The Birthplace of the Modern Iron and Steel Industry


Hashino Iron Mining and Smelting Site: UNESCO World Heritage Recognition

At the 39th UNESCO World Heritage Committee Session held in Bonn, Germany, on July 5 2015, Kamaishi City’s Hashino Iron Mining and Smelting Site ruins were recognised as one of the World Heritage “Sites of Japan’s Meiji Industrial Revolution”.

The First Western-Style Blast Furnace in Japan

Iron has been manufactured from iron sand in Kamaishi since as long ago as the Heian Period (AD794 – 1185). However, after Takato Oshima built a western-style blast furnace in the Ohashi district in 1857, continuous production of iron from iron ore was achieved for the first time in Japan.
For this reason, Kamaishi is often referred to as “the birthplace of Japan’s modern iron and steel industry”. It would not be an exaggeration to say that Japan’s entire industrial revolution began from this small town.

The first domestic steelworks and steel utilization

From the dawn of the Meiji Period (1868-1912), steel manufacturing projects were sought to make use of the Ohashi iron mine. In 1880, the government-run Kamaishi Steelworks commenced operations as the first steelworks in Japan.
That same year, the third railway to be built in Japan was opened in Kamaishi and the city was recognised as vitally important to the country’s modernisation.

From Post-war Recovery to Present Day

Throughout the Taisho (1912 – 1926) and Showa (1926 – 1989) Periods, the Kamaishi Steelworks expanded in size alongside the technological advancement of the steel industry, and came to play a vital role in supporting the modernisation of the nation. However, the steelworks were destroyed in the two naval bombardments during the closing days of the second world war, which also caused extensive damage to much of the city.

After regular operations recommenced in 1948, the Kamaishi Steelworks developed into one of the leading steel manufacturers in Japan, producing high quality rails for Shinkansen tracks among other projects. Due to the boom in this industry, Kamaishi reached its peak population (approx. 91,000) in 1963, but declined once more after industry rationalization and the construction of new steelworks in other parts of the country.
Currently, the steelworks constructs machine parts, such as wires used in steel cords for car tires, and maintains the world-class quality of the Kamaishi brand.
