01 / Chiriku Embankment
A layer of packed clay called"hagane" was set in the embankment's core.

Chiriku Embankment (千栗土居) is a Saga Prefecture historic site, built for flood control on the Chikugo River by Naridomi Hyogo Shigeyasu (成富兵庫茂安). A Ministry of Land, Infrastructure, Transport and Tourism document records that a layer of packed clay called "hagane" was put in its core, and that building took about 12 years. In the Meiji-era village reforms, Kita-Shigeyasu and Minami-Shigeyasu villages took "Shigeyasu" in their names out of respect for him.
