Choosing high-barrier niches

JEOL’s electron-beam writers are used in making the gratings in DFB lasers for optical communications. Spot-beam orders and sales rose in the year ended March 2026, while fewer mask writers were sold and industrial-equipment sales declined. Following what each machine patterns, and where it sits in its customer’s production process, reveals different demand conditions within semiconductor-related equipment.

Nittobo supplies glass cloth woven from fine yarn for use in circuit-board materials. NE/NER glass for high-speed transmission and T glass for controlling package-substrate warpage meet different requirements. Following electronic-materials growth in the year ended March 2026, the September 2026 report describes capacity investment and outside collaboration in weaving. Material composition, manufacturing processes and the division of production work together explain how Nittobo serves AI-related demand.

HORIBA establishes a gas-flow reference from mass and time and supplies flow-control devices for semiconductor production equipment. Expanding calibration facilities adds a different capability from increasing product output. In FY2025, Materials & Semiconductor sales grew while operating income declined, mainly because of accelerated R&D and technology investment. The work of making measurements reliable, and the cost of that work, help explain the business behind the devices.

H.U. Group’s testing and related services measure specimens entrusted by medical institutions and report the results. Operating profit was ¥31m in the year ended March 2026. The company cites growth in genetic and specialized testing, price adjustments and improved testing operations. Segment depreciation was ¥13.598bn, showing the costs behind keeping equipment and people at work. Consolidated operating profit of ¥4.780bn covers a different scope, including diagnostic reagents, other businesses and corporate-cost adjustments.

Nichias distinguishes building space from installed equipment capacity in its expansion plan for high-performance products. Orders rose while sales fell in the year ended March 2026. Factory readiness, customer orders and recognized revenue are separate measures to examine.

SMC combines standard-product inventory, custom-order capability and connected manufacturing processes. Sales grew in the year ended March 2026, but the operating margin fell. Turning product variety into both timely delivery and profitability remains the challenge.

Hamamatsu supplies systems that narrow down a chip’s failure location between electrical testing and physical root-cause analysis with an electron microscope. Its May 2025 TD Imaging release describes detecting localized heat through laser reflectance to locate defects non-destructively. Semiconductor failure-analysis sales were ¥10.4bn in FY2025. Elsewhere in the group, medical-bio sales declined, while higher costs and other factors reduced operating profit. The business combines light-detection technology into equipment that helps customers take the next analytical step.

Ebara supplies semiconductor factories with both pumps that remove gas from processing spaces and equipment that works on wafers. CMP accounts for 62% of Precision Machinery revenue. As chip structures become more layered, surface planarization and edge quality before bonding give polishing a broader role.

Kurita combines equipment handover followed by maintenance and chemicals with water supply using equipment it owns. The latter involves construction, investment and operation, while contract-termination settlement gains are recorded separately from revenue. Recurring contract-based services’ 17% revenue share and the broader service-business ratio of 72.1% measure different things. Asset ownership and operating responsibilities reveal how customer relationships continue.

Daifuku builds material-handling systems to suit customer sites, then provides inspections, parts, modifications and renewal. In FY2025, construction revenue recognized over time was ¥490,548 million, about 74% of consolidated sales of ¥660,724 million. Orders and project work can fall in different years, while cost estimates and execution affect project profitability. Service sales were ¥176.6bn, or 27% of consolidated sales. Service and construction revenue are different classifications and cannot be added together; service includes both period-based contracts and individual jobs.

Nabtesco supplies precision reduction gears to robot makers, and brakes and door-operating systems to rail operators and train builders. Its building automatic doors, aircraft equipment, marine controls and packaging machines also work inside customers’ equipment and operating sites. FY2025 continuing operations generated ¥307.9bn in revenue and ¥20.7bn in operating profit. Accessibility Solutions contributed ¥110.7bn of revenue, Transport Solutions ¥100.5bn, Component Solutions ¥79.3bn and Manufacturing Solutions ¥17.4bn. Company-estimated product market shares and these four businesses’ revenue totals measure different things.

Advantest sells test systems to semiconductor and electronic-component manufacturers, then supplies support and consumables such as interface boards. In FY2025, ended March 2026, demand for advanced-chip testers and supply capability grew while mature-chip tester demand remained soft. Sales of ¥1.1286tn, operating income of ¥499.1bn and a 44.2% operating margin reflect that demand split and product mix.

Sysmex’s work continues after installation through reagents, reference materials, scientific information and customer care. Its 79.4% stable-revenue measure includes reagents, service/support and other sales; it is not a subscription-only share. Continuing supplies and support help explain the business behind ¥500.0bn of FY2025 sales.

Capacitors help reduce noise and support sudden current demand inside electronic circuits. Murata brings materials and manufacturing capabilities to making these parts. In the year ended March 2026, capacitors grew across applications including servers, while RF and communications revenue fell. Demand differs by component and application, even within the same equipment market.

Alongside water-related products, TOTO supplies ceramic components to equipment manufacturers. Electrostatic chucks hold wafers, AD coatings protect equipment surfaces, and engineering ceramics support precise motion. Their functions and production methods differ. Engineering ceramics draw on sanitary-ware forming and firing control and faucet polishing. The Advanced Ceramics Business generated ¥50.3bn in sales and ¥20.4bn in operating profit in FY2024, then reported record sales and profit in FY2025. In April 2026, TOTO said it had decided on about ¥30bn of investment to expand electrostatic-chuck and AD-component R&D and production capacity.

HOYA’s mask blanks enter semiconductor circuit-patterning processes; its HDD glass substrates become the bases of magnetic disks. The company emphasizes customer-specific technical alignment in the first business and consistent high-volume production in the second. Revenue was ¥947.7bn in the year ended March 2026, with a company-reported mix of 62% Life Care and 38% Information Technology. Supplying lenses to optical retailers and operating Eyecity stores are also important parts of the group. Initial-phase investment in two new EUV and HDD plants is planned at roughly ¥92bn combined. Looking at customer processes and supply requirements helps explain the strengths of the businesses that expanded from optical glass.
