Osaka Castle Residual Stone Memorial Park is a historic site located in Tonosho Town on Shodoshima Island, Kagawa Prefecture. The most striking feature of this park is the presence of massive stones that were originally intended to be used in the construction of Osaka Castle. These stones are laid out on stone-stacking foundations, allowing visitors to visually grasp the scale and texture of the sophisticated civil engineering techniques used during that era. Additionally, the site is registered as a "Michi-no-Eki" (Roadside Station), serving as a hub for both historical exploration and local tourism, complete with local specialty shops and rest areas.
The stones displayed here were meant for the reconstruction of Osaka Castle's stone walls during the Tokugawa era under the reigns of Shogun Hidetada and Iemitsu. This location, known as "Koumi," served as one of the stone-cutting sites for the castle. However, due to the conclusion of the warring era and shifting historical circumstances, the stones remained here on Shodoshima. Today, the site is maintained as a prefectural historical monument, serving as a vital cultural asset that preserves the history of Osaka Castle's construction.

Within the park, you can observe the massive stones arranged in their original intended layout. These stones possess a heavy, impressive texture with light beige and sand-colored hues. The park also features a museum that explains the methods of stone cutting and transportation used during the construction of Osaka Castle. The exhibits provide a deep understanding of the scale and technology of the time. Furthermore, you can find charming small items and souvenirs inspired by the stone motifs, reflecting the unique character of the area.
It is best to visit during daylight hours. Since the exhibits are primarily outdoors, the sunlight highlights the texture and depth of the stones, making for a more detailed observation. The park is accessible in all seasons, but on clear days, the contrast between the blue sky, lush greenery, and the beige stones creates a beautiful, refreshing atmosphere. A typical visit lasts about 60 minutes, making it a perfect spot to explore history before relaxing at the nearby rest areas.
Visitors can learn about the historical processes involved in building Osaka Castle. The museum offers visual and textual explanations of how stones were cut and transported, making history easy to understand. As a roadside station, the site also offers the chance to browse local specialties and unique souvenirs. It is an experiential spot where you can connect with the culture of Shodoshima while observing historical ruins.
As a "Michi-no-Eki," the park is surrounded by facilities that highlight the local culture. There are cafes, rest areas, and shops selling local specialties, making it an ideal place to take a break during your travels. The location also provides easy access to other sightseeing spots on Shodoshima, allowing you to plan a route that combines historical exploration with the island's natural beauty.
Since much of the park involves walking through outdoor exhibition areas, we recommend wearing comfortable walking shoes. As some areas lack shade, bringing a hat or parasol for sun protection is advisable. Please respect the historical site by avoiding excessive contact or any actions that might damage the stones or exhibits. For payments at the roadside station shops or cafes, both cash and credit cards are generally accepted. Please note that English-language support is limited, so using a translation app is recommended.
