Hamaguchi Urethane Co.,Ltd. is based in Nishiyama-cho, Chuo Ward, Hamamatsu City, Shizuoka Prefecture, and manufactures urethane parts and urethane foam products. Founded in April 1985, the company is exhibiting at RISCON TOKYO 2026 a urethane boat that does not sink even if it is punctured, together with a floating emergency product for placement on balconies and wooden decks.
The boat and the balcony product use hard urethane filled inside, forming an aggregate of foam. The company says the rescue boat is designed so that it will not sink even if it has a hole, and that the same urethane processing technology is applied to products intended to protect life during disasters and flooding.
In practical use, the rescue boats have been introduced to fire departments and municipalities across Japan, with about 400 to 500 boats deployed. The new balcony boat is intended for flood and inundation scenarios, allowing evacuation from a wooden deck or balcony and then floating up to help protect lives. Hamaguchi Urethane Co.,Ltd. develops and molds many urethane products for life protection and invites inquiries from interested customers.

00:00 We are Hamaguchi Urethane Co.,Ltd. from Hamamatsu City, Shizuoka Prefecture.
00:04 As the company name suggests, we manufacture urethane parts.
00:11 Representative examples include soft urethane parts such as armrests for Suzuki automobiles and guide bars at Disneyland.
00:18 Applying that technology, we are exhibiting a urethane boat that does not sink even if it has a hole, and
00:22 a product for placing on balconies and wooden decks that floats to protect lives.
00:30 Specifically, this has urethane inside, forming an aggregate of foam.
00:41 A familiar urethane material is the kind used for washing dishes, but this product uses hard rigid urethane.
00:50 During disasters and flooding, there may be sharp objects and environments where visibility underwater is poor,
00:58 so the rescue boat is designed not to sink even if it has a hole,
01:03 and about 400 to 500 of these boats have been introduced to fire departments and municipalities across Japan.
01:10 The balcony boat in the back is a new exhibit, and during flooding or inundation, if it floats then it can save lives,
01:21 so it is placed on a wooden deck or balcony and, in an emergency, people evacuate and it rises up to float with them, and that is the product we are exhibiting this time.
01:29 We develop and mold many products that protect lives with urethane, so please contact us if you are interested.
