町家

Machiya (町家) means 'town house' — machi (町, town, street) + ya/ie (家, house). The machiya was the standard dwelling and workplace of the chōnin — the merchant and artisan class who inhabited the commercial districts of Edo-period Japanese cities, above all Kyoto. Its defining constraint was taxation: Edo-period city governments taxed properties by street frontage. The merchant's response was architectural genius — minimize the front, maximize the depth. The machiya has a facade of perhaps five to seven meters; its interior may extend twenty-five meters or more from the street.

The machiya was organized around a spine running from the front shop (mise no ma) through the living quarters (oku no ma) to the kitchen (daidokoro) and a garden (tsuboniwa) that admitted light and air to the building's interior. The garden was not decorative — it was structural, solving the problem of how to bring daylight and ventilation into a building sixty percent of which would otherwise be lightless. The machiya's narrow garden courts are the ancestors of the light wells in modern urban architecture.

The building material was wood, but machiya walls were coated with clay plaster (nuri-kabe) to resist fire — a constant danger in densely built cities. The deep eave (noki) protected the clay walls from rain. The inu-yarai — a curved bamboo or wood screen angled outward from the base of the wall — deflected rainwater and foot traffic and defined the boundary between public street and private house without a fence or gate. The machiya's front was completely permeable to the street, yet unmistakably domestic.

By the mid-20th century, thousands of machiya had been demolished in Kyoto, replaced by concrete buildings. But since the 1990s, a powerful preservation and renovation movement has reversed the trend. Machiya are now converted into restaurants, boutique hotels (ryokan), design offices, and homes for younger residents who find the proportions of a 200-year-old townhouse more livable than modern concrete. The narrow townhouse with its interior garden and permeable front has become an object of global architectural interest.
