Maruoka Castle丸岡城
Built in 1576 by Shibata Katsutoyo and a National Important Cultural Property: the keep, with its stone-tile roof, was rebuilt in 1955 after the 1948 Fukui earthquake. Go before the sweet-shrimp lunch: the castle opens at 8:30 and takes ¥450 (last entry 16:30).
The keep is under a large repair from March 2026 to about November 2027, so you may see it behind scaffolding. It can only be entered on set dates: 1 to 8 November and 12 to 31 December 2026 (partial opening); on other days walk the grounds and see it from outside. Parking is free from 6:30 to 20:00, with 40 places at the castle and 140 in the Hyakuhitsu Keishō-kan lot to the north.
