Grinding Technology Japan 2023 has ended successfully. We would like to express our sincere gratitude to all the exhibitors, visitors,and all those who cooperated with us.
This year, the third edition of the exhibition, we were able to hold the event in a more normal way as the restrictions of Covid-19 arebeing eased. The lively venue made for a lively business meeting. The exhibition hall was filled with a variety of grinding machines,
including surface, cylindrical, internal, and tool grinders, as well as grinding wheels, measuring instruments, and peripheral equipment.
Many companies from Europe, China, Korea, Southeast Asia, and other countries also exhibited their products and technologies
related to grinding and tool manufacturing.
Cutting Forum 21, which participated as a special supporting organization, held machining demonstrations by its member companies
in the exhibition hall, which attracted a great deal of interest from the audience. Advanced Technology Fair 2023 (ATF 2023) was heldon the second day of the exhibition by The Japan Society for Abrasive Technology; special cooperating organization. In addition,a poster exhibition was held throughout the exhibition period to showcase the research of various laboratories, promoting activeexchanges between universities and the private sector.
A seminar on the latest technologies related to the exhibition was also held, attracting a large number of participants. The "Grinding
Concierge," which has been popular since the first exhibition, was held again this year, and grinding experts were on hand to offer
technical advice.
Grinding Technology Japan (GTJ), an exhibition specializing in tool manufacturing technology and grinding process technology,
will continue to maintain its characteristics and aim for steady growth in the future. We hope to see all related parties at GrindingTechnology Japan (GTJ) 2025 (scheduled to be held at Makuhari Messe in the spring of 2025) in two years' time.

Abrasive processing that travels through time and space
Dr. Junichi Ikeno／Chairman, The Japan Society of Abrasive Technology
Every day, we conduct research and development aiming for cutting-edge technologies. This is a very respectable activity foran engineer, but sometimes Dr. Ikeno wonder if he is forgetting that abrasive processing is the oldest technology known to
mankind and that we should learn from the wisdom of our predecessors and nature. Here Dr. Ikeno focused on the study ofnatural whetstones from the viewpoint of the history of technology.  In addition, he presented transfer engineering casestudies related to abrasive processing.

The Japan Society for Abrasive Technology Exhibition Corner
The Japan Society for Abrasive Technology was founded in 1957 by the Abrasive Grain Processing
Society of Japan and the Kansai Abrasive Grain Processing Society of Japan, and became a corporationin 1995. And in 2009, we were recognized as a public interest incorporated association. During
this period, we have consistently developed as a society that comprehensively covers practicalmanufacturing technologies such as abrasive grain processing technology, tool technology,
machining machinery, and measurement technology, and as a society that is "useful" and "fun" toparticipate in.
This year's event featured exhibits from laboratories in a wide range of fields, including the latest
grinding technology, grinding tool measurement and evaluation technology, laser processingtechnology, ultra-precision and micro-machining technology, and environmentally conscious
processing technology.
