Overview (history, characteristics, attractions)
Kaikoen is a castle park in Komoro City, Nagano Prefecture, and is a historical park built on the site of the former Komoro Castle (Komoro Castle Ruins). Remains of the castle's stone walls, earthworks, and main citadel remain within the park, and its greatest appeal is the way the charm of the castle coexists with the natural scenery of the four seasons, including cherry blossoms, azaleas, and autumn leaves. Although it is located close to the city center, it is dotted with attractions such as quiet walking paths, Japanese gardens, and Kaiko Shrine, and is popular among locals as a spot where you can experience literature (the scenery is known from Shimazaki Toson's poem "Komoro Naru...") and local history.
Highlights
- Stone walls and moat remains: The stone walls and dry moats that give a glimpse into the castle's former structure have been well preserved and are a popular photo spot.
- Nostalgia Shrine: You can enjoy worshiping at the shrine within the grounds and the atmosphere of the old buildings.
- Garden, pond and promenade: The garden has a Japanese garden-style landscape and a promenade around the pond, making it perfect for a leisurely stroll.
- Cherry blossoms (spring) and autumn leaves (autumn): The cherry blossoms bloom in spring, and the fiery autumn leaves are beautiful in autumn, so the park is bustling with visitors during the season.
- View from the castle ruins: From the high ground within the park, you can see the city and surrounding mountains, and enjoy different views depending on the season.
