After graduating from Keio University, School of Medicine, I received training in the department of Radiology at Keio University. I took a medical degree (Ph.D.) from Keio University School of Medicine in 2013. During the past twenty years, my clinical and research activities have been focused on cryoablation, PAD treatment, coil embolization, AVM treatment, and lymphatic IR. Recently, my primary clinical interests are AVM treatment and lymphatic IR.
