History
The Onago Battery was one of several coastal artillery fortifications built as part of a defensive network along the Sea of Japan. Constructed in response to the increasing presence of Western ships, it held several large cannon emplacements. The name “Onago” or “Women’s Battery” is said to originate from local accounts that women of the town played a significant role in its construction while the men were away fighting in other battles.
