Greetings

Yoshida’s story begins back in 1923 and has a history of almost 100 years till today.
Since 1961, our company has been expanding our business by designing and manufacturing welding equipment for nuclear energy field such as glove boxes. Most notably, as a result of responding to various orders from custom-made products for R&D to mass-produced products, our organization has achieved high efficiency by forming a integrated three divisions: designing, machining, and welding.
Our second factory has opened on June 30, 2018, and it features five-sided processing machines (3.6m x 8m x 1.7m). From now, we move forward to focus on large-scale welding and large-scale machining products, and manufacture oxygen-free and moisture-free glove boxes by developing Yoshida’s core isolation technology, cultivated over many years.
We look forward to your continued guidance and encouragement.
