In modern times it often means an outside area at a cafe or tearoom.
In Japanese gardening, a roji is a particular style of relatively small garden, originally developed for the entry gardens to Japanese teahouses, intended to set the mood of guests arriving for the Japanese tea ceremony.
[2] These are designed almost exclusively to be seen from the path leading through them to the building, and tea would not normally be consumed in them.
The style is suitable for smaller front gardens of houses, and has often been used for these, both in Japan and the West.
The term may sometimes be used for a herb garden specializing in herbs that are consumed as tea, such as chamomile, bee balm, peppermint, lemon balm, and lavender.
