Named in memory of Kiyohira Fujiwara (1056–1128), founder of the Fujiwara clan in the northern part of Japan. He built a castle in Esashi {see planet  (9368)}, near Mizusawa {see planet  (7530)}, and accumulated the means to reign over the wider area. He then moved to Hiraizumi, about 30 km south of Esashi, which rapidly became one of the most prosperous independent realms in Japan during the eleventh and twelfth centuries. Unburnt temples and remains tell us that the cultural level of the realm was comparable with that of Kyoto {see planet  (4352)}. (M 34626) _ _.
