Nirayama Reverberatory Furnace

Nirayama Reverberatory Furnaces (韮山反射炉, Nirayama hansharo) are a set of four Edo period reverberatory furnaces erected by the Tokugawa shogunate in what is now the Nirayama neighborhood of the city of Izunokuni, Shizuoka in the Tokai region of Japan. The site was designated a National Historic Site in 1922.[1] and was later designed as part of a World Heritage Site in 2009.[2]

Background

During the Bakumatsu period, the Tokugawa shogunate was increasing alarmed by incursions by foreign warships into Japanese territorial waters, fearing that these kurofune warships would attempt the end Japanese self-imposed national isolation policy by force, or would attempt an invasion of Japan by landing hostile military forces. Numerous feudal domains were ordered to establish fortifications along their coastlines with coastal artillery located at strategic locations, and the shogunate made belated attempts to modernize its armed forces.

Egawa Hidetatsu, daikan of the Nirayama Daikansho [3] was assigned a leading role in the reinforcement of Japanese coastal defenses around Edo Bay in 1839.[4] As early as 1842, Egawa attempted to build a furnace to cast cannon in the village of Nirayama in the Izu Peninsula. After sending a student to study the design of a furnace which had been developed in Saga Domain based on Dutch technology, construction began on a new reverberatory furnace in November 1853. It was completed in 1855, and the first cannon cast at the site in 1858. The facility was used until 1864.[5]

In 1868, the Egawa clan purchased the facility from the Tokugawa shogunate and in 1872 it was acquired by Imperial Japanese Army, who performed some repair work in 1908. After it became a National Historic Site in 1922, control was transferred to the Home Ministry with Nirayama municipality assuming responsibility for upkeep since 1957.

Design

The facility consists of four furnaces, each made from refractory bricks, on a stone base, with a height of 15.7 meters. The design of the furnaces was taken from a Dutch book, Het Gietwezen in's Rijks Ijzer - geschutgieterij te Luik, which the Japanese had received via the Dutch trading post at Nagasaki. The southern pair of furnaces were completed in 1855 and the northern pair in 1857.
