Kōfu, Yamanashi
Yamatokōriyama has been twinned with Kōfu, Yamanashi, in Japan since 1992. The two cities are twinned because during the Edo period the Yanagisawa family were transferred from Kofu to Yamatokoriyama under Kunigae (国替), a policy in which "daimyōs" were transferred from one post to the next.
