Title: Hiroyuki Sasakawa and a Comprehensive Disaster-Resistant Building Concept.

Introduction

Hiroyuki Sasakawa is an inventor based in Tokyo, Japan, associated with Tsm Corporation. His work includes a building concept that combines flood resilience, seismic isolation, fire-prevention water storage, and water conservation.

Latest Patents

Sasakawa is credited with 1 patent: “Floating Type Comprehensive Disaster Prevention Water-Saving Building Structure with Water Damage Resistance.” The invention describes a building that can float by using a lower-level water reservoir as a buoyancy tank when severe flooding is expected. Its movable section incorporates seismic isolation when raised, while stored rainwater can help lower the building’s center of gravity, provide water for firefighting, and reduce reliance on conventional water supplies.

The concept also proposes using rainwater to cool rooftops and exterior walls through evaporation. A wall-mounted water tank can serve as a detachable lifeboat to support the transport of multiple people during rescue operations. The described features can be selected and installed as needed.

Career Highlights

Sasakawa’s patent brings together several disaster-prevention and sustainability functions in a single building concept. Its proposed features address flooding, earthquakes, fire preparedness, rainwater use, and emergency evacuation.
