Yonago Castle once stood on a hill overlooking Yonago City in Tottori Prefecture. Although the castle buildings no longer survive, the ruins preserve impressive stone walls, foundation stones, and other features that reveal the structure of this important Japanese fortress. Historical documents and illustrated plans related to the castle have also been handed down in remarkably good condition. The site is designated a National Historic Site of Japan.
Today, the hilltop is a popular destination for walking and enjoying spectacular views. From the former main keep, visitors can look out over Mount Daisen, the Shimane Peninsula, Lake Nakaumi, and the city of Yonago. The combination of historical remains and expansive scenery makes Yonago Castle Ruins a rewarding stop for travelers exploring western Tottori Prefecture.
Yonago Castle, also known as Kume Castle or Minatoyama Castle, developed from fortifications established during Japan’s turbulent Sengoku period (approximately the 15th to late 16th centuries). The site eventually grew into a major castle complex that served as the administrative center of the Yonago Domain during the early Edo period (1603–1868). It later became a subsidiary castle of the Tottori Domain.
The castle’s history is associated with two names, Iinoyama and Minatoyama. In the medieval period, a fort occupied the summit of Iinoyama, south of present-day National Route 9. Its principal enclosure measured approximately 85 meters from north to south and 35 meters from east to west. Stone walls stood along the eastern and northern sides, and the fort had three gates. Although the site has since been leveled, traces of buildings were reportedly once visible there.
In 1591, Kikkawa Hiroie is said to have built a four-tiered keep at Yonago. In 1601, Nakamura Kazutada moved to Yonago as lord of Hoki Province and began further castle construction. He added a five-tiered main keep, creating a formidable fortress that became renowned as one of the finest castles in the San’in region of western Japan.
The early Edo-period castle was developed primarily on Minatoyama. Its main enclosure stood at the summit, with the second enclosure on the northern slope and the third enclosure below it. The earlier stronghold on Iinoyama was incorporated as an outer defensive position.
At its height, the castle complex included a main keep, a smaller four-tiered turret, approximately 30 additional turrets, and 20 gates. Moats surrounded the castle grounds and were supplied with seawater, strengthening the defenses while reflecting the site’s connection to the nearby waterways.
Following the end of the feudal era and the political changes of the Meiji period (1868–1912), the castle buildings were sold for a small sum. The structures disappeared, leaving the stone walls and other archaeological remains as the principal evidence of the former fortress.
In 1951, part of the site became incorporated into Minatoyama Park. On January 26, 2006, Yonago Castle Ruins were officially designated a National Historic Site, recognizing their importance in understanding Japanese castle history and the development of the region.
Although visitors will not find reconstructed keeps or surviving wooden buildings, the remaining stone walls and foundation stones offer valuable clues to the castle’s former appearance. By following the contours of the hill and examining the surviving masonry, visitors can imagine how the main enclosure, secondary enclosures, gates, turrets, and moats once worked together as a defensive system.
The remains also illustrate how the castle evolved from an earlier medieval stronghold into a more elaborate fortress during the early Edo period. For travelers interested in Japanese history and traditional castle architecture, the site provides an opportunity to explore a genuine historic landscape rather than a modern reconstruction.
One of the greatest attractions of Yonago Castle Ruins is the panoramic view from the summit. On clear days, Mount Daisen rises prominently in the distance, while Lake Nakaumi and the Shimane Peninsula stretch across the wider landscape. The urban streets of Yonago spread out below, creating a remarkable contrast between the city and the surrounding natural scenery.
The elevated viewpoint makes the ruins especially appealing to photographers and visitors who want to appreciate the geography of western Tottori Prefecture. Mountains, water, coastline, and cityscape can all be enjoyed from a single vantage point, giving the site its reputation as a place where the sky, mountains, sea, and town come together.
The castle hill is also a well-loved walking area for residents of Yonago. Exploring the paths and historic remains offers a pleasant way to enjoy the outdoors while learning about the city’s past. The changing scenery throughout the year adds to the appeal, whether visitors come primarily for the history, the views, or a quiet walk in nature.
Yonago Castle Ruins combine the remains of an important regional fortress with some of the finest panoramic views in the Yonago area. The surviving stonework reveals the scale and layout of the former castle, while the summit offers a sweeping perspective over Mount Daisen, Lake Nakaumi, the Shimane Peninsula, and the surrounding city.
For visitors exploring the Yonago, Mount Daisen, and Sakaiminato region, the ruins provide an engaging introduction to local history and landscape. Take time to explore the old defensive remains, imagine the castle at the height of its power, and enjoy the views that make this historic hilltop a memorable destination.
