01 / Mausoleum hall
An inscription behind the frieze board shows the Shoeidowas built earlier than previously thought.

The town describes the Shoeido as a mausoleum building that Tadafusa, the 6th head of the Fukozu Matsudaira family, lords of Shimabara, built to enshrine his father Tadatoshi. A full dismantling repair began in Reiwa 4 (2022), and reassembly took place in fiscal Reiwa 7 (2025). Excavation of the platform confirmed a stone chamber inside it.
