedding, or that special day when you two met. Every time you look at the ring, you will remember the fresh feelings and commitment of that day.
Here, a craftsman who has looked after many customers over the years would like to personally recommend the following,Be sure to include the year.It is. We don't forget the "month and day" of our wedding anniversary because we celebrate it every year, but after a few years or a decade or so, we wonder, "Hey, what year was this that we got married?" What year was it when we joined the registry? It is surprisingly easy to lose track.
At such times, if "2026" is engraved on the inside of the ring, they can always check how far they have come. The other day, a customer who came in for maintenance looked at the engraved date and said, "It's been 12 years already.
The Western calendar is the most reliable record that can tell us the "starting point" of your history.
A collection of phrases from "Latin-English
We have collected sayings to pledge an enduring love that will not fade over time. Latin, in particular, is a prestigious and symbolic choice for "eternity," a favorite in European jewelry culture.
- [Latin: eternal vow]
Ab imo pectore(From the bottom of my heart)Amor Vincit Omnia(Love conquers all.)Coniunctis viribus(Join forces)In perpetuum(Forever)
- [English: modern, light expression].
With You(With you)Side by Side(leaning in)Stay Gold(Shine on forever)
Two people are one. A bond engraved with a "set message
We recommend the style in which two rings are placed side by side to complete a single sentence. Even when you are apart, the "continued words" engraved on the other person's ring will remind you of the invisible bond between you.
- Example of a message completed by two people.
Anywhere／with You(Wherever I go, I go with you.)Always／Together（Always, together.)I am yours／You are mine(I am yours, you are mine)To the moon／and back(I love you so much I'd go to the moon and back, I love you so much I'd lose my mind)
Secret Messages" combined with birthstones
A single gemstone is fastened next to the engraving to add further meaning to the message.
At the 10th or 20th wedding anniversary, a new family birthstone or anniversary diamond can be added next to the engraving. The inside of the ring is like a "diary" that will be added to along with the couple's history.
How to engrave? [How to engrave, technical section
MITUBACI offers three methods to suit your particular needs and "what you want to experience".
Hand engraving" to express your feelings with a craftsman's tool: an exchange session that deepens the bond between two people.
Hand-hammered engraving" is a traditional method in which the craftsmen themselves pound in one letter at a time, using a metal mallet and a hammer.
This engraving method is a persistent favorite at MITUBACI.
- An "exchange session" in which the participants hit each other's rings:About half of the couples who visit MITUBACI exchange rings and engrave each other's rings. The couple feels a pleasant sense of tension, knowing that they cannot let their partner's ring fail. The time spent putting all one's heart and soul into each stroke is a moment of deep bonding that is different from the exchange of rings at a wedding.
- The luxury of "lovely unevenness."It doesn't have to be perfectly aligned like a craftsman. If your precious partner has worked hard to type the letters for you, even if they are slightly skewed, they will look like the loveliest pattern in the world. It is this "fluctuation" that gives the warmth of handmade work that no machine can produce.
- I also cherish the commitment to "own my own ring."Of course, there are also those who work on their own rings to pursue a finish that they are satisfied with. Our craftsmen provide one-on-one support, so whichever style you choose, we will help you make the best of it.
Classic beauty. Dignity engraved by "machine engraving
In "machine engraving," a craftsman engraves each letter one by one using a dial engraving machine.
Machine engraving" has a unique luster and flavor that differs from both the digital precision of laser engraving and the simplicity of hand-stamping.
- Craftsmanship engraving with a dial engraving machine: A craftsman operates the dial and engraves the metal surface with a needle that has a diamond at its tip. The grooves of the letters are deeply engraved in a V-shape, which reflects the light and makes them sparkle.
- Vintage appearance: You can enjoy a neat, classic typeface that looks like antique European jewelry. This typeface is chosen by those who prefer something that is not as rough as hand-stamping and not too modern as laser engraving.
Laser engraving" for flexible expression
Laser engraving" is a process in which a craftsman operates a laser machine and engraves text at will. The large machine makes it possible to deliver amazingly precise expressions on the same day.
We not only use the fonts we have available, but we also lodge the couple's "drawings" and "cherished symbols" directly inside the rings. MITUBACI prides itself on the flexibility that only a handmade workshop can offer, something that is difficult to achieve with ready-made brands.
- The "handwriting of the self" is painted on the spot: We will convert the letters and signatures written on the paper in our workshop into data and engrave them on the spot. Even the slightly shaky lines and peculiar quirks will become a living record of the "two of us at that time" that you will love to look back on 10 years from now.
- In advance preparation, engrave "an illustration of your dog or your own logo": Before your visit, please send us an email with an illustration of your dog carefully drawn at home or your original logo. On the same day, we will carefully bring it to life inside the ring as a precise laser engraving.
- Support for multiple languages and special Kanji characters: We can also handle Chinese kanji characters not found in Japanese and special language fonts. We give form to the "characters you want to treasure" for each and every one of our customers, who have diverse roots. This has been our sincere attitude since 1970.
Engraving is a "time capsule" for our future selves
Words and illustrations engraved on the inside of a ring are not mere decoration. They are a message to ourselves decades from now, and an important "proof of the bond" that connects us, MITUBACI, to our customers.
What Reunion Over 12 Years Taught Me
The other day, a couple visited our workshop in Sangenjaya to have their ring resized. The ring had been handmade by the couple at our workshop 12 years earlier. When our craftsmen carefully polished the ring and returned it to the couple, they looked lovingly at the engraving on the inside and smiled, saying, "It filled my heart with joy to remember the words we had decided after much deliberation at that time. The engraving is like a "time capsule" that instantly evokes memories of that time.
Even if you don't have a warranty, the engraving will be your "ID card".
There is no need to worry, "If I lose my warranty card from back then after a few decades, I might be refused maintenance ......." Inside of the ring made by MITUBACI is engraved with our logo mark, which we are very proud of. With this engraving and the data (production record) such as your name and e-mail address, even if it is 10 or 20 years later, we will immediately confirm that it is your ring and we will be faithful to you.
The joy of "adding" to the story
Engraving a ring does not end once it is engraved.
A "new birthstone" or "anniversary diamond" can be added next to the engraving to mark a 10th or 20th wedding anniversary, or when a new family member is born or welcomed into the family. The story of the engraving is added along with the couple's history. We have been swinging the hammer at this Sangenjaya location since 1970, in order to always be ready to accept the "continuation" of the story.
