Totaku Industries

What Totaku Industries does

Totaku Industries, now operating as Nagase RooTac Industries (ナガセルータック株式会社) following a November 2025 rebranding, is a Japan-based manufacturer of industrial hoses, electrical construction materials, civil engineering materials, and bridge-related materials. Founded in 1952 and headquartered in Osaka with 251–500 employees, the company sells through direct sales offices located throughout Japan and through its corporate website, which offers an online hose search system, downloadable technical drawings, catalogs, product videos, and web-based consultation services. The product portfolio is organized into four core categories: industrial hoses, electrical materials, civil engineering materials, and bridge-related materials, with proprietary offerings such as the Square TAC Rex (角型TACレックス) product line.

The company's underlying technology is industrial hose and material manufacturing for demanding applications, including data center cooling, electrical installation, civil construction, and bridge infrastructure. Digital tooling (hose search by size and physical properties, technical documentation such as the Non-applicability Judgment List, video tutorials) supplements the physical product catalog. All manufacturing facilities have transitioned to substantially 100% renewable electricity, reflecting an environmental commitment disclosed prominently on the company site.

Revenue is generated through B2B hardware sales of these four product categories, with pricing conducted via quote-based inquiry rather than published list prices. Customers span multiple verticals — industrial manufacturing, electrical contractors, civil engineering contractors, bridge infrastructure, and data center operators — with data center infrastructure positioned as a targeted growth vertical. The company is a subsidiary of NAGASE Group (長瀬産業), a major Japanese trading company listed on the Tokyo Stock Exchange, providing parent-level supply chain and financial backing. In 2026, the company has navigated raw material cost pressures stemming from Middle East supply disruption with two rounds of price revisions (April and June 2026), opened a new Okinawa Factory in March 2026, and expanded marketing efforts including participation in JECA FAIR 2026.
