Although it is rare worldwide, there is a reason why Japan's Industrial Revolution became a World Heritage Site. The following is a quote from the World Heritage Center's official website, but from the world's perspective, it was as follows

This book tells the story of how feudal Japan sought to transfer technology from Europe and the United States, and then improved the imported technologies to suit domestic needs and traditions, quickly becoming one of the world's leading industrial nations. The collection of technologies in the key industries of iron and steel, shipbuilding, and coal mining demonstrates Japan's remarkable achievement as the first non-Western nation to successfully become an industrial nation, a remarkable achievement in world history

Above we have given a brief explanation of the constituent assets of the World Heritage Site "Sites of Japan's Meiji Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining." Among these assets, the Hashino Iron Mine, located in Hashino-cho, Kamaishi City, Iwate Prefecture, played an especially important role in Japan's industrial revolution

This is possible because of the nature of the Tohoku region, Iwate Prefecture, and Kamaishi City

Kamaishi Mine, a mine discovered before the Hashino Iron Mine in Kamaishi City, Iwate Prefecture

Why did we choose Kamaishi City, Iwate Prefecture? It wasn't because the sea stretched out before us, or because it just so happened to be in Iwate. It was because this area was home to Japan's largest iron mine, the Kamaishi Mine, an iron deposit formed by the reaction (contact alternation) of magma, which became granite, with the surrounding limestone.

Kamaishi Mine is located on the coast of the Kitakami Mountains, and is said to have a history of over 150 years since it was first opened in the Meiji era. In 1727, Abe Shoo a medicinal herb collector for the Edo Shogunate (a person who traveled around the country to collect and study medicinal herbs) , discovered magnetite (a type of iron oxide mineral) at Sennin Pass. In addition to the main mineral iron, gold, silver, copper, lead, and zinc were also produced, and even now, after the mine has closed, about 100 tons are still extracted annually for research purposes.

Abe Masao magnetite at Sennin Pass , in 1849 Takasu Seibei and Nakano Daisuke jointly built an old-style blast furnace in Ohashi.

Then in 1857, Oshima Takato , a samurai of the Nanbu domain, succeeded in tapping pig iron (the process of removing molten pig iron that has accumulated in a blast furnace) using a blast at the Hashino Iron Mine, and in 1862, two more blast furnaces were added, increasing pig iron production.

The father of modern iron manufacturing, Nanbu feudal lord Oshima Takato

As the city transitions from Japan's largest iron mine to its number one steel town, we must not forget the man who is indispensable for discussing steelmaking: Takato Oshima, the "father of modern steelmaking .

Born into a doctor's family in Morioka, he studied Dutch studies

Oshima Takato was born on May 11, 1826, in Niokoji, Morioka, as the eldest son of Oshima Shui, a physician to the Morioka domain. In 1842, at the age of 17, he traveled to Tokyo to study Western medicine, where he studied under Mitsukuri Genpo and Tsuboi Shindo

He became interested in modern weapons in Nagasaki and translated a Dutch book on iron reverberatory furnaces

He then studied in Nagasaki, where he became interested in Western military science, artillery, mining, and refining, and together with Choshu samurai Tezuka Ritsuzo translated Major General Huguenin's "Casting Methods at the Royal Iron Cannon Foundry of Loic," which

Invited by the Mito domain, he succeeded in building an iron reverberatory furnace

Later, he was invited by the Mito domain and succeeded in building a reverberatory furnace in Nakaminato and casting cannons, but the performance was not high because the raw material was iron sand. After that, in order to produce high-quality iron, he built a Koshimura Ohashi (now Koshicho Ohashi, Kamaishi City, Iwate Prefecture) and as mentioned above, in 1857 he became the first in Japan to successfully operate a pig iron production plant by refining iron ore.

Why is Oshima Takato called the "father of modern steelmaking"

World Heritage Site Hashino Iron Mine (Hashino Blast Furnace Ruins)

The World Heritage Site "Hashino Iron Mine (Hashino Blast Furnace Ruins)" is located in Hashino-cho, Kamaishi City, Iwate Prefecture

It was designated a national historic site in 1957, received the Historic Heritage Award (HL Award) from the American Institute for Metals in 1984, and was included in the World Heritage Site "Sites of Japan's Meiji Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining" in 2015. The registered name of the World Heritage site is "Hashino Iron Mine," which collectively refers to the remains of the iron ore mine, transportation route, and blast furnace

At the very back of the Hashino blast furnace ruins there is a gate to the iron mine, and although the road continues as a forked forest road, it is off-limits as it is national forest beyond that point

Hashino Blast Furnace Ruins

The Hashino Blast Furnace Site is the oldest surviving blast furnace site in Japan. On December 1, 1858, Oshima Takato constructed a Western-style blast furnace in Ohashi (near the current site of the former mine office) using Dutch books as reference, and succeeded in continuously producing iron. The following year, in 1858, operations began with a temporary blast furnace (now the No. 3 blast furnace), marking the beginning of the Hashino Iron Mine

The reason why blast furnaces were built deep in the mountains of Hashino-cho, Kamaishi City, was not simply because high-quality magnetite could be extracted there

In addition to iron, the mountain was also able to mass-produce high-quality charcoal, which is essential for steel production, and the small streams that flowed through it allowed waterways to be built, and hydroelectric bellows (devices that send air to burn fuels such as charcoal at high temperatures) were able to send enough air to the blast furnaces to produce iron, which was a major factor

As you walk around the site, slag, . There are various sizes, from pebbles to large pieces over 60cm in diameter.

This is a dissolved substance other than the target components that is generated when refining minerals such as iron, nickel, and chromium, and is considered a type of industrial waste. In other words, this slag is proof that the Hashino blast furnace was in operation at the time. As an aside, I personally found this slag more romantic than the remains of the blast furnace

When Hashino Blast Furnace was in operation, it employed around 1,000 workers, and in addition to the three huge blast furnaces, there were also tenement houses where the employees slept, a blacksmith's house, a watermill, a place where salaries were paid, and a shrine

At the current Hashino Blast Furnace site, you can see the stone walls of the three blast furnaces. Castle-style stone wall construction was used to build the blast furnaces' stonework, and Japanese wooden structures were used to cover the furnaces. Documents show that they were about 10 meters high. They were built by Oshima Takato using Japanese technology in order to produce steel that could compete with the world

By the way, there are three blast furnaces at Hashino, numbered one through three, with the first to be built being the third blast furnace, and these numbers are counted from upstream
