Rocks were cut open so boats couldcarry the tribute rice.
The town website writes that a great work cut through huge rocks with chisels and hammers so tribute rice could go by boat. The Ministry of Land, Infrastructure, Transport and Tourism writes that boats could reach Miyanojo after the Tenpo river dredging, which an Isa man proposed and which has a monument at Sogi Falls Park. The town-designated Gontaro Stone, found in the river while Tsuruda Dam was being built, bears an inscription praising the stonemason's work.
