IKUSHIMA GROUP

Welcome to the website of Ikushima Group!

Ikushima Group belongs to Department of Biomedical Engineering in Tokyo University of Agriculture and Technology. Based on physics and engineering, we conduct research and development of medical applications, industrial testing, and semiconductor devices.

FOCUS

ASEMtech, Inc. was established on November 1, 2023 to implement the technologies developed in our group.

Selected as one of the "ILS TOP 100 STARTUPS" as the top 100 most popular companies from major companies at #ILS2023, one of the largest open innovation events in Asia, which started on December 4.

Mr. Nobuto Kaido, a doctoral student, received the Encouragement Award at the Japanese Society of Ultrasound Medicine!
