In an industry that often confuses newness with progress, Masunaga Optical Mfg. Co., Ltd. has spent 120 years doing the opposite. The Japanese eyewear house, founded in 1905 in Fukui, has never issued a bold rebrand, never chased a trend cycle, and never outsourced the parts of its production that matter most. That kind of consistency is either stubbornness or conviction — and in Masunaga’s case, the results speak for themselves.

The brand recently celebrated its 120th anniversary together with Marq Optic Gallery in Kuala Lumpur, a city it has had a presence in for more than three decades. The event provided media and invited guests with a curated showcase of limited anniversary pieces and some of the house’s most exceptional work, including full 18K gold eyewear handcrafted entirely in Fukui. Frames that, if you encountered them without context, you would know were made by someone who genuinely cared.

To understand Masunaga is to understand Fukui. Today, the prefecture in north-central Japan is recognised as one of the world’s foremost eyewear manufacturing centres — a region whose name carries the same weight in optical circles that certain Italian towns carry in the world of leather goods. But that reputation was not always assured. At the turn of the 20th century, eyewear production in Japan was fragmented and inconsistent. It was Masunaga’s founder, Gozaemon Masunaga, who introduced the idea that would change everything: unite craftsmen under one roof, standardise techniques, and hold every stage of production to the same exacting standard. Quality, in his view, was not a selling point. It was a moral position.

That founding philosophy has never been retired. More than a century later, Masunaga still oversees every step of production in-house — from initial design, mold-making, and metalworking through to soldering, polishing, and final assembly. Each frame passes through more than 200 manual steps before it leaves Fukui. The vertically integrated system means that when a prototype is being developed, artisans can refine the fit and feel on the spot before anything moves into full production — a degree of control that is simply not possible when manufacturing is distributed across suppliers. The artisans working in Fukui today have inherited their techniques from those who came before them, in the most literal sense. The result is eyewear defined not by volume or visibility, but by balance: purposeful proportions, impeccable fit, and the kind of quiet confidence that only comes from making the same thing very well for a very long time.

For Yasunori Masunaga, fourth-generation Brand Owner of Masunaga Optical Mfg. Co., Ltd., the Kuala Lumpur anniversary event carried particular meaning. Malaysia is not a new market for the brand — it has been long-standing.

“Malaysia has been part of Masunaga’s journey for more than 30 years, and we have seen a growing appreciation for quality and authenticity. Today, Malaysia is a market with strong potential. As we enter our 120th year, we see this as an important moment to deepen our presence, share the story of Fukui craftsmanship, and grow the Masunaga name with a new generation who value eyewear made to last.”

That ambition is shared by Marq Optic Gallery, Masunaga’s long-standing retail partner in Malaysia and a curator of fine eyewear whose own philosophy aligns with it. For Masato Nakane, Brand Owner of Marq Optic Gallery, the anniversary is less a milestone to celebrate than a story to tell more widely.

“Masunaga is never about spectacle. It is about restraint, heritage, and integrity. After more than 30 years in Malaysia, this is the right time to bring Masunaga’s story forward — to allow more people to understand the depth of craftsmanship that comes from Fukui, Japan.”

The Edition 120 collection — a series of five frames produced to mark the anniversary — offered the most tangible expression of that philosophy on the evening. The two models revealed so far are the Radio City, refined silhouette with smooth, concise lines, and the Lex, a square frame with a calm, classic composure. Both are built from titanium fronts with temples that fuse titanium and 18K gold using a direct bonding technique developed by Masunaga — a process that joins two structurally and visually distinct materials into a seamless two-tone finish that manages to feel both luxurious and understated simultaneously. Each left temple is engraved with “Edition 120”, a mark so discreet it functions more as a private acknowledgement than a public declaration. Three further models in the collection are yet to be revealed.

These are not commemorative pieces in the conventional sense — not frames dressed in special colourways or stamped with anniversary logos. They are Masunaga working at the top of its register, the accumulated refinement of 12 decades expressed through materials and techniques that most eyewear brands would not have the in-house capability to execute. The 18K gold and titanium bonding technology alone represents years of proprietary development — a reminder that what looks effortlessly simple is, in Masunaga’s case, the product of anything but.

In a market increasingly saturated with eyewear that prioritises logo recognition over the quality of what sits behind it, there is something quietly radical about a house that has never wavered from the belief that the frame itself is the point. After 120 years, Masunaga has earned the right to let that conviction speak for itself.
