The Meji umbrella stand is a silicone-covered resin block with a cross shape cut into its top.
"The design's motif takes inspiration from the joints of a tiled floor," said Nendo. "When an umbrella is set into the grooves, the product becomes an umbrella stand."
Users press the spike of their umbrella into the centre until it is held vertically in place.
The studio, led by designer Oki Sato, wanted to reduce the space taken up by traditional umbrella stands.
"Typical umbrella stands look like either a huge container or a box full of holes, and can't help but seem out of place when not holding any umbrellas," said Nendo, which also recently launched a cube of different-sized sticky notes.
"By using grooves instead of holes, this umbrella stand maintains a simple, clean appearance," it added.
The product is available as an individual cube for single use, or as a longer version that can hold a trio at once. Both come in five colours, including black, white and a light purple-grey shade.
Nendo created the objects for its by|n homeware range, available from Japan's Seibu department stores.
Meji is not necessary for another of Nendo's umbrella designs, which has a two-pronged base that allows it to stand on its own when not in use.
The studio has also created folding umbrella with a cover tucked into its handle, among a spate of accessories that include cone-shaped stackable slippers and a range of flexible polycarbonate reading glasses.
