The company behind Ray-Ban has been quietly buying shares in Nikon, the iconic Japanese camera maker. What started at 5% in late 2024 has swelled to 19.61% in just 18 months, one step away from the 20% regulatory cap. Behind this "friendly accumulation" lies a quarter-century partnership and a strategy built around the future of smart glasses. This is no hostile takeover; it's the natural evolution of one of the longest-running optical alliances in the industry.

Who Is EssilorLuxottica?

On April 14, 2026, a regulatory filing revealed that EssilorLuxottica, the Franco-Italian eyewear behemoth headquartered in Paris, had increased its stake in Nikon from 18.59% to 19.61%.

EssilorLuxottica is a name most people don't recognize, but its brands are everywhere. Ray-Ban, Oakley, Persol, and licensed eyewear for Prada, Chanel, and Giorgio Armani are all under its umbrella. On the lens side, it owns Varilux (the world's top progressive lens brand) and Transitions (photochromic lenses). With a market capitalization of roughly €100 billion ($108 billion), it ranks among France's largest companies and is a constituent of the CAC 40 index.

Nikon, by comparison, has a market cap of about ¥650 billion ($4.1 billion), roughly one-twenty-fifth the size of its new top shareholder.

This Is Not a Hostile Takeover

To be clear, EssilorLuxottica's stake-building in Nikon is fundamentally different from a hostile acquisition.

The two companies share a 25-year joint venture history. EssilorLuxottica CEO Francesco Milleri has publicly stated that Japan is "strategically important" and that the company wants to "spread the value of Made-in-Japan globally." Nikon itself issued an official press release in October 2025 announcing the change in its largest shareholder, voluntarily disclosing that EssilorLuxottica had obtained FEFTA clearance to acquire up to 20%, the kind of transparency that doesn't happen in hostile relationships.

EssilorLuxottica has not demanded board representation, has not pushed for management changes, and has not issued any activist-style demands. The stated purpose remains "long-term pure investment" throughout, a signal of strategic alignment rather than aggressive intervention.

A Steady, Methodical Accumulation

EssilorLuxottica's stake-building in Nikon has been remarkably systematic:

  • October 2024: 5.10% → 7.38% → 8.45%
  • September 2025: 9.47% → 9.62%
  • October 2025: 10.59% (became top shareholder; received Japanese government clearance to acquire up to 20%)
  • November 2025: 11.84%
  • February 2026: 14.20% → 15.41%
  • March 2026: 17.53%
  • April 2026: 18.59% → 19.61% (disclosed today)

The stated purpose throughout has been "long-term pure investment."

A 25-Year Partnership as the Foundation

This investment didn't emerge out of thin air. Nikon and EssilorLuxottica (then Essilor International) established a 50/50 joint venture called Nikon-Essilor Co., Ltd. in 2000, developing and selling eyeglass lenses under the Nikon brand in Japan. In February 2026, the JV launched the "Z Series", single-vision lenses using camera lens design technology, and the flagship "Eyedition Series," described as the finest eyeglass lenses in Nikon's history.

So EssilorLuxottica isn't a stranger making a hostile approach. It's a quarter-century partner deepening an already productive relationship.

Smart Glasses: Where Nikon's Optics Could Change the Game

The strategic context goes far beyond traditional eyewear. EssilorLuxottica is at the forefront of the smart glasses revolution through its partnership with Meta.

The Ray-Ban Meta smart glasses, launched in their second generation in 2023, became a surprise hit with integrated cameras, speakers, and Meta AI voice assistant. In September 2025, Meta unveiled the Ray-Ban Meta Display at $799, featuring a 600×600 pixel display integrated into the right lens, 5,000-nit brightness, 90Hz refresh rate, and a neural wristband for gesture control. The company also expanded into sports with Oakley Meta glasses.

This is where Nikon's optical expertise becomes strategically significant. Nikon has over a century of experience designing and manufacturing camera lenses, with proprietary technologies like Nano Crystal Coat for reducing lens flare. As smart glasses evolve to require prescription lens compatibility, higher-resolution displays, and more sophisticated optical systems, Nikon's precision optics know-how becomes increasingly valuable.

Nikon also manufactures semiconductor lithography equipment (steppers and scanners) that etch nanometer-scale circuit patterns onto silicon wafers. This ultra-precision optical engineering could prove relevant for integrating miniature displays and sensors into smart eyewear lenses.

Japan's National Security Gate: Why 20% Is the Ceiling

Nikon isn't just a camera company. Its semiconductor lithography equipment is classified as a "core sector" under Japan's Foreign Exchange and Foreign Trade Act (FEFTA), the country's national security screening framework for foreign investment.

Under FEFTA, any foreign entity seeking to hold more than 10% of a "core sector" company must submit a prior notification and undergo government review. EssilorLuxottica cleared this hurdle in October 2025, obtaining authorization to acquire up to 20% of Nikon's voting rights.

At 19.61%, EssilorLuxottica has nearly reached that authorized ceiling. Going beyond 20% would require a fresh round of negotiations with Japanese authorities, a process that could prove politically sensitive given Nikon's role in semiconductor manufacturing, a sector at the heart of the U.S.-China tech rivalry.

Japan faces a delicate balancing act: welcoming foreign investment to boost market attractiveness while guarding against technology leakage. Officials have also flagged the theoretical risk that EssilorLuxottica could resell shares to a third party, say, a Chinese company, potentially creating a backdoor for sensitive technology transfer.

The Buffett Effect and TSE Reforms: Why Foreign Money Is Flooding Japan

EssilorLuxottica's investment in Nikon is part of a much larger wave.

In 2023, legendary investor Warren Buffett visited Japan and declared his interest in additional Japanese investments after increasing his stakes in Japan's five major trading houses. This "Buffett Effect" sent a powerful signal to global investors that Japan was undervalued and open for business.

The Tokyo Stock Exchange amplified this momentum. Since 2023, the TSE has pressured companies trading below a price-to-book ratio (PBR) of 1.0 to articulate concrete plans for improving capital efficiency, including share buybacks, dividend increases, and divestiture of underperforming assets. This corporate governance reform has been transformational, driving a surge in shareholder returns.

By the end of fiscal 2024, foreign ownership of Japanese equities hit a record 32.4%. Activist funds like Elliott Investment Management have moved aggressively, demanding a $2 billion buyback from shipping giant Mitsui O.S.K. Lines. In 2025, Japan's TOPIX outperformed the S&P 500, leading some analysts to declare a "new golden age" for Japanese stocks.

Foreign investors were net buyers of Japanese equities to the tune of ¥7.3 trillion ($46 billion) during the 18-month period from January 2023 to June 2024, underscoring the scale of this shift.

What This Means for Nikon

Nikon has had a turbulent few years. While its mirrorless camera lineup (Z8, Z9, ZR) has earned critical acclaim, the semiconductor lithography division trails far behind industry leader ASML, and newer ventures like 3D printing have struggled. The company revised its fiscal 2025 outlook to a significant operating loss due to impairment charges.

Having EssilorLuxottica as its largest shareholder offers several potential benefits. First, the global retail network, thousands of stores including LensCrafters, Sunglass Hut, and OPSM across approximately 60 countries, provides a massive distribution channel for Nikon-branded lenses. Second, collaboration in smart glasses could open an entirely new revenue stream.

However, the "long-term pure investment" label suggests EssilorLuxottica isn't seeking board seats or management control. The relationship appears to be one of strategic alignment rather than activist pressure, a friendly embrace between an optical technology powerhouse and the world's eyewear king.

What to Watch Next

At 19.61%, the authorized 20% ceiling is within touching distance. Key questions going forward:

Will EssilorLuxottica seek to go beyond 20%? If so, a new round of FEFTA negotiations would signal a deepening commitment that goes beyond passive investment. If it stops at 20%, the relationship may remain a strategic partnership without formal integration.

Will smart glasses collaboration be announced? The JV currently focuses on traditional eyeglass lenses. An official announcement of collaboration on AR lens design or smart eyewear optics would reveal the true strategic intent behind the share accumulation.

How will Japan balance security and openness? The FEFTA framework's handling of the EssilorLuxottica-Nikon case will serve as a precedent for future foreign investments in Japan's technology sector. Too strict, and it discourages capital inflows. Too lenient, and it risks technology leakage in an increasingly tense geopolitical environment.

In May 2026, speculation intensified that EssilorLuxottica might move to take full control of Nikon, and Nikon's shares surged to a five-year high. Neither company issued any new official statement, however, and EssilorLuxottica has continued to frame its holding as a long-term passive investment.

In Japan, opinion is split between excitement about a global brand investing in a beloved optics company and worry about technology outflow and loss of independence. How does your country view large foreign investments in domestic tech companies? We'd love to hear your perspective.
