A new craze is taking Japan by storm and sees adults wrapped up like babies and swayed from side-to-side.
The bizarre-looking therapy called Otonamaki is becoming popular especially with new mums.
At a recent session in Tokyo organised by a non-profit organisation dedicated to post-natal women, five tried out the new trend.
Each took turns to tie each other in a large cloth from head to toe and in a cross-legged position.
They also swayed lightly from side-to-side after being laid gently on their backs in the hope of helping loosening the muscles and bones.
Some were given the option to use a colored cloth to help simulate different environments as they lay completely covered in the white cloths.
After emerging one woman said: “It felt warm and there was this feeling with my body. I have never experienced this before so its quite hard to describe properly.”
