[Online Exhibition 3/8-3/10] Invitation to Exhibit at the Future of Japanese Manufacturing Exhibition
From March 8 to 10, 2021, we will be exhibiting at the "Future of Japanese Manufacturing" exhibition. Once called a "manufacturing powerhouse," the Japanese manufacturing industry is now facing a crisis due to delays in digital transformation (DX) and other factors, bringing together technologies that will have a significant impact. Mr. Akira Ikegami and Mr. Wang, the chairman of HUAWEI, will also be speakers at the event. This is an opportunity to think together about the "future" of Japanese manufacturing! We look forward to your visit.
