Furukawa is a Japanese surname meaning "old river." It is composed of the characters 古 (furu, meaning "old") and 川 (kawa, meaning "river") or 河 (kawa, also meaning "river or stream").

Etymology and Origin

Furukawa (written in kanji as 古川) is a toponymic surname, deriving from a local landmark — an ancient or old river. In Japanese onomastics, surnames frequently originated from elements of the natural landscape such as mountains, valleys, and rivers. The use of kawa (river) is widespread in Japan, appearing in other common surnames like Kawada ("rice paddy river") and Kawaguchi ("river mouth").

According to the 2010 United States Census, Furukawa ranked as the 24,531st most common surname in the United States, with approximately 1,019 individuals bearing the name. Census data further shows that Furukawa is most prevalent among Asian/Pacific Islander descent (79.0%), reflecting Japanese American immigration patterns. Moreover, the name also gained a presence in Portuguese-speaking countries, such as Brazil, due to Japanese diaspora during the early 20th century.
