What Koito Manufacturing makes

Koito Manufacturing designs and produces automotive lighting systems: headlamps, rear combination lamps, fog lamps, turn signal lamps, interior lighting, and side-marker units. Lighting is the core of the business, accounting for the substantial majority of consolidated revenue, and the company operates across every major segment of the market, from standard halogen and LED units to the matrix LED and laser headlamp systems now appearing on premium vehicle lines. Koito's own product pages describe ADB (Adaptive Driving Beam) as a current production technology, which modulates beam shape in real time to avoid blinding oncoming drivers.

In January 2025, Koito completed the acquisition of Cepton, Inc., a NASDAQ-listed LiDAR sensor company headquartered in California. Cepton's solid-state lidar units use a micro-motion technology approach and had previously been selected by General Motors for a production ADAS program. Under Koito ownership, Cepton is being positioned as the group's sensing arm alongside its lighting portfolio, an acknowledgment that automotive lighting and perception are converging around the vehicle's front-end assembly. The company also produces aircraft parts and electrical equipment, though automotive lighting represents the dominant share of sales.

The company's global structure reflects its position as a Tier-1 supplier to major OEMs: wholly owned North American Lighting, Inc. (approximately 5,300 employees, plants in Illinois, Alabama, and Indiana, technical center in Farmington Hills, Michigan) handles Americas production; Koito Czech s.r.o. in Zatec serves Europe; subsidiaries in Thailand, Indonesia, Malaysia, and India cover Southeast Asia; and operations in Guangzhou and Hubei serve the China market following restructuring in 2025. Each regional entity manufactures lighting to local OEM specifications.

Financial performance

Koito reported consolidated net sales of ¥947.6B for the fiscal year ended March 31, 2026 (FY2025 in its fiscal calendar), a 3.4% increase over the prior year's ¥916.7B. The Berylls Top-100 automotive supplier study places automotive-segment revenue at approximately EUR 5,515M for the same period, ranking Koito 62nd globally. Operating profit reached ¥51.4B, up 14.6% year on year, with an operating margin of 5.4%. The company employs 21,507 people on a consolidated basis as of March 31, 2026.

Net profit fell sharply, to ¥16.5B from ¥46.2B the prior year, as the company recognized extraordinary impairment losses related to the Cepton LiDAR business and China operations. These were below-the-line items; the operating business itself improved. Revenue growth was driven by new orders across global regions and higher volumes on hybrid electric vehicle programs, per the company's May 2026 earnings disclosure.

For FY2026, the company's own Q1 report (April-June 2026) showed net sales of ¥240.9B, up 9.6% year on year, and operating profit up 39.1%, signaling a strong recovery. Full-year guidance projects net sales of ¥933.0B and operating profit of ¥60.0B, an implied margin of approximately 6.4%.

Ownership and history

Genrokuro Koito founded the business in 1915, initially supplying Fresnel lenses for railway signal lamps -- an origin in precision optics, not automotive. The company entered automotive lighting in 1936 when it supplied headlamps for the AA passenger car produced by Toyoda Automatic Loom Works, the company that became Toyota Motor Corporation. That relationship has continued for 90 years and shaped Koito's development into the global Tier-1 it is today. Koito incorporated in 1936 and listed on the Tokyo Stock Exchange, where it trades on the Prime Market under code 7276.

The company is headquartered at Sumitomo Fudosan Osaki Twin Bldg. East in Shinagawa-ku, Tokyo. Toyota Motor Corporation has historically held a significant ownership stake, reflecting the depth of the customer relationship. Masahiro Otake serves as Chairman and CEO; Michiaki Kato serves as President and COO, per the company's own executive management page.

Certifications and quality

Koito's sustainability disclosures identify quality improvement as a core materiality, and the company supplies OEMs that mandate IATF 16949 certification across their Tier-1 base, including Toyota programs in every production region. ISO 14001 environmental management is referenced across the group's sustainability reporting. Specific certificate dates were not published on the English-language sections of the company's site as of the verification date.

Known customers

North American Lighting, Inc., Koito's wholly owned US subsidiary, is described in its own materials as "the largest lighting supplier to automotive OEMs in North America," consistent with the breadth of its Illinois and Alabama production footprint.
