Message from the President
We are deeply honored to have received the Wakayama Prefecture 100-Year Enterprise Award, and offer our heartfelt thanks.
Since our founding, we have devoted ourselves faithfully to the craft of seal-making, giving form to each customer's wishes one by one. We could only have walked this hundred-year path with the support of so many people.
In the hundred years to come, we will continue to stand beside the people of our community with the same unchanging sincerity and dedication.

History
In September of Meiji 3 (1870), the Edict Permitting Commoners' Surnames was issued, followed in Meiji 8 (1875) by the Edict Mandating Commoners' Surnames, ushering in an age in which every Japanese citizen was required to hold a surname.
Amid the decline of the rapeseed-oil trade and a search for the family's next path, and foreseeing the demand for registered personal seals created by the new seal registration system, as well as the demand for rubber stamps driven by commercial growth, founder Heitaro Miyamoto, together with his eldest son Heiichiro, established a seal-engraving shop at 1-1 Motoderamachi, Wakayama City.
Wakayama Seal-Engraving Guild 20th Anniversary Celebration (October 15, Showa 10 [1935], at Wakanoura). The guild's name suggests it already existed around Taisho 5 (1916).
Succeeded the family business at 1-1 Motoderamachi, Wakayama City, alongside his father Heitaro. He also served as head of the trade guild and trained many apprentices, including live-in craftsmen.
Expanded the client base through storefronts in shopping arcades and the Marushou department store, along with rubber-stamp deliveries. Introduced printing presses, making New Year's card printing a core product. As mechanization streamlined production, greater emphasis was also placed on in-store retail sales.
To expand the shop, the head store was relocated to 113 Saikamachi, Wakayama City.
Took over management from the 3rd generation, but sensing the decline of department stores and shopping arcades, moved away from a wholesale-delivery-centered model and fundamentally changed the sales approach.
Anticipating the shift toward a car-based society, planned openings in commercial complexes with parking. Opened a store at Aeon Mall Hineno in 1995, followed by Aeon Mall Wakayama in 2014.
The Aeon Mall Wakayama store — a symbol of the new sales approach built around a car-based society.
Advanced mechanization and digitalization, and actively embraced progress in AI.
In addition to the core seal-engraving business, opened a real estate business founded on two national qualifications. Alongside the seal-engraving trade, also focused on online outreach, including sharing a personal passion for Wakayama's history.
Received the Wakayama Prefecture 100-Year Enterprise Award.

Even amid the headwinds of the digital age, we cherish the weight of "contracts and registered seals," and will continue to strive toward the next hundred years.
We were honored to be recognized in the same year as Kiyo Bank and Kinokuni Shinkin Bank, our neighbors from the same Edo-period merchant district.

Ties to the Community
Supported by the climate of Kishu and the warmth of the people who live here, we have been able to continue our business for a hundred years.
We have cherished dialogue with each and every customer, and have also devoted ourselves to local events and cultural activities.
We will continue to put down roots in Wakayama and walk this path together with our community.
Our ancestors conducted business in a merchant district called Uchimachi, which extends north from the same Wakayama Castle,
trading under the shop name "Mitsuiya" since the Edo period.
About Mitsuiya
Toward the Next Hundred Years
With gratitude in our hearts for everyone who has supported us, we will continue to put our whole heart into every piece of work we do.
Through seal-making, real estate, and the sharing of history and culture, we promise to continue standing beside Wakayama's future.
