The roji acts as a transitional space leading from the entry gate to the teahouse, and generally cultivates an air of simplicity and purification.
[7] Typical features include the tsukubai (ablution basin), tōrō (lantern), tobi ishi (stepping stones), and wicket gate.
[15] Sadler argues that the roji, with its small size, harmonious proportions, and 'simple suggestiveness' served as a model for domestic Japanese courtyard gardens.
Additionally, tōrō, originally used to light the path for ceremonies held at night, were soon adopted as decorations for other types of gardens, a practice that continues.
[17] In the works of Japanese writer Nakagami Kenji, roji, in the sense of "alley", can also be understood as a euphemism for the buraku ghettos, where burakumin people used to live.
