Unsinkable urethane boat - Hamaguchi Urethane [RISCON TOKYO 2026]

October 26, 2026

At RISCON TOKYO 2026, Hamaguchi Urethane Co.,Ltd. introduced a urethane boat that will not sink even if it develops a hole, along with a veranda boat designed to be placed on a balcony or wooden deck. Headquartered in Hamamatsu, Shizuoka Prefecture, the company is a specialist manufacturer handling urethane product molding, forming and processing, and it also accommodates small-lot, multi-item production and products with complex shapes. The exhibit applied technologies cultivated through the production of soft parts such as armrests for Suzuki automobiles.
The displayed boat is characterized by a structure in which hard urethane is filled inside, preserving buoyancy through an aggregate of bubbles. Assuming disaster and flood conditions in which sharp objects are common and underwater conditions are difficult to see, the company promoted it as a rescue boat that is unlikely to sink even if punctured. It also said the product has been introduced by fire departments and municipalities across Japan.
The other veranda boat is a new product intended for flood and inundation damage: under normal circumstances it is placed on a wooden deck or veranda, and in an emergency it is meant to be used for evacuation and then float up. The company said it has developed and molded many urethane products that protect lives, and invited interested visitors to contact it.
