Why Kyoto Machiya Are So Long and Narrow: The Frontage Tax That Shaped the 'Eel's Bed' Townhouse

Blame the tax man. Kyoto's traditional townhouses look like a hallway that kept going because, for centuries, the city charged property tax by street frontage, not total floor area. The narrower your house faced the road, the less you paid. So merchants built skinny and deep — 4 to 6 metres wide, 20 metres or more long — and the Japanese nicknamed the result unagi no nedoko: an eel's bed.

What Is a Machiya?

A machiya is a traditional wooden townhouse where merchants and craftspeople lived and worked, shop up front, home behind. The classic Kyoto version — a kyomachiya — is two storeys, built of timber, clay, and baked tile, with a lattice facade that once advertised the owner's trade. Think of it as a live-work space designed centuries before anyone used the phrase "open plan," with sliding doors that let you reshape the house by the hour.

The truly defining feature, though, is the proportions. Most machiya are only 4 to 6 metres wide but run 20 metres deep or more. That's the footprint of a bowling lane, and it's deliberate.

A Tax on Width, Not Space

During the Edo period (1603–1868), Kyoto levied a property tax based on the length of a building's street frontage — the maguchi — not on its total floor area. The wider your house faced the road, the more you paid. So merchants, being practical people, did the obvious: they built skinny and long. You paid for 5 metres of frontage but got a home that stretched 20 metres back, with room for a shop, living quarters, a kitchen, storehouses, and a tiny courtyard garden called a tsuboniwa that pulled light and air into the middle of the house.

This frontage tax turned the width of your plot into a public flex. A 6-metre-wide machiya meant you were doing well; a 4-metre one meant you were getting by. But everyone, rich or modest, played the same game: minimise the street-facing measurement, maximise everything behind it.

The result is a house that uses every inch of its narrow width to pull light and air deep inside. You enter through the mise no ma (shop space), step up into the raised living rooms with tatami mats, then follow the tōriniwa — an unfloored earthen passage that runs the length of the house like an indoor alley — past the kitchen, under the hibukuro chimney-skylight, all the way to the back garden and the kura storehouse. The whole sequence is a masterclass in doing a lot with a little width.

The frontage tax was abolished after the Meiji Restoration in the late 19th century, but by then the eel's bed shape was baked into Kyoto's DNA. The city still has roughly 40,000 machiya, though about 800 are demolished every year.[^1]

Why Kyoto Kept So Many

Two other factors helped these eel's beds survive. First, Kyoto was removed from the Allied bombing list during WWII — a story often told that the US war minister had honeymooned in the city and couldn't bring himself to destroy it.[^2] Second, the city sits in a basin ringed by mountains, which means fewer typhoons and earthquakes than, say, Tokyo. So while other Japanese cities lost their old wooden townhouses to war or disaster, Kyoto held onto them.

Why It Matters to a Visitor

You don't need to study architectural history to feel the difference. Step into a restored machiya like BenTen Residences in Higashiyama or one of the Old Kyoto townhouses, and the narrowness becomes a kind of intimacy. The garden at the back — open to the sky, maybe just three metres square — feels like a secret you earned by walking the whole length of the house. Sit there with a cup of tea while rain hits the moss, and you'll understand why the tax dodge was worth it.

If you just want a look without spending the night, several machiya open their doors to the public. Nishijin Tondaya, a restored townhouse in the old weaving district, offers tours that explain the customs of Kyoto's merchant class.[^3] In the Shimabara area, the Sumiya Motenashi Art Museum — once the largest machiya in the city — is open seasonally and gives a rare glimpse of an Edo-period entertainment house that's not a temple or a palace.[^4] And Maikoya Teahouse in Nakagyo runs machiya tours alongside tea ceremonies, so you can drink matcha in the same kind of long, narrow room a merchant once used.[^5]

FAQ

Why are machiya called "eel's beds"?
Because unagi no nedoko literally means "eel's sleeping place" — a long, narrow shape that resembles the body of an eel. It's a nickname Kyoto locals gave their own houses, half affectionately, half because it's true.

Was the frontage tax unique to Kyoto?
Not entirely. Other Japanese cities used similar systems, but Kyoto's machiya became the archetype because so many survived. The tax principle — charge by street frontage, not total area — was common in Edo-period urban planning.

Can I stay in a machiya today?
Absolutely. Dozens of restored machiya operate as licensed vacation rentals across Kyoto, from budget-friendly guesthouses to luxury townhouses with heated floors and Nespresso machines. They're the sweet spot between a ryokan's formality and a hotel's anonymity — you get the whole house to yourself, garden included.

Next time you walk down a lane in Gion and pass a wooden lattice facade, look at the pattern. Rice shops had one style, thread shops another, geisha houses a vermillion-red version. The lattice was the original shop sign. Four centuries later, the tax dodge is still telling stories.
