Historic Sites, Places of Scenic Beauty, and Natural Monuments of Kagawa

Tombs of a line of chiefs in Zentsuji, Kagawa, a Historic Site since 1984, from the third-century Nodain Kofun to the sixth-century Obozan Kofun.

Quarries on Shodoshima and in Higashi-Rokko where stone was cut for Osaka Castle, a Historic Site since 1972, with 1,612 marked stones left on Shodoshima.

Two medieval tile kilns, one square and one round, below Omizukami Shrine in Mitoyo, Kagawa, a Historic Site since 1932, where tiles and a tile inkstone were found.

On the northwestern coast of uninhabited Marugamijima Island, drifting in the Hiuchi-nada Sea off Kanonji City in Kagawa Prefecture, lies a globally rare exposure of orbicular norite. White plagioclase and purple hypersthene form concentric rings of stunning natural beauty in this stone, also called kikkaseki or chrysanthemum stone. Designated a National Natural Monument in 1934, this geological treasure can be appreciated through specimens at the Ibuki Island Folk Museum and panoramic views from chartered boats.

The Marugame Castle Ruins in Kagawa Prefecture preserve one of Japan's most impressive early Edo-period castles. The site is famed for its four tiers of stone walls, which together rise to about 60 meters — the tallest combined castle stonework in Japan. Crowning the hilltop is the smallest of Japan's twelve surviving original wooden keeps, completed around 1660. Designated a National Historic Site in 1953, Marugame remains a remarkably intact example of early modern castle architecture.
