Sendai Nikon Corporation (株式会社仙台ニコン, "Sendai Nikon") is a Japanese manufacturing company headquartered at 277 Aza-hara Tako, Natori, Miyagi 981-1221, Japan. It was established on June 29, 1971, with stated capital of ¥480 million. It is not publicly traded; it is a wholly-owned, consolidated manufacturing subsidiary of Nikon Corporation (Tokyo Stock Exchange: 7731), the optical and imaging group. Various Japanese corporate registries list headcount in the roughly 280–350 range; the City of Natori puts it at "about 300 employees." Sendai Nikon does not appear to publish its own revenue.
Operations. Sendai Nikon designs, prototypes and mass-produces products for the Nikon Group, and designs and builds production equipment. Its best-documented role is camera manufacturing: it has assembled digital SLR and mirrorless camera bodies (including the D4 and Z7 generations) and produces components such as shutter mechanisms in-house rather than buying them from third parties. CDP filings classify it under Nikon's Production Technology division (industrial machinery). A separate affiliate, Sendai Nikon Precision Corporation, handled stepper-related work and was merged with Zao Nikon in 2009.
Litigation posture. Sendai Nikon is an operating-company defendant, not an asserter. It has zero plaintiff cases and one defendant case in the tracked data, consistent with a manufacturing subsidiary being swept into suits against its parent. It has not been an active two-way litigant.
Notable case. In Intellectual Ventures I LLC et al. v. Nikon Corporation et al. (D. Del., 1:11-cv-01025), Intellectual Ventures I and II — an entity widely characterized as a patent assertion entity — sued Sendai Nikon alongside Nikon Corporation, Nikon Inc. and Nikon Americas over camera and image-sensor patents. The court granted Sendai's motion to dismiss for lack of personal jurisdiction in 2013 (935 F. Supp. 2d 787), holding that its Japan-based, parent-directed manufacturing and exclusive sales to Nikon Corporation did not establish Delaware jurisdiction. The case was terminated by stipulation of dismissal in May 2015. Sendai Nikon was also named as a defendant in separate 2017 suits filed by Carl Zeiss AG and ASML Netherlands B.V. against Nikon entities; those are outside the tracked case list.
