More than 70 workshop sites lie in the mountains of the Nishisonogi Peninsula, and here 11 workshops cluster. On the wall of Workshop No. 6, about 6 m high and about 60 m wide, many unfinished pots and gouged hollows can be seen.

In 1563 (Eiroku 6) it burned in an attack by the anti-Sumitada faction, and the trading port later moved to Fukuda and then to Nagasaki. Yokoseura Park has a museum introducing the history of Yokoseura.

03 / Nishisonogi Peninsula Boar-Wall Base Stone

The inscription "Kyoho 7" on the base stonematches the Gosonki record of the start of work.

This is the base point of a stone wall built to keep boars and deer from the fields, at Nakaura. On the basalt is carved "Kyoho 7 □ tora year" (□ is one illegible character) in two lines, matching the Gosonki (郷村記) entry that work began in June of Kyoho 7 (1722). A 1976 survey found that the wall runs nearly all the way around the peninsula's mountains.

  • Prefectural designated tangible folk cultural property (designated April 23, 1968)
  • Each inscribed character is about 10 cm square (city)
  • 1976 survey: runs nearly all the way around the mountains (city)
