TSUNE SEIKI

What TSUNE SEIKI does

TSUNE SEIKI (津根精機株式会社) is a Japanese industrial machinery manufacturer founded in 1917 and headquartered in Toyama City, Toyama Prefecture, specializing in metal cutting solutions. The company designs and produces a comprehensive portfolio of circular saw cutting machines, band saw machines, hacksaw machines, pipe/roll cutter machines (including laser pipe cutting via TLX70PL), double-end chamfering machines, saw blade grinding machines, and mist lubrication systems, alongside a full line of saw blades (carbide-tipped, HSS, solid carbide, band, segmental) and custom carbide special tools. Its distinguishing technical claim is being the world's only manufacturer that independently develops both cutting machines and cutting tools in-house, supported by proprietary T3 coating technology (~3,200 Hmv hardness, 1,100°C oxidation resistance) and integrated production line equipment proposals that combine cutting machines, conveyors, and chamfering equipment from a single supplier.

The company operates a vertically integrated group structure. Wholly-owned subsidiary 津根マシンツール (Tsune Machine Tool Co., Ltd., 42 employees, capital ¥10M) handles all domestic sales and after-sales service through 9 regional offices across Japan (Kanto, Kansai, Chubu, Kyushu, Shizuoka, Takasaki, Hiroshima, Toyama). TSM Corporation (65 employees, capital ¥80M, renamed from Tsune Wagner Carbide in January 2024) specializes in circular saw blade development, design, manufacturing, and resharpening. International sales are executed through Tsune America LLC (Edinburgh, Indiana), Tsune Europa GmbH (Alsdorf, Germany, established 2015), and Tsune Seiki (Thailand). Revenue is generated through direct B2B hardware sales of capital equipment and consumable tooling, complemented by after-sales maintenance and repair services.

The business model is enterprise field sales targeting manufacturing customers across automotive, construction, machinery, and general metal processing sectors. Customer acquisition relies on participation in major trade shows (JIMTOF, MEX Kanazawa, IMTS, EMO Hannover, FABTECH, AMB Stuttgart, ALUMINIUM), supplemented by YouTube product demonstration content and Instagram recruitment marketing. The company remains privately held, family-owned, and self-funded, with no external institutional investors, public listing, or disclosed revenue. As of 2026, the company continues to operate, with a near-term TJ100GL II product launch scheduled for MEX Kanazawa 2026 and a minor non-impactful fire incident at the Juchu factory in May 2025.
