Rexxam

What Rexxam does

Rexxam Co., Ltd. (株式会社レクザム) is a privately held diversified Japanese manufacturer founded in 1960 in Kagawa Prefecture (originally as Ryusho Sangyo), headquartered in Takamatsu with operations spanning more than 12 global sites across Japan, China (Shenzhen, Suzhou/Taicang, Dongguan, Kunming), Thailand, India (Pradesh and a new Chennai facility planned for spring 2026), the Czech Republic, and the Netherlands. The company operates across five primary business segments: ophthalmic diagnostic instruments (autorefractometers such as ACCUREF K-900/R-800, non-contact tonometers NCT-200, lensometers, slit lamps, and the WorkStation OZY launched in May 2024); electronics manufacturing equipment (the Sherlock series of PCB automated optical inspection systems, Watson QR-800 laser QR printers, Pegasus AOI systems, and Hummingbird-550 vision inspection); semiconductor handling (vacuum- and heat-resistant wafer transfer robots, load ports, and hoop transfer robots); bio-research analytical instruments (Bio-REX Scan200 evanescent scanner and Bio-REX SPR300F surface plasmon resonance system); and precision industrial equipment (supercritical dryers, Merex landslide monitoring systems, precision chillers, Clasper automotive fixtures). Smaller consumer lines include Sanuki Beer (Sanuki Brewery established 1996) and ski boots. Underlying capabilities are in mechatronics, optics, bio-sensing, and communication technologies.

Rexxam sells primarily through a B2B enterprise field-sales motion, quoting custom pricing to hospitals, ambulatory surgical centers, electronics manufacturers, and semiconductor fabs. Distribution is supported by the company's own global manufacturing footprint, which enables localized supply and supply-chain resilience, and by direct sales offices in Japan (Tokyo and Takamatsu). Marketing is brand-led via trade shows (Nepcon Japan, Machine Elements Technology Exhibition), Japanese broadcast TV/radio CM, a YouTube channel (@rexxam1736), and a heavy regional sports-sponsorship program including ownership of naming rights for Kamatamare Sanuki (J3 football club), Rexxam Ballpark Marugame, Yashima Rexxam Field, and Rexxam Stadium, plus support for Kagawa Five Arrows (B.League basketball) and Kagawa Olive Guyners baseball.

Rexxam is led by President Okano and Executive Vice President / Production Headquarters Director Sumita Hiroyuki, both long-tenured executives, and was selected by Japan's Ministry of Economy, Trade and Industry as a 'Regional Future Driving Company.' The company carries no outside institutional investors, no public listing, and discloses no consolidated revenue. Recent capital allocation has focused on geographic capacity buildouts (India, Thailand), factory automation (Ayagawa automotive parts plant scheduled for July 2026), and product refreshes in ophthalmic and bio-instrument lines.
