context_page_description: Kōchi Castle is a castle located in Kōchi, Kōchi Prefecture, Japan.
context_section_description: Two previous attempts were made to build castles on Otakasa Hill. Both failed. The first attempt was by Otakasa Matsuomaru sometime during the late Heian or Kamakura periods. The second was in 1588 by the conqueror of Shikoku, Chōsokabe Motochika. The area around the hill at this time was extremely swampy, due to the influx of alluvial sediments from the Kagami River. Consequently, previous builders were never successful in establishing a permanent fortress on the site where Kōchi Castle stands today.
