Message from the president

Nastoa Co., Ltd. was established in 1948 as Toa Seiki Co., Ltd., the predecessor of Nastoa Co., Ltd., following the merger of Fuji Zoki and Hinomaru Seiki Seisakusho, both of which were under the umbrella of Japan Metallurgical Industry Co., Ltd. At the time of its establishment, the company was the only manufacturer in Japan capable of producing machinery for every stage of match manufacturing.
Since beginning the production of stainless steel pipes in 1954, we have
developed our business over many decades as a specialized manufacturer of
stainless steel welded pipes. Today, as a member of the Japan Metallurgical
Industry Co., Ltd. Group, a manufacturer of stainless and specialty steels,
we manufacture and sell welded pipes made not only from stainless steels,
including duplex and super-austenitic grades, but also from
high-performance materials, primarily high-nickel alloys.

Drawing on our long-standing expertise and proven track record in stainless
steel welded pipe manufacturing, we provide high-quality products that meet
the diverse needs of our customers across a wide range of industries and
facilities. Our products are used in power generation facilities, LNG
carriers, LPG and ammonia carriers, LNG storage facilities,
hydrogen-related facilities, semiconductor manufacturing plants,
pharmaceutical plants, and various other industrial plants.

Looking ahead, we will continue to contribute to the advancement of society
by delivering trusted quality backed by our extensive track record and
accumulated technological expertise. At the same time, we will strive to
grow together with all of our stakeholders and remain a company that earns
their trust and contributes to a sustainable future.
