See How Traditional Japanese Carpenters Can Build a Whole Building Using No Nails or Screws

If it came down to it, most of us could hammer basic shelter together with enough wood and nails. But what if we just had the wood? And what if we needed to make not just a hut, but a full-fledged building: a livable house, or even a house of worship? That may well sound like an impossible task — unless, of course, you’ve trained as a miyadaiku (宮大工), the class of Japanese carpenter tasked with building and maintaining buildings like shrines and temples. Without a single nail or screw, miyadaiku join wood directly to wood — a method of joinery know as kanawatsugi (金輪継)  — and in so doing manage to build some of the world’s longest-lasting wooden structures, just as they’ve done for centuries upon centuries.

Back when this style of carpentry first developed in Japan more than a millennium ago, “it was difficult to acquire iron.” And so “people tried to build buildings only with wood,” making up for what they lacked in tools with sheer skill. So says Takahiro Matsumoto, a miyadaiku carpenter based in the city of Kamakura, in the Great Big Story video above

Japan’s de facto capital from the late 12th to early 14th century, Kamakura is still filled with Buddhist temples and Shinto shrines, some built more than 1,200 years ago. To build new temples and shrines, or to provide the existing ones with the repairs they need every century or two, a miyadaiku must master a host of differently shaped wooden joints, each of them developed over generations to hold as tightly and solidly as possible.

For another view of kanawatsugi, have a look at The Joinery, a library of explanatory animations previously featured here on Open Culture. You can see exactly how each of these joints are cut and assembled for real-life projects — as well as every other aspect of how miyadaiku put together a building — at the Youtube channel Japanese Architecture: Wisdom of Our Ancestors. The channel is aptly named, for only with a high regard for the carpentry knowledge gradually built up, tested, and refined by their predecessors could today’s miyadaiku do their work. “Advanced skills are needed, but we work with the old buildings built by our ancestors,” says Matsumoto. “Today, we also learn from the ancestors’ skills, since the old buildings themselves are standing documents of those skills.” Each and every one testifies to how, for want of a nail, some of the most admired architecture in the world was born.

    The article describes building with only wood, but the headline says “No Nails or Wood.” That would be a neat carpentry trick indeed!

    You might want to change the strapline at the top of this article.
    They may not have used nails but they certainly used wood!

  • Lonnie says:

    Has no one taught millennials to proof read their work? Journalism is going downhill fast!

  • Trevor says:

    I hate when I have to build a wooden building with no wood. That’s the worst.

    Clickbait titles should be illegal everywhere.

    In no way is dovetailing and joinery exclusive to Japan.

    In history, Japan has had her share of slaughtering Christian missionaries and trying to take over the world, but not a monopoly on woodworking!

    There are hundreds of joints, unsure why you single out the dovetail joint (which is the English name for it).
    Also the amount of documented joints in Japan is massive, the amount in England is much smaller and there are nearly no long existing examples in England of advanced woodworking. So if you are claiming England introduced this to Japan, you are historically moronic.

    BTW the first English person didn’t even reach Japan until 700+ years after Japanese woodworking existed, so you have a huge time issue there in your low IQ made up belief.

    The fact is that Japan has the most advanced woodworking techniques ever documented, and even German visitors like Einstein were marvelled at this, which is written in his diary. No other country has such wooden joined structures as Japan has, especially at the age Japan’s originate.

    As far as “Christian missionaries”, gives me a break. The first countries to have contact with Japan were the Portuguese and Spanish, and they openly tried to attack Japan’s native religions by calling them sinful, and then trying to take over with Christianity. You blame Japan for defending itself against attempted colonisation? You are a joke.

    Additionally Japanese were captured in lower islands by the Portuguese and sold off as slaves in the international slave trade. This is the straw that broke the camels back, leading Hideyoshi to ban slavery in 1590, and the Abolish Europeans from Japan. Which ended their attempts at colonising Japan.

    Japan however did continue to trade with the dutch for some time after this, because the dutch would trade with no strings attached, meaning they didn’t try to Christianise the country or enslave people or try to start a colonisation attempt.

    As far as Japan trying to take over the world, this never happened in history. Now if you are going to say England tried to do this, that is true. But Japan never did.

    The lands Japan invaded were lands that were invaded and occupied by European empires, Japan invaded these to free Asia of European colonisation, because Japanese leaders thought that Japan (one of the only 2 nations not yet colonised) would be colonised next unless they push Europeans out of Asia.

    Indeed if Japan didn’t stick up for itself and build up it’s military and take on European empires, it would have the exact same fate as the Filipino or Vietnamese (invaded, colonised, loss of native writing, conversion to Christianity, mass rape of civilians, enslaved on plantations etc).

    European colonialism died after Japan rose, every European empire collapsed into just being a nation state, because without the overseas lands and the ability to run slave plantations and pillage resources from mines etc, the European country itself (whether it be France, Holland, England etc) would no longer have the monetary resources to be an empire.
