MONARTE Floating Floor 2026: how Japan's floating flood-proof parking platform works
MONARTE Floating Floor is a buoyant parking platform from Japan that rises with a parked vehicle during flooding and is rated for loads up to 3000 kg.
Japan has proposed an unusual way to save a car from a sudden flood — make the entire parking space float instead of the vehicle itself. The MONARTE Floating Floor normally serves as a parking platform, but when the water rises it begins to float together with the car. The published specification is rated for loads of up to 3000 kg.
The 2580 × 6100 × 280 mm platform is built around a foamed core with a protective polyurea coating. It does not need separate flotation bags, a mechanical lift or an electric drive to rise: the floor structure itself provides the required buoyancy. Steel anti-drift posts are used to limit movement during flooding.
The Floating Floor was first shown publicly in January at Tokyo Auto Salon 2026. At the time, the developer also demonstrated a test with a relatively heavy electric van: the platform floated without noticeable sagging and remained stable.
Interest in the design has increased again amid heavy rain in Japan. On September 8, severe flooding in Nagoya inundated roads and caused major disruptions to public transport. MONARTE itself warns that the system's effectiveness depends on flood depth, current strength, the risk of impacts from floating debris and other conditions, so each installation must be configured for the specific site and vehicle.
The system is being developed by Tajima Motor Corporation. No fixed public price has been announced for the Floating Floor: the company calculates the cost and installation parameters individually, taking into account the vehicle's weight and dimensions, expected water depth, current and the conditions of the specific parking site.
