Hasegawa

Hasegawa is a prominent Japanese surname, written with the kanji characters 長谷川 (literally "long valley river"). The name originated from a place name: the Hase reading for 長谷 (a non-standard reading) is combined with the element 川 (kawa, meaning "river" or "stream"). It is one of the more common surnames in Japan, ranking among the top 20 most frequent in some surveys.

Etymology and Origin

The surname Hasegawa is distinctly Japanese in etymology, combining the placename Hase (referring to a specific location, often associated with the Hase-dera temples in Nara or Kamakura) with kawa for "river." This structure—a toponymic root plus a landscape element—is characteristic of many Japanese surnames. The use of the character 長谷 (long valley) rather than the more common phonetics mimics the geographic profile of a settlement spanning a valley with a river.
