The conservation of the site began back in the Edo period, when [[Fukuoka han]], under the daimyo of the [[Kuroda clan]], performed a survey of the foundation stones. Even as the eras changed, from [[Edo period|Edo]] to [[Meiji period|Meiji]] to Taishô to Shôwa, the spirit of conservation remained, and stelae and plaques were placed in honor of the site. Simple conservation efforts were centered upon the ruins of the main hall. | The conservation of the site began back in the Edo period, when [[Fukuoka han]], under the daimyo of the [[Kuroda clan]], performed a survey of the foundation stones.
