Aiki Castle (Minochi)


NaganoAikijou (1).JPG


Aiki Castle was built by the Aiki Clan; it was the castle of Aiki Ichibē Masatomo, also known as Aiki Masāki, who was originally a vassal of the Ôi Clan of Saku. Takeda Shingen ordered Aiki to build the castle for use during the Kawanakajima Campaign. Aiki Village was split between north and south in the Sengoku Period and Aikijō was built in the north (Aiki presumably took his name from this area). Aiki fought for Takeda Shingen in the Fourth Battle of Kawanakajima in 1561. Aiki Masāki died at the castle in 1567, leaving two successors, Yorifusa and Nobufusa. Nobufusa died at the Siege of Takatenjinjō in 1581.

Visit Notes

The earthly remains of Aikijō / Ainokijō consist of lonely clump of piled earth in the corner of a girls' school. Probably this was part of a segment of dorui (earth-piled ramparts). There is a small shrine and a marker for the castle on top. I came here because I had some time to kill in Nagano City.

  • Note on reading: if "Ainoki" then the "no" is unwritten or rendered ノ, the possessive particle.
