 Karesansui are commonly referred to as Zen Gardens outside of Japan, but that name was assigned by those foreign to Japan.In 1974, a plaque contrived by artist, Ruth Asawa was gifted to the garden in honor of Makoto Hagiwara and his family for their dedication to the garden's beginnings and expansion.The San Francisco Recreation & Park Department, which has maintained the garden since 1942, named the road bordering the garden Hagiwara Tea Garden Drive in 1986 to further honor the garden's original benefactors.
