Nitchitsu

What Nitchitsu does

株式会社ニッチツ (Nitchitsu Co., Ltd.) is a Tokyo-headquartered, Tokyo Stock Exchange-listed (tyo:7021) Japanese industrial manufacturer founded in 1950, operating across four business segments: Machinery-Related, Resource-Related, Real Estate-Related, and Materials-Related. The Machinery-Related segment designs and manufactures ship hatch covers (ClassNK certified at the Matsura factory), ship hull blocks, marine outfitting products, large-scale plant equipment for power generation and steel mills (turbine casings, condensers, blast furnaces, electric-furnace structures, converters, steel ladles), rotary regenerative air preheaters sold under the company's own brand, and offshore-wind generation components; it also performs installation, maintenance, inspection, and modification work for thermal, wind, and nuclear power plants. Production is anchored by a 142,000 sqm Matsura factory site featuring a dedicated wharf for maritime shipment of oversized cargo, a 150-ton jib crane, a 2,000-ton press, NC plasma cutting, and integrated painting facilities, plus a complementary 84,000 sqm Emukae factory for ship hull-block steel processing.

The Resource-Related segment imports silica stone from India, China, and Sri Lanka and processes it through crushing, classification, chemical treatment, drying, heating, and magnetic separation to produce High Silica (HIS) brand purified silica powder at 99.6–99.9% purity, with grades (HIS, HQ/SQ, USHSH, OPTICAL, FILLER) serving semiconductor sealing, optical fiber, optical glass, CCD/CMOS cover glass, HDD glass substrates, and resin filler applications, as well as the NHP photocatalyst sub-line. The Materials-Related segment is executed through two wholly-owned subsidiaries: Tokyo Netsu Kagaku Kogyo K.K. (est. April 1966) produces the Thermajin heat-resistant coating line (room-temperature to 800°C performance, water-based sustainable formulations), and Sansen Kiko K.K. (est. February 1970) procures and processes Linatex high-purity, low-temperature-vulcanized natural rubber under a long-term R&D agreement with Linatex Rubber Products Bhd of Malaysia, applying it through proprietary lining-construction technology to proprietary industrial equipment including BK Hopper and OMK Mixer. The Real Estate-Related segment leases office space in the Akasaka, Tokyo headquarters asset.

Revenue is generated primarily through negotiated B2B manufacturing contracts with shipbuilders, power-plant operators, steel mills, semiconductor and electronics manufacturers, and HDD producers, supplemented by direct office-tenant leases and listed-product distribution via the Ipros industrial B2B platform; pricing is not publicly disclosed. The company operates exclusively inside Japan (manufacturing concentrated in Nagasaki Prefecture with sales reach across Kyushu, Kansai, and Kanto regions), is led by Representative Director Matsubara Yusei (松原 祐生), and discloses no external PE/strategic investor ownership.
