Irori (いろり, 囲炉裏, 居炉裏) are a type of traditional sunken hearth common in Japan. Used for heating the home and cooking food, irori are essentially square pits in the floor with a pot hook, or jizaikagi (自在鉤). These hooks generally were hollow bamboo tubes containing an iron rod, with an attached lever, often shaped like a fish, that would allow the pot or kettle to be raised or lowered.
