Greetings from the Representative Director

FROM DECOMMISSIONING TO SPACE

From Nuclear Decommissioning to Space

At Yoshida, we’re always looking for new challenges and ways to grow. Since our founding in 1923, we’ve built over 100 years of experience and history. In 1961, we became the first company in Japan to design and manufacture gloveboxes, marking our entry into the nuclear industry. Our strength lies in our in-house integrated production system, where design, fabrication/welding, and machining departments work closely together. This allows us to create products that fully meet our customers’ needs. In recent years, we have been actively engaged in research and development, collaborating with universities, research institutions, and venture companies on a variety of projects. These include the development of next-generation gloveboxes with remote operation capabilities and the verification of separation methods for organic solvents used at the Fukushima Daiichi Nuclear Power Plant. We are also exploring new ways to apply our proprietary technologies, such as adapting the shielding and containment techniques developed during the Fukushima decommissioning work for use in fields like medicine and aerospace. We strive to be the company our customers turn to when they face challenges, and we will continue to build a system that enables us to fully realize their requirements. Thank you for your continued support.

Representative Director

Shusuke Yonekawa
