🐦 Through Sea Castle Ruins and Famous Gardens: A 14km Ptarmigan Loop 🐦
Takamatsu City in Kagawa Prefecture, facing the tranquil Seto Inland Sea, has long served as a vital gateway to Shikoku. Flourishing as a prominent castle town ruled by the Ikoma and Matsudaira clans, it is famous for Takamatsu Castle—one of Japan’s Three Great Water Castles—and the breathtaking Ritsurin Garden.
This 14km GPS art course invites you to sketch a Ptarmigan across the city’s downtown layout, turning Takamatsu’s historical streets into a vast digital canvas.
The scenic loop begins south of Takamatsu Station. After weaving around Takamatsu Castle Park, Takamatsu-chikko Station, and the cultural Rexxam Hall, the route heads south along Prefectural Route 160. Passing the Takamatsu City Museum of History near Ritsurin Station, you will turn west toward the majestic Ritsurin Garden. The path guides you past sacred spiritual spots including Atago Shrine, Koken Temple, and the revered Iwaseo Hachiman Shrine. Heading north, the trail turns east along the Yosan Line, passing Takamatsu City Hall and the green expanses of Takamatsu Chuo Park, before reaching the grand finale around Kawaramachi Station.
This flat 14km trail seamlessly connects samurai history with seaside urban culture. When the digital Ptarmigan is complete on your map, you will have experienced the rich coastal charm of Takamatsu with every single step.
