Why did only this district escape the fire?

Not a single cause, but a mix of hill-and-valley terrain and the firebreaks made by the open ground of temples and cemeteries is said to have spared it the great fires of the earthquake and the air raids. That is why the wooden houses and alleys remain.

Edo-to-prewar wooden shops and houses, narrow winding alleys, and some sixty temples. Few places in central Tokyo keep old wooden scenery at this density.

Was it “preserved”?

Closer to “remained”. It was not protected for preservation from the start but survived by the accident of escaping disaster; only later did residents’ records and machizukuri (Eps. 2 and 9) begin to keep it consciously.

The hill the fire passed by

Ep. 3 · Why only this district stayed wooden

FitTrip Editor · 2026.07.18

Tokyo’s wooden shitamachi was consumed by two great fires in the twentieth century — the 1923 Great Kanto Earthquake and the 1945 Tokyo air raids. Yanaka largely escaped both, through a mix of hill-and-valley terrain and firebreaks made by temples and cemeteries, and so Edo-to-prewar wooden houses and narrow alleys remain in the heart of the city. As Red Hook kept its old docks through the inconvenience of no subway and road isolation, Yanesen kept old Tokyo through the accident of fire passing by — a district where preservation was a result, not a plan.

To know why Yanesen’s alleys are so narrow and still wooden, you must know what this district escaped. The answer is fire.

The fire that burned Tokyo twice

Tokyo’s wooden shitamachi burned greatly twice in the twentieth century — the 1923 Great Kanto Earthquake fire, and the 1945 Tokyo air raids Fact. Both consumed dense wooden districts across wide areas; that most of central Tokyo is now concrete is their trace.

Where the fire passed by

Yanaka largely escaped both Fact. It is said to owe this to a mix of hill-and-valley terrain and the firebreaks made by the open ground of temples and cemeteries Estimate — common account. Whatever the cause, the result is clear: Edo-to-prewar wooden houses, narrow alleys and some sixty temples remain in the heart of the city Fact.

From accident to preservation

If Red Hook kept its old docks through the inconvenience of no subway and road isolation (our Red Hook series), Yanesen kept old Tokyo through the accident of fire passing by. Both share one thing: “preservation” was a result, not a plan from the start Estimate. And what later turned that accident into conscious preservation was Episode 2’s magazine, and the machizukuri of Episode 9.
