Ginzan Area in Iwami Silver Mine
Iwami Silver Mine produced approximately one third of total silver amount in Japan in the late sixteenth century and the beginning of the seventeenth century. As Silver production from Iwami Silver Mine brought wealth to "Edo Bakufu", the central government of Japan ran by TOKUGAWA Clan in the Edo Age (1603-1868), "Edo Bakufu" directly governed Iwami Silver Mine and placed the Omori Magistrate's Office.Please refer the top page of "Iwami Ginzan" for the information of other areas: http://handejapan19.html.xdomain.jp/TravelDestinations/Chugoku/IwamiSilver_E.html The mining galleries were located to the south of Rakanji Temple. This area is named "Ginzan" Area, which means "Silver Mines" in Japanese. In Iwami Silver Mine, one thousand of abandoned mining galleries remain. Some of them are open for public. You are also able to visit the sites of silver mine smelters. Ginzan AreaTo the south from Rakanji Temple, the rural scenery is spread. If you walk eight hundred meters to the south from Rakanji Temple, the grave of OKUBO Nagayasu (1545-1613) , who was the first magistrate of Iwami Silver Mine, is located in mountains.Please refer the page of "Omori Magistrate's Office" for the detail information of OKUBO Nagayasu: http://handejapan19.html.xdomain.jp/TravelDestinations/Chugoku/OmoriMagistrate_E.html After OKUBO Nagayasu was died, he was condemned that he made illegal savings to take advantages of his positions. Then, his grave was destroyed and his body was exposed to the public. Near the grave of OKUBO Nagayasu, the sites of the "Shimogawara-Fukiya", which is a silver smelter, is located along the street from Omori Magistrate's Office to the main mining galleries. The sites of the "Shimogawara-Fukiya" smelter was found in 1991 by the excavational investigations. The "Shimogawara-Fukiya" smelter was mainly used at the beginning of the seventeenth century. The smelting technology used at the "Shimogawara-Fukiya" smelter was the cupellation method and it was introduced to Iwami Silver Mine from China. If you walk another five hundred meters from the site of the "Shimogawara-Fukiya" smelter to the south, you will be at the entrance to "Shimizudani" Smelter. The "Shimizudani" Smelter is located in a mountain area. "Shimizudani" SmelterIwami Silver Mine was run by "Edo Bakufu", the central government of Japan during the Edo Age (1603-1868). After the Edo Age ended in 1868, Iwami Silver Mine declined and many mining galleries were abandoned.In 1894, the "Shimizudani" Smelter was newly developed by building the modern smelter with the investment corresponding to approximately a hundred million dollars in present currency value. |

Just two years after the operation of the "Shimizudani" Smelter stared in 1894, the silver production was stopped, due to the poor silver contents and not sufficient production capacity of the smelter. Halfway up the mountain, the site of a silver dressing facility is located. At the silver dressing facility, silver ore with high silver content was selected and delivered to the "Shimizudani" Smelter. The site of "Kuranojyo" Mining Gallery is located near the site of the silver dressing plant. When the "Shimizudani" Smelter started it's silver production, "Kuranojyo" Mining Gallery was abandoned. The ruins of gallery were used as a tunnel to deliver silver ore was transported through the abandoned "Kuranojyo" Mining Gallery. "Ryugenji-Mabu" Mining GalleryIf you walk 1.3 kilometers to the southwest from the site of the "Shimizudani" Smelter, you will finally arrive at the site of the "Ryugenji-Mabu" Mining Gallery. The "Ryugenji-Mabu" Mining Gallery was the one of the main mining galleries in Iwami Silver Mine and it was developed after the middle of the Edo Age. The site of the "Ryugenji-Mabu" Mining Gallery is open for the public. An abandoned gallery was excavated without timbering. The rock surface is exposed and you will see the chiseled works made in the Edo Age. |

In the mining gallery, the temperature is stable at thirteen degree C all the year around. If you visit the "Ryugenji-Mabu" Mining Gallery, it will be cold. You will see cracked rocks, as shown in the below picture. These cracks on a rock are the marks that boiled water flowed, where the silver content in a rock is high. The original the "Ryugenji-Mabu" Mining Gallery is a hundred and fifty-six meters in length. Eight layers of mining galleries pile up in the ground. The "Ryugenji-Mabu" Mining Gallery is located on the top layer. Vertical mining shafts connect these eight mining galleries. Ruins of Yamabuki CastleIn order to protect valued Iwami Silver Mine, a couple of castles and forts were built. Yamabuki Castle is one of such castles. It was built by OTOMO Hiroyuki (- 1352) in the Kamakura Age (1185-1333), when Iwami Silver Mine started to produce silver.Yamabuki Castle was located at the top of Mt. Yogai with 414 meters in height, which is located to the west between the "Shimizudani" Smelter and the "Ryugenji" Mining Gallery. Stairs continues to Mt. Yogai. After climbing up steep stairs for thirty minutes, you will be at Yamabuki Castle. Yamabuki Castle was abandoned in 1601, when the Omori Magistrate's Office was built. Please refer the page of "Omori Magistrate's Office" for more detail: http://handejapan19.html.xdomain.jp/TravelDestinations/Chugoku/OmoriMagistrate_E.html More than four hundred years has passed since Yamabuki Castle was abandoned.
