A ramp installed over a drainage channel, alongside the pavement kerb, creating a slope that allows vehicles, motorcycles and carts to move from the road onto a driveway or pavement without having to negotiate a raised kerb.
The ramp features drainage holes and raised diamond-shaped patterns, known in Japanese as the "Fuji mountain pattern", designed to provide a non-slip surface.
