1. From sun-dried mud to fired brick in ancient Mesopotamia
Brick's oldest relative is mud brick, sometimes called adobe. Some accounts place the first sun-dried mud bricks in Egypt and Mesopotamia — roughly the region of modern Iraq — and Babylon as early as 8000 BCE. By around 5000 BCE, ancient Egyptians were already using sun-dried brick alongside stone to build temples, palaces, and houses[1].
After roughly 3000 BCE, people worked out how to fire clay at high temperatures instead of just drying it in the sun, and fired brick spread outward from Mesopotamia into Egypt, the Middle East, and Asia. Fired brick is stronger than sun-dried brick and holds up much better against rain and flooding, so builders began using it for bigger structures. It was also a key material in Roman infrastructure projects[1].
2. Shape the clay, dry it, then fire it
Brick starts as clay. Water is worked into the clay, and the mix is packed firmly into a wooden or metal mold to give it its rectangular shape. Once it comes out of the mold, it sits outdoors to dry. If you stop right there, what you have is sun-dried brick[2].
Fired brick adds one more step: baking the dried block at very high heat in a kiln. Shaping can be done by hand or by machine, and firing methods have changed a lot over time — from burning bricks in the open, to purpose-built kilns such as the "daruma" kiln and the climbing kiln, and eventually to large continuous kilns. Firing drives the remaining water and organic material out of the clay and triggers a chemical change that makes the brick hard and dense, which is what gives fired brick its much better resistance to water and fire[2].
3. A French engineer helped build Japan's first serious brick project
In Japan, wood was the dominant building material right up through the Edo period (which ended in 1868), and brick was barely used at all. That changed once Western building techniques started arriving in the late Edo and early Meiji periods[3].
In 1872, the Tomioka Silk Mill was built in Gunma Prefecture, with the French raw-silk engineer Paul Brunat overseeing the technical side. Its main buildings were built using a "timber-frame brick" technique — a wooden skeleton combined with brick walls — topped with traditional Japanese roof tiles, blending Japanese and Western construction in a single structure. The brick walls were laid in a pattern called Flemish bond (フランス積み, literally "French bond," in Japanese), which alternates the long face and short face of each brick within a single row. At the time, this bond was still unusual in Japan[3].
4. Shibusawa Eiichi builds a brick factory, and imports a giant kiln
After the Tomioka Silk Mill, brick was suddenly needed all over Japan for the country's modernization projects. The businessman Shibusawa Eiichi founded the Japan Brick Manufacturing Company in the Jōshikimen area of Fukaya, in Saitama Prefecture. Under the guidance of a German engineer named Chiese, the company's first kiln was completed in 1888[4].
Later, the company installed a Hoffmann ring kiln, a design patented by the German engineer Friedrich Hoffmann. Kiln No. 6, completed in 1907, was about 56.5 m (185 ft) long, 20 m (66 ft) wide, and 3.3 m (11 ft) high, divided into 18 firing chambers, with a production capacity of roughly 650,000 bricks a month. Bricks fired here went into some of modern Japan's best-known buildings, including the Marunouchi building of Tokyo Station, the old Bank of Japan building, and the Akasaka Palace (now the State Guest House)[4].
5. Different bonds for different jobs: English bond vs. Flemish bond
A brick's long face is called a "stretcher," and its short face is called a "header." Different ways of arranging stretchers and headers produce different brick bonds, each with its own look and its own structural behavior[5].
English bond stacks a full row of stretchers, then a full row of headers, alternating row by row. It's prized for strength, and it also uses fewer bricks for the same wall. Flemish bond — called "French bond" in Japan, though internationally the term is Flemish bond — alternates stretchers and headers within every single row, which gives it a more decorative finish; this is the pattern used at the Tomioka Silk Mill. There are other bonds too, such as an all-stretcher bond and an all-header bond (useful for curved walls), and builders have chosen among them depending on the strength, appearance, and purpose they needed[5].
6. The Great Kanto Earthquake exposed brick's weak point
Britain, where the Three Little Pigs story is set, almost never has earthquakes. Its real threat is strong wind, and a heavy, sturdy brick house holds up extremely well against that. In that environment, brick really was one of the safest choices you could make[6].
Japan is a different story — it's one of the most earthquake-prone countries in the world. The Ryōunkaku, a 52 m (171 ft) tall, 12-story brick tower in Tokyo's Asakusa district completed in 1890, collapsed from the eighth floor up during the Great Kanto Earthquake on September 1, 1923, killing a dozen or so onlookers. Other brick buildings around the country, including the Yokohama District Court, were also badly damaged[6].
Brick construction is heavy, and that weight amplifies the forces a building experiences when the ground shakes — a genuine structural weak point for earthquake resistance. After the Great Kanto Earthquake, Japan shifted away from brick toward reinforced concrete, a material far better suited to withstanding earthquakes, as its new standard for major buildings. That said, some structures — railway works among them — had already begun switching to reinforced concrete before the earthquake, so the 1923 disaster wasn't the only reason brick construction declined in Japan. The material the story treats as unbeatable turned out to have a weakness the story never had to think about.
If you want to look for yourself
Next time you're walking somewhere with old brick buildings, look closely at how the bricks line up. See if you can tell whether it's English bond — full rows of stretchers alternating with full rows of headers — or Flemish bond, with stretchers and headers mixed within each row. And if you ever visit Japan, places like the Tomioka Silk Mill in Gunma, the former Japan Brick Manufacturing Company site in Fukaya, Saitama, and the Yokohama Red Brick Warehouse still let you see historic brick construction up close — on-site information panels there often note which bond was used and where the bricks came from, a way to check the history in this article against something you can actually stand in front of.
