Tenryu Seiki Co., Ltd.

Tenryu Seiki Co., Ltd. (天竜精機株式会社) is a Japanese engineering company based in Komagane, Nagano Prefecture, that designs and manufactures dedicated and custom-built automation machines for manufacturing and factory environments. Its work spans the supply, processing, assembly, inspection, packing and material-handling stages of production, and the company describes itself as a group of engineers that takes a "front-loading" approach to manufacturing — engaging deeply at the hearing and specification stage and carrying projects through design, delivery and maintenance. The company's core offering is organized around what it calls the Automation Lifecycle Service, branded "ALiS™", which covers the full cycle from customer consultation and design through delivery and after-sales maintenance. Its product range includes dedicated automatic machines and custom solder printing machines, and it positions itself as offering best-fit solutions matched to each customer's production environment, drawing on experience across many industrial fields. Tenryu Seiki is also active in developing its own branded equipment. It has launched products such as the TSP-770 cream solder printer and a rheology analyzer, the PRA-100, and in 2023 began shipping what it describes as a world-smallest-class cream solder printer. More recently it has pursued collaborative automation, co-developing the "AutoTaylor System" with RoboCross and exhibiting at events such as DXPO Nagoya. The company also engages in community and educational activities, including parent-and-child factory tours and workplace experience programs for local students. As a privately held Japanese manufacturer, Tenryu Seiki serves industrial customers rather than consumers, and its public communications emphasize engineering capability, customization and lifecycle support. Its headquarters location in Komagane places it within Nagano Prefecture's precision-machinery and electronics manufacturing cluster.

Tenryu Seiki Co., Ltd. is a Japanese engineering company located in Komagane, Nagano Prefecture. Public information about its earliest years is limited, but its corporate communications describe a business built around designing and manufacturing dedicated and custom-built automatic machines for manufacturing and factory operations, covering the supply, processing, assembly, inspection, packing and material-handling stages of production. The company's stated philosophy is "front-loading manufacturing" (フロントローディングのものづくり), in which engineers take the lead from the initial customer hearing through design, delivery and maintenance. This approach is packaged commercially as the Automation Lifecycle Service, branded "ALiS™", which the company presents as an end-to-end service for solving manufacturing customers' problems. Over time Tenryu Seiki has expanded from custom machinery into its own branded products. In May 2016 it launched the PRA-100 rheology analyzer as a new product. In July 2016 it opened the Tenryu Mirai Creation Center (天竜未来創造センター), a facility announced as a press release. In October 2022 it introduced the TSP-770 cream solder printer, and in June 2023 it began shipping what it describes as a world-smallest-class cream solder printer. More recently the company has moved into collaborative automation. It co-developed the "AutoTaylor System" with RoboCross, announced its first exhibition of the system in May 2026, and reported exhibition results in June 2026. It has also exhibited at DXPO Nagoya, with its participation covered by the Chunichi BIZ Navi publication. Alongside its industrial activities, Tenryu Seiki engages with its local community through parent-and-child factory tours and workplace experience programs for junior high school students, and it maintains a company blog and recruitment activities for new and mid-career hires.
