From machining next-gen turbine blades to pioneering additive manufacturing and engineering services, AeroEdge propels Japan’s industrial future—cutting metal, forging innovation, and setting the aerospace bar higher.
To begin, I’d like to discuss the Japanese aerospace industry—its opportunities and challenges. After the war, Japan steadily became indispensable as a global partner in aviation. A well-known example is the Boeing 787, which integrates advanced composites and precision systems sourced from Japan. Today, the Japanese aerospace sector continues to anchor international supply chains, while advancing additive manufacturing and pushing the frontier of environmental sustainability. What is your assessment of the industry’s current status, its future, and the key trends driving it?
Historically, Japan’s strength lay in precision manufacturing—supported by the country’s culture of diligence, commitment to on-time delivery, and uncompromising quality. These qualities enabled Japanese companies to play critical roles in global aerospace programs. We have also built expertise in advanced composite materials and titanium products, with companies such as Osaka Titanium and producers of titanium sponge exemplifying this strength.
However, there are structural challenges. Since the postwar era, Japan’s aerospace sector has been subject to certain restrictions. Moreover, our industry lacks domestic OEMs and relies heavily on a small number of Tier-1 heavy industry players. That model was acceptable in the past, but I believe the future will demand a different approach.
As for AeroEdge specifically, we focus on building a truly global business rather than depending on orders from Japanese heavy industry. Our main business is supplying titanium aluminide (TiAl) blades and related parts for leading global aerospace companies. Our goal is to compete as a world-class manufacturer from Japan, not simply as a subcontractor.
I’d like to move to another macro theme: Japan’s demographic challenge. The country faces a projected 12% labor shortage by 2040, with the population expected to fall to 100 million and a shortfall of some 700,000 engineers by 2030. How is this issue affecting your industry and your company, and how are your education or Ph.D.-level initiatives—such as AM Native—helping to address it?
The shrinking workforce is indeed a serious issue. At AeroEdge we respond on two levels. First, in research and development we collaborate not only with Japanese institutions but also with leading organizations in the United Kingdom, Germany, and France. This global R&D network broadens our talent pipeline and knowledge base.
Second, in hiring we actively recruit internationally. We began bringing in foreign engineers and graduate students about a few years ago and will continue to do so. For highly skilled roles—such as engineers, IT specialists, and technical back-office positions—Japan still offers sufficient talent when we combine domestic and international recruitment.
Where we face more difficulty is in factory shift work. Japanese workers increasingly prefer to avoid night or holiday shifts, especially during long national holiday periods such as Golden Week and New Year. We even conducted an internal survey, and nearly 100% of employees said they would not work during those holidays. This cultural preference challenges any company that must meet global production schedules. We therefore look seriously at automation and at rethinking traditional work-holiday practices so that Japan can align more closely with international industrial standards.
Let’s talk about your company’s philosophy. You’ve described AeroEdge as a “revolutionary act,” breaking Japan’s subcontractor mold by becoming a Tier-1 supplier to Safran and pioneering titanium aluminide blade production. Could you explain this vision for our readers?
From the beginning, we set out to be different. I encourage our people to think freely and to challenge convention—even if that means failing at times. Trying something new always involves risk, but even failure provides lessons that lead to the next success. We founded AeroEdge ten years ago with this mindset. A recent milestone illustrates how far we have come: traditionally, machining companies purchase their raw materials from suppliers. We decided to produce our own titanium aluminide material in-house, then machine it and deliver finished products ourselves. This vertical integration makes us the sole global supplier capable of covering the entire process, from raw material to finished component, for certain customers. It is a true game-changer in our field.
Your partnership with Safran, co-developer of the CFM LEAP engine used in Airbus and Boeing aircraft, is especially impressive. A relatively small Japanese SME has become one of only two global mass producers of TiAl blades, reportedly only one source outside France among the LEAP engine blade market. How did you achieve this?
When Safran began developing the LEAP engine, they invited several companies worldwide to compete. We all carried out trial machining, but AeroEdge was the only company that consistently met Safran’s stringent quality and delivery requirements. That led to prototype production and eventually to a long-term contract. It was a global competition, and our ability to meet the highest technical standards secured the partnership.
Titanium aluminide is a lightweight, heat-resistant but difficult-to-machine material. Your Ashikaga facility, with its in-house cutting tool development and 5-axis machining centers, is said to be central to mastering these challenges. Could you elaborate?
We spun off from Kikuchi Gear, which originally owned the Ashikaga site. This location was inherited when we established AeroEdge. While I personally believe that sites closer to major ports or airports—such as Kobe, Nagoya, or Fukuoka—would offer logistical advantages, Ashikaga has allowed us to build deep technical capability.
Technologically, success has come through relentless trial and error. We have also drawn on Japan’s strong automotive and motorsports sectors, which demand extremely high standards of quality and punctual delivery. Working with companies in those sectors sharpened our processes and helped us achieve the precision necessary for aerospace titanium aluminide components.
You have announced two major diversification projects—Part A and Part B—representing significant investments in new, non-LEAP engine programs. How will these initiatives strengthen your business?
Part A and Part B are indeed independent from the LEAP program. Each is a distinct jet engine project with different aircraft and engine makers. The key requirements from these new partners are quality, speed, and mass-production capability, all with a significantly lower carbon footprint. Traditionally, producing engine materials involves chemical or electrically intensive processes. We use advanced machining and proprietary tooling to avoid those steps, reducing CO₂ emissions while meeting exacting production schedules. These projects will expand our customer base and reinforce our leadership in environmentally responsible manufacturing. Importantly, such achievements are valued more highly by overseas customers—where carbon-reduction standards are mandatory—than in Japan, and we see that as a growth opportunity.
AeroEdge Headquarters
Beyond aerospace, you are exploring additive manufacturing for railway components, medical applications, and even e-vehicle and flying-car supply chains. Which areas do you see as the most promising?
From a technological standpoint, e-vehicles and energy fields such as gas turbines are natural extensions of our core capabilities. However, our corporate philosophy emphasizes social contribution. That is why we are especially drawn to the medical sector, where our technology can directly improve quality of life and help people in need.
Looking at your international activities, you collaborate with organizations such as Germany’s Fraunhofer Institute, Silicon Valley start-up 3DOS, and Cambridge-based innovators. You are also involved in joint France-Japan research projects. Where do you see your global expansion focusing—more collaborations, new OEM customers, or overseas facilities?
All of those elements are part of the picture, but two priorities stand out. First, Japanese companies—including ours—must strengthen their ability to meet special processing requirements and obtain international certifications. Europe, particularly France and the UK, is ahead in creating structured pathways and even commercial platforms to help companies gain these certifications. We are working to catch up and build robust technology pipelines in that area.
Second, we want to help create a stronger, more secure aerospace supply chain in Japan itself. Today, many Japanese suppliers struggle to meet the stringent cybersecurity and system standards demanded by U.S. and European customers. AeroEdge already complies with these standards, and we are working with partners such as Neutreeno to bring our broader supply network up to the same level, including precise carbon-emissions measurement from Scope 1 onward.
Finally, if we return to interview you five years from now, what achievements would you like to share?
Five years from now, I aim for AeroEdge to be recognized globally as a technology leader and as a trusted partner with a fully international footprint. I want us to have broadened our customer base beyond aerospace into sectors such as energy, e-mobility, and medical technology, while making measurable contributions to sustainability and to society at large. Most of all, I hope to show that a Japanese company can redefine manufacturing on a global scale—proving that innovation, responsibility, and growth can go hand in hand.
