What Atto does

Atto Co., Ltd. (あっと株式会社) is an Osaka-based healthcare venture founded in 2009 that develops, manufactures, and sells the Kekkan Bijin (血管美人) line of non-invasive capillary blood flow observation systems targeting the preventive / pre-symptomatic disease ('mibyou') segment of the Japanese health market. Its flagship SC-10 capillary scope is a compact, fingertip-based microscope (320x magnification, 620g body, USB/PC video output) priced at roughly one-third of conventional capillary observation equipment, paired with CAS — proprietary image analysis software developed jointly with Osaka University Faculty of Medicine that converts capillary images into numerical data in approximately three seconds using a patent-pending reaction-diffusion equation algorithm. The hardware/software stack is supplemented by a recurring consumables line (Kekkan-Bijin Special Oil), a forthcoming cloud evaluation system (CAS-RATING), and the Vascular Navi mobile app (iOS 2019, Android 2022).

Core offering

Atto (あっと株式会社) develops, manufactures, and sells the Kekkan Bijin (血管美人) capillary blood flow observation system, centered on the SC-10 fingertip microscope and the CAS image analysis software. The system non-invasively captures capillary images through the fingertip and converts them into numerical data using a proprietary reaction-diffusion equation algorithm jointly developed with Osaka University Faculty of Medicine. The company also sells the dedicated Special Oil consumable, offers equipment leasing and rental services, and distributes the Vascular Navi mobile app.

Product overview

Atto provides a comprehensive capillary analysis system centered on its flagship product line. The core offering consists of the Kekkan Bijin (血管美人) capillary scope (SC-10 model), which is a non-invasive observation device that examines capillaries through the fingertip without blood collection. This hardware connects to the CAS (Capillary Analysis System) software — the world's first capillary image analysis software developed in collaboration with Osaka University — which automatically converts capillary images to numerical data in approximately 3 seconds. The ecosystem is complemented by the cloud-based CAS-RATING system for smartphone-based result viewing, the Vascular Navi mobile app for iOS and Android, and the specialized oil consumable required for measurements. The company also offers rental services and lease options for the equipment, serving healthcare institutions, pharmacies, fitness centers, beauty salons, and corporate wellness programs.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Leica Microsystems (Danaher): Premium microscopy and digital imaging brand owned by Danaher. Comparable to Atto in optical magnification and image analysis capabilities, though Leica's focus is laboratory research microscopy rather than in-vivo clinical capillary observation.
• Carl Zeiss Meditec: German medical technology company with broad ophthalmology, microscopy, and diagnostic imaging portfolios. Comparable in imaging and lens-based diagnostic technology; not specialized in capillary observation but has resources to enter the niche.
• Terumo Corporation: Major Japanese medical device manufacturer with strong presence in hospital diagnostics and blood-related technologies. A potential strategic acquirer or competitor given overlap in hospital channel and Japanese healthcare market.
• Olympus Corporation: Japanese medical imaging and microscopy giant whose industrial/clinical microscopes and digital imaging systems broadly overlap with Atto's microscopy-based capillary platform. Could enter the capillaroscopy niche with much greater resources if the market proves attractive.
• Tanita: Japanese health-monitoring device company with consumer body-composition analyzers and corporate wellness solutions. Comparable in selling preventive-health hardware into Japanese pharmacies and corporate wellness programs, with similar channels to Atto.
• Omron Healthcare: Japanese home health-monitoring leader (blood pressure monitors, body composition, ECG). Adjacent comparable as a Japanese preventive-health device company targeting pharmacies and consumers, though with cardiovascular rather than microcirculation focus.

Direct peers

• Microvision Medical: Dutch manufacturer of capillary microscopy systems (MicroCam) for clinical capillaroscopy. Direct competitor in the capillary blood-flow imaging category with established presence in European rheumatology and microcirculation research markets.
• KK Technology: UK-based manufacturer of video capillaroscopy systems (KK Technology VCS-2000 series) widely used in rheumatology capillaroscopy. Directly comparable product category to Atto's SC-10, with overlap in the medical research and clinical use case.
• Optilia Medical: Swedish manufacturer of clinical capillaroscopy devices (Optilia Digital Capillaroscope) used for rheumatology, dermatology, and connective-tissue disease diagnosis. Most direct functional peer to Atto's Kekkan Bijin in the nailfold capillaroscopy category, though Optilia focuses on clinician-grade devices rather than Atto's non-clinical/preventive positioning.

Emerging players

• Biozoom (formerly Oak Ridge Micro-Energy): Emerging micro-spectroscopic and biophotonic health-screening player. Adjacent in applying imaging/spectroscopic techniques to non-invasive consumer health screening, with thematic overlap to Atto's vision of capillary-based health insights.
