Osaka Castle Zanseki Memorial Park, located in Tonosho Town on Shodoshima Island, Kagawa Prefecture, is a park dedicated to preserving significant historical remains. The most striking feature of this site is the presence of massive stones that were originally intended to be used in the reconstruction of Osaka Castle. These stones are laid out upon stone foundations, allowing visitors to visually grasp the scale and texture of the massive civil engineering techniques used during that era. Additionally, the site functions as a 'Michi-no-Eki' (Roadside Station), serving as a local hub where you can enjoy historical exhibits alongside local specialty products and comfortable rest areas.
The stones displayed in this park were originally meant for the stone walls of Osaka Castle, which was rebuilt during the Tokugawa era by Hidetada and Iemitsu. This specific area, known as 'Koumi,' served as one of the stone-cutting sites for the castle's construction. Although the stones were prepared for transport, the shifting tides of history and the conclusion of the warring eras meant they were left behind in Shodoshima. Today, the site is a designated historical monument of the prefecture, serving as an important cultural asset that preserves the history of Osaka Castle's construction.

Inside the park, you can observe the massive stones arranged in their original intended layout. These stones possess a heavy, impressive presence with textures of light beige and sand colors. The park also features a museum that provides detailed explanations of how these stones were cut and transported during the construction of Osaka Castle. The exhibits are designed to help visitors understand the scale of the stones and the advanced technology of the time, providing a deep sense of historical immersion. Furthermore, you can find and purchase 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 park focuses on outdoor displays, visiting when the sun is out helps highlight the texture and indentations of the stones, allowing for a more detailed observation. The park is accessible in any season, but on clear days, the contrast between the blue sky, lush greenery, and the beige tones of the stones creates a beautiful, open atmosphere for a stroll. A typical visit takes about 60 minutes, after which you can relax in the provided rest areas.
Visitors can learn about the historical processes related to the construction of Osaka Castle. The museum displays materials regarding the cutting and transportation methods of the time, providing a visual understanding of history. As a roadside station, the area also allows you to browse local specialties and unique souvenirs inspired by the stones. It is a place where you can experience the culture of Shodoshima while observing historical ruins.
As a 'Michi-no-Eki,' the park is surrounded by facilities that highlight the local region. There are cafes, rest areas, and shops selling local specialties, making it an ideal spot to take a break during your sightseeing. The park also offers good access to other tourist spots on Shodoshima, allowing you to plan a route that combines historical exploration with the island's natural beauty. The surrounding area is rich with the unique food culture and scenic landscapes of Shodoshima.
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 sun protection is advisable. Please respect the site by avoiding excessive contact with or damage to the historical stones and exhibits. For purchases at the roadside station or cafe, both cash and credit cards are generally accepted.
