What Is Gravel?
Gravel refers to small round stone aggregates commonly used in gardens and landscaping for decorative purposes.
It is often employed alongside garden stones, tiles, and bricks to enhance garden aesthetics. The sound produced when walking on gravel also serves as a security measure, deterring suspicious individuals from entering the property.
The size of individual stones is categorized according to traditional Japanese dimensions, such as 7 rin (2-3 mm), 3 bun (7-9 mm), and 5 sun (12-17 mm), with sizes smaller than 7 rin classified as “gravel.”
In recent years, the variety of gravel options has expanded beyond traditional white and black cobble gravel to include colorful decorative gravel suitable for Western-style gardens, catering to diverse garden tastes.
