Marugame-jō

An easily spotted landmark high above Marugame’s streets, Marugame-jō (丸亀城; city.marugame.lg.jp/site/castle; adult/child ¥400/free) is one of Japan’s 12 remaining original castle keeps and Shikoku’s oldest. It takes 15 minutes on foot from Marugame Station, followed by a 10-minute schlep up a steep incline to the top, but the spectacular observation area at the halfway point gives an opportunity to catch breath while taking in the views of the town and the Inland Sea.
