Roof Tilers

If there's one thing that makes Japanese homes immediately identifiable, it's their roofs—or, to be more specific, the tiles that make up those roofs. These intricate tiles, which have been part of the Japanese landscape for well over a millennium, are the handiwork of roof tilers, who share the same passion for their craft as generations of tilers before them. On this edition of Japanology Plus, we take a look at the long history of Japan's roof tiles and meet the people dedicated to keeping the tradition alive.

Japanese tiles have an extremely long history, stretching back some 1,400 years. For about a millennium, however, they were used exclusively on the roofs of religious structures, or the homes of the elite. They began to be used on regular homes about 300 years ago, in the Edo period, thanks to a government decree promoting their adoption to help prevent fires. Before tiled roofs became widespread, citizens used other fire-resistant roofing materials such as mud and… oyster shells!

Japanese roof tiles are practical; they prevent fires, keep out rain and more. But they're also decorative, and on the program, we see many examples of the decorative tiles adorning roofs across Japan. Of all these decorations, some of the most ostentatious are oni-gawara—literally, demon or ogre tiles. These tiles can often be spotted topping Buddhist temples looking fearsome (you can spot a great example about 8 minutes in) and are said to ward off evil. Oni aren't the only mythical creatures seen on traditionally-tiled roofs, however. Another common fixture is the shachihoko, an animal with the head of a tiger and the body of a carp. The most famous shachihoko in Japan are the pair on the roof of Nagoya Castle—though these ones are covered in gold.

After learning about the hard work and dedication behind Japanese roof tiles, this may come as a bit of a shock, but there are people out there who make it their business to smash them! Kawara-wari, or tile-breaking, is a tradition in which martial artists show off their skill by punching stacks of tiles in half. Recently, shops have been popping up around Japan for tourists and everyday folks to try tile-breaking as a form of stress relief. One has to wonder what the roof tilers featured on the program think of this practice!

Actually, they may be happy that traditional roof tiles are being used at all. As we learn near the end of the program, traditional roof tilers face a difficult future. Today, many Japanese houses use prefabricated roofs, and sales of tiles have plunged. 2 billion tiles were sold in 1970, but the current number is a mere quarter of that.

However, several companies are trying out innovative ways to keep the tradition going. One firm, for example, uses tile materials and production methods to create coasters, bowls, trays, pencil stands and more. Another makes oni-gawara for indoor display. Even if your home doesn't use tiles in the traditional way, items like this give you a chance to appreciate tile craftsmanship.

Another route is one taken by a major Japanese steel producer, which offers a version of the traditional roof tile made from titanium. Titanium tiles are lighter, stronger and less susceptible to corrosion than ceramic roof tiles, and are said to look just like the real thing—provided you don't get too close. The tiles have been used on famous Tokyo landmarks like Asakusa's Sensoji Temple. Next time you're in Tokyo, try to see if you can spot the difference!

Like many Japanese traditions, roof tiles and tilers face an uncertain future, but rather than simply disappear, it seems entirely possible they will instead adapt to suit the times ahead.
