Reverberatory furnace constructer, Egawa Tarozaemonhidetatu

I got off JR Mishima Station at Nirayama Station on Izuhakone Railway, and, to a 20-minute walk, there is world's cultural heritage, Nirayama reverberatory furnace. This inheritance is comprised of 8 areas in Japan, 23 assets as "Industrial Revolution inheritance of Meiji Japan, iron manufacture, steel, shipbuilding, the coal mining industry", and it is one of the places registered with world's cultural heritage in July, 2015.
I visited a house of Egawa Tarozaemonhidetatu who was the constructer before observing the reverberatory furnace. There is the Egawa house in the place of around five minutes by car from a reverberatory furnace and is an important cultural property. When I purchase an admission ticket at an entrance and enter the house, there is a square open space used as training ground of the agrarian soldier by the late Tokugawa period, and a central room (24m *18m, ridge high 12m) is seen in a front gate, the depths in the front. When I advanced along the regular route and entered central room, there was a dirt floor of the area of approximately 50 tsubos. There was "a furnace" in the north side center of this dirt floor, and, on the east side, there was the pillar which the tree of the zelkova which grew was just used for, and the ceiling was able to just see the roof truss of the garret because it was not formed. A history document of the Egawas was displayed when I entered the room at the dirt floor.
The Egawas descended from Seiwa-Genji and assumed MInamotono Mitsunaka's second son, Uno Yorichika ancestors of a family and they hardened the ground afterwards as a powerful family of Izu in Kamakura, the Muromachi era and checked a family name with Egawa at the mid-15th century. Izu became the government controlled area of the Shogunate for Tokugawa era, and they governed this ground as a chief administrator. The present head of a household gives Tarozaemon from generation to generation, and the 36th generation is Egawa Tarozaemonhidetatu. The European and American Great Powers was the times when a colony made Asian each place it in sequence for the late Tokugawa period, and Hidetatu knew the foreign society circumstances and international situation and was concerned about a situation put Japan and proposed the coast defense and agrarian soldier training, the West gunnery study for the Shogunate. As the result, he constructed Odaiba of Tokyo Bay (battery for the coast defense) and the Nirayama reverberatory furnace (blast furnace for guns casting). In addition, he is said to be "the bread father" by having produced bread as mobile food of the agrarian soldier first in Japan.
The grounds include a manure storehouse, 2 rice storages, an arsenal, a well other than a central room.

Nirayama reverberatory furnace

As for the reverberatory furnace which existed in Japan, there were the others of Nirayama in Hagi of Yamaguchi, and this was registered with this world's cultural heritage. Guidance center was established in the place with the Nirayama reverberatory furnace. The commentary that is easy to understand the situation at the time of times setting and the operation that led to the building of the reverberatory furnace, an action to preservation in a picture and a showpiece is done there. In addition, a volunteer guide illustrates by the real reverberatory furnace visit. According to the explanation of the guide, The reverberatory furnace was going to be prepared into Shimoda of Izu at first, but, there was concern known to the foreign country making a reverberatory furnace by the visits such as black ships. So it was performed in Nirayama where the circumference was surrounded in a mountain, and the river which was a power source of supply flowed through the neighborhood. to. Four furnaces in total are located, and the Nirayama reverberatory furnace has height of the chimney of approximately 15.7 meters. As for the reverberatory furnace, the ceiling in the furnace becomes the dome type. It is the structure which can realize a high temperature of one thousand several hundred degrees that can dissolve casting iron by letting heat and the flame which produced coal as fuel reflect on the ceiling in the furnace, and centralizing it in one point. This iron which melted was poured into the mold of the cannon, and a cylindrical cannon seemed to be made. The power source such as the waterwheel which turned using the flow of the river was used, and the hole of the cannonball seemed to be opened with a drill-formed thing.In addition, the sample of the cannon is displayed in guidance center and before the reverberatory furnace.
