A journey into the world
that expands between
sleep and wakefulness

About us


We are conducting research using mice as a model organism to clarify the mechanism and function of sleep. Humans spend one third of their lives asleep. While we are asleep, we cannot protect ourselves from outside dangers. We can't study for tests. So why do we need such seemingly unproductive sleep that seems detrimental to our survival? Why do we need to let go of our consciousness on a regular basis? Our goal is to uncover the answer to this fundamental question: why do we sleep?
