Why do Married Couples in Japan sleep in Separate Beds? : What I learnt

I was frankly shocked to learn that Japanese couples sleeping in separate beds is actually quite common. Many of us assume that sharing a bed is a sign of a strong relationship, but in Japan, the perspective is different. Here is what I discovered about this unique practice, why it happens, and what it means for relationships.

A Tradition Rooted in History

In Japan, separate sleeping arrangements have been the norm for centuries.

Historically, homes were designed with small rooms and multipurpose living spaces. Instead of large, permanent beds, families used futons — thin, foldable mattresses laid on tatami mats. Every night, people would unroll their futons and sleep, then store them away in the morning.

This setup allowed each person to have their own sleeping area, and it wasn’t strange for married couples to sleep apart. Even today, this habit continues in many households, especially in more traditional families.

Better Sleep, Better Health

One of the biggest reasons couples sleep separately is comfort. I’ve learned that Japan values good sleep, and many believe that having individual sleeping spaces leads to better rest.
