What Are the Takamatsu Castle Ruins (Tamamo Park)?

The Takamatsu Castle Ruins (Takamatsu-jō Ato), also known as Tamamo Park (Tamamo Kōen), are a historic landmark located in Takamatsu City, Kagawa Prefecture.

Construction of Takamatsu Castle began in 1588 (Tenshō 16) under Ikoma Chikamasa, a retainer of Toyotomi Hideyoshi. It was later renovated by the Matsudaira family and prospered as the center of domain administration.

Takamatsu Castle is sometimes counted among Japan’s three great water castles, and is known for its unique structure that draws seawater from the Seto Inland Sea into its moats.

Today, the site is maintained as Tamamo Park, where visitors can enjoy nature and history, including Important Cultural Properties such as Tsukimi Yagura and Mizunote Gomon.


Top Things to See at the Takamatsu Castle Ruins

1. Seawater Moats and Fish Feeding Experience

Takamatsu Castle is known as a “sea castle” (umijiro) that increased its defensive power by drawing seawater from the Seto Inland Sea into its moats.

Fish from the sea swim in the seawater moats, and the park offers a fish-feeding experience.

Feed can be purchased in the park (around 100 yen), making it a fun activity for both children and adults.

The scenery of a castle with seawater moats is a unique highlight you can enjoy only here.

2. Views from the Tenshudai (Castle Keep Foundation)

The Tenshudai, located at the center of the castle ruins, underwent stone wall restoration and maintenance from 2006 to 2013, and visitors can climb to the top.

From the Tenshudai, you can enjoy panoramic views of the Seto Inland Sea, central Takamatsu, and Sunport Takamatsu, and it is also a popular spot at sunset.

The original castle keep was dismantled in 1884 (Meiji 17) due to deterioration, and efforts toward reconstruction are ongoing.

3. Seasonal Natural Beauty

At Tamamo Park, you can enjoy nature in every season.

  • Spring (late March to early April): Somei Yoshino and weeping cherry blossoms bloom around “Sakura no Baba,” making it a popular cherry blossom viewing spot.
  • Summer (July to August): Fresh greenery is beautiful, and tree shade provides relief from the heat.
  • Autumn (mid-November to early December): Autumn leaves color the entire park, making it an excellent season for photography.
  • Winter (December to February): You can enjoy a calm stroll in the crisp air and a tranquil atmosphere.

4. Touring Historic Buildings Designated as Important Cultural Properties

Within Tamamo Park, there are Important Cultural Properties including “Tsukimi Yagura,” “Mizunote Gomon,” “Watari Yagura,” and “Ushitora Yagura.”

Tsukimi Yagura is a three-story corner turret built in 1676, and was also called “Chakumi Yagura” because it watched for the arrival of the domain lord’s boat.

Mizunote Gomon is a castle gate facing directly onto the sea, and it is said that the domain lord boarded a small boat from this gate to reach a larger ship offshore.

The wooden reconstructed Sakura Gomon is also one of the highlights.

Frequently Asked Questions

A. Tamamo Park is a park developed around the historic site of the Takamatsu Castle ruins, known for its “water castle” scenery with moats filled with seawater. Because the water’s look changes with the tide, visiting the same spot at different times can give your photos a different feel. Signage can differ by location, so snapping a photo of a map at the entrance helps you avoid getting lost.
A. The West Gate can open as early as 5:30 in some seasons, while in winter some months start around 7:00. The East Gate is 7:00–18:00 from April to September and 8:30–17:00 from October to March, and the park is closed from 12/29 to 12/31. Checking your return transport schedule in advance helps you enjoy the visit without rushing at the end.
A. Admission is ¥200 for adults (age 16+) and ¥100 for children (ages 6–15). The park is breezy in many spots, so walks near the water can feel cooler than expected; a light outer layer can help. Comfortable shoes and a lighter bag help reduce stress for both walking and photos.
A. Tamamo Park is within walking distance of JR Takamatsu Station and Kotoden Takamatsu-Chikkō Station. There are many traffic lights near the station, so if you’re short on time, deciding your entrance (West Gate or East Gate) in advance helps you avoid getting turned around. Weather and crowds can extend walking time, so it’s best not to pack your schedule too tightly afterward.
A. Hiunkaku is generally not open to the public on a regular basis. Exceptionally, it can be visited on free open days such as Jan 1–3 and May 5, so if you really want to see it, planning around those dates is the most reliable. Having some coins ready can make ticket and shop payments smoother.
A. If you’re only strolling the grounds, about 45 minutes to 1 hour is typical; if you also visit exhibition facilities, plan around 1.5 hours. The moat perimeter can be longer than it looks, so if you’re concerned about stamina, focusing first on the areas around the turret ruins you most want to see can raise satisfaction. Some areas have little shade, so preparing a hat and water early helps keep your visit comfortable.
A. Groups often arrive around midday, so for a quieter walk, morning or late afternoon tends to suit better. In months when the West Gate opens earlier, entering right at opening and doing a quick loop—then saving the rest of your time for city walking—can reduce crowd stress. Signage can differ by location, so snapping a photo of a map at the entrance helps you avoid getting lost.
A. Some paths are narrow, so the basic rule is not to stop and block the flow of people. Tripods can easily get in the way when it’s busy, so use them sparingly and enjoy photography within what signage and the surroundings allow. Checking your return transport schedule in advance helps you enjoy the visit without rushing at the end.
