Nakakita Seisakusho

What Nakakita Seisakusho does

Nakakita Seisakusho Co., Ltd. (株式会社中北製作所) is a Japanese specialist manufacturer of fluid control devices, founded in 1930 and formally incorporated on May 11, 1937. The company is listed on the Tokyo Stock Exchange Standard Market under ticker 6496 (TYO:6496 / 6496.T) following its 1971 IPO on the Osaka Securities Exchange, and it is headquartered at 1-1 Fukuno Minami-machi, Daito City, Osaka Prefecture, with 251–500 employees.

Its core product portfolio centers on automatic control valves (自動調節弁), butterfly valves (バタフライ弁), and marine remote control devices (遠隔操作装置), with a specialized cryogenic valve line for liquefied hydrogen, LNG, and methanol marine fuel systems. The technology stack rests on precision mechanical engineering and decades of qualification for harsh marine environments, including IMO-aligned safety standards and remote actuation systems for ship automation — capabilities demonstrated by a March 2026 contract with Kawasaki Heavy Industries for low-temperature valves on 40,000 m³ class liquefied hydrogen transport vessels.

The business model is direct B2B sales to shipbuilders and industrial process operators in Japan and the broader Asia-Pacific region, with project-based pricing that is not publicly disclosed. Revenue is generated through one-off equipment sales integrated into new vessels and industrial plants rather than recurring subscriptions. FY2025 (99th period, year ending May 31, 2025) net sales were ¥23,768 million with order intake of ¥29,445 million, an ROE of 6.8%, and net profit of ¥1,730 million — figures that highlight accelerating forward demand driven by maritime decarbonization and the emerging hydrogen transport segment.
