swinging door; double-action door
A door that can swing both ways, often used in kitchens or commercial spaces. The term is somewhat technical; in everyday conversation, スイングドア is also common.
The restaurant kitchen has a swinging door.
Compound of 自在 (jizai, 'freely moving') and 戸 (to, 'door'). The exact historical derivation is uncertain, but the term likely arose to describe doors that move freely in both directions.
