Self-introduction
I specialize in sleep disorders such as sleep apnea and narcolepsy. Our Sleep Disorders Center aims to be the best facility for sleep medicine in Hiroshima Prefecture. And our center intends to provide world-class sleep treatments in collaboration with each department at Hiroshima Unversity Hospital. I hope that the Sleep Disorders Center will help patients suffering from sleep disorders in Hiroshima and neighboring prefectures.
