The Daihatsu Costa was a playful, lightweight concept car debuted at the 2005 Tokyo Motor Show. Designed as a “breezy” beach or resort runabout, it drew inspiration from the structure of sandals and beach loungers.

The body was doorless and semi-open, featuring an open structure to emphasize a sense of freedom.

Its design theme was heavily influenced by casual footwear; the interior featured a flat, deck-like floor and "hammock" style seats covered in mesh.

Despite its fun appearance, it was equipped with an all-wheel-drive (4×4) system and had a ground clearance of 190 mm, making it surprisingly capable for light off-road or beach use.

Powered by a 660 cc (0.65L) 3-cylinder DOHC turbocharged engine.

The cabin was designed to be "hose-out," with all-weather materials that could withstand sand and water.

The Costa was often compared to a modern Japanese interpretation of the classic Mini Moke due to its minimalist, utility-focused design. While it generated interest for its unique "beach car" aesthetic, Daihatsu had no plans to move the vehicle into mass production.
