We will host the joint meeting of “Stroke 2021” in Fukuoka on March 11-13, 2021. Stroke 2021 consists of annual meetings of 3 societies, including Japan Stroke Society, Japanese Society on Surgery for Cerebral Stroke, and SPASM Symposium. Of these, I will host the 50th. annual meeting of Japanese Society on Surgery for Cerebral Stroke. We strongly hope that we can advance the diagnosis and treatment for patients with stroke altogether.
