In 1923, an earthquake with a magnitude of 9 struck Tokyo and Yokohama. A huge area of Tokyo burned. But, Ueno Park, protected by the water of Shinobazu pond, survived unscathed, as did many of the people from around Tokyo who sought refuge there. Emperor Hirohito visited the park and its new homeless residents soon after, and presented it as a gift to the people of the city, renaming it UenoImperial Gift Park.
