YTD as of 2026-07-10 · source: Yahoo Finance
The Japanese leader with ~35% global share in RV precision reducers for articulated-robot joints, one of the two pillars of robot reducers with Harmonic Drive. The thesis is humanoids — 28% share in miniature RV for humanoids captures new demand, and it is doubling RV capacity by 2026 to meet it. The risk is that this demand is tied to the ramp pace of robot OEMs (FANUC, Yaskawa, Tesla Optimus) with high volatility, and in graph terms it is a component bottleneck sitting below the OEMs, where reducer capacity is the ceiling on robot production.
