Investment Thesis
Japan's leading optical sensor manufacturer. Photomultiplier tubes, image sensors, photodiodes for robot vision, semiconductor inspection, medical imaging, LiDAR. FY2026 guidance: ¥222B rev (+4.7%), ¥17.2B OP (+6.4%). Active ¥13B share buyback. 3D Machine Vision market USD 8.1B→USD 22.4B by 2032. Monopoly-like positions in niche photonics.
Risk
1) GPT FINDING: high-quality technology company but only indirect robotics beneficiary. 2) Named semicap/machine-vision OEM customers not publicly confirmed. 3) MEDIUM is highest sensible conviction, only if you want broader photonics exposure.
Monitoring Trigger
Semiconductor inspection order acceleration. Named robot vision OEM partnerships. ROE >6% → upgrade. PE >50x → TRIM.
