The development of electronics has given people great dreams and has turned those dreams into reality one by one. This development has been passed on to the 21st century, inspiring even greater dreams and hopes. I am deeply grateful and joyful to be engaged in a job that plays a part in this electronics industry. Moving forward, I will continue to serve as a conduit for the appropriate information on semiconductors and electronic components, so that I can contribute to the realization of humanity's great dreams and assist our clients in their product and information development. I sincerely hope to grow together with our clients in the information society of the 21st century. However, on the other hand, environmental issues have become a major focus. As a member of society, I feel the importance of leaving a rich natural environment for the future and preserving the fundamental values of humanity. I am committed to striving towards becoming a company that harmonizes with nature and society as we move towards an endless future.
