What Afin does

Afin (株式会社アファン / Kabushiki Kaisha Afan) is a privately held Japanese software company founded in 2003 by Yoichi Fujikawa in Mitaka City, Tokyo, that develops and sells the Musashigyo (武者視行) vision training software. The product is a Windows 10/11 desktop application delivered on a USB memory stick, targeted exclusively at enterprise/business customers since the October 2024 discontinuation of personal licensing. It trains dynamic visual acuity, peripheral vision, visual cognition, spatial cognition, and visual memory through five computer-based perceptual drills, with a built-in test mode that records results for up to 300 users per license and visualizes weak points via laser charts. Single-PC-per-license delivery and a memory-stick DRM anchor the technology stack.

The company sells via direct website contact for enterprises and operates a school advisory program that channels vision training coaching to sports clubs, universities, and training institutions. Documented customers span automotive OEMs (Toyota, Nissan, SUBARU, Mazda) for visual inspection quality control, electronics manufacturers (Yamaha, Panasonic), transportation safety operators (Yamato Transport, taxi associations), professional sports teams (Saitama Seibu Lions, FC Tokyo, TOM'S), universities (Waseda, Meiji, Asia), medical institutions (Shizuoka Chutoa En, Ibaraki Prefectural Medical University), and local governments (Mitaka, Tachikawa) for elderly prevention programs. The product carries Japan Patent No. 4813080 and is backed by industry-government-academia NIRS brain activity research with NICT and multiple Japanese universities.

Revenue mechanics are based on one-time/perpetual enterprise licenses priced via direct negotiation rather than subscription, with no publicly disclosed pricing. Geographic scope is domestic Japan (Tokyo metropolitan area focus), and the company has no mobile app, no API, and no external investors. With 1-10 employees and a founder-led structure unchanged since inception, Afin operates as a micro-enterprise around a single product line sustained by celebrity endorsements, media exposure, and academic partnerships.

Direct peers

• Senaptec: Senaptec provides sensory performance and vision training software (HawkEye, Sensory Station) for athletes and sports organizations. It is the closest Western analog to Afin's vision training software, addressing reaction, peripheral vision, and visual cognition for sports performance.
• NeuroTracker: NeuroTracker delivers 3D multiple-object-tracking cognitive training software used across professional sports, military, and clinical applications. Overlaps with Afin in the cognitive / perceptual training domain, particularly for elite athlete use cases.
• Dynavision International: Dynavision produces visual-motor reaction training equipment and software (D2) used for sports performance, rehabilitation, and tactical training. Highly comparable to Afin in training peripheral awareness, reaction speed, and visual-motor coordination.
• RightEye: RightEye offers eye-tracking-based vision performance and brain health software used in sports, clinical, and human-performance contexts. Comparable to Afin in applying computer-based visual stimuli to measure and train dynamic visual and cognitive performance.
• CogniFit: CogniFit offers cognitive assessment and brain-training software serving consumer, clinical, and professional markets. Comparable to Afin in delivering structured computerized cognitive/visual training programs with measurable outcomes.
• FitLight Sports: FitLight Sports provides light-based reaction and cognitive training systems used in professional sports and rehabilitation. Overlaps with Afin in reaction-speed and peripheral-vision training for athletes and clinical rehabilitation.

Broad incumbents

• Posit Science (BrainHQ): Posit Science's BrainHQ offers clinically validated cognitive training exercises widely deployed in healthcare and aging-population programs. Comparable to Afin's cognitive/rehabilitation use cases at a much larger scale, though it focuses on broader brain training rather than dynamic visual acuity.
• Nike SPARQ: Nike's SPARQ program included sensory and visual performance assessment/training for athletes. While discontinued as a standalone product, it represents the broad-incumbent approach to vision-and-reaction training that overlaps with Afin's sports vision proposition.

Emerging players

• Bynocs: Bynocs provides cloud-based vision therapy and visual performance software for clinics and optometrists. Comparable to Afin in commercializing software-based vision training, though targeted at clinical vision therapy rather than sports/industrial use cases.
• Viscando: Viscando is a Swedish company offering vision-based traffic safety and driver training analytics. Comparable to Afin in applying vision/cognition measurement to transportation safety, though geographically concentrated in Europe rather than Japan.
