Message from the president

NAS TOA Co.,LTD. traces its origins back to 1948, when Fuji Zoki and Hinomaru Seiki Seisakusho—both affiliated with Nippon Yakin Kogyo Co., Ltd.—merged to form Toa Seiki Co., Ltd., the only manufacturer in Japan capable of producing the entire range of machinery required for match production.
In 1954, we began manufacturing stainless steel pipes and have since developed into a dedicated producer of welded stainless steel tubing. As a member of the Nippon Yakin Kogyo Group—a leading manufacturer of stainless and specialty steels—we now focus on the manufacture and sale of welded pipes made from stainless steel (including duplex and super-austenitic grades) as well as high-performance alloys, particularly high-nickel alloys.
Leveraging our long history and expertise in welded stainless steel pipe manufacturing, we serve a wide range of industrial sectors, including power generation facilities, LNG carriers, LPG/ammonia carriers, LNG storage systems, hydrogen-related equipment, semiconductor plants, and pharmaceutical factories. We pride ourselves on meeting diverse customer needs with high-quality products.
At the heart of NAS TOA’s expertise lies the technology of metal-to-metal bonding. Through our commitment to “connecting materials, connecting people,” we strive to contribute to the realization of a carbon-neutral society.
