Place comparison
Tokyo’s 23 special wards compared with Taiwan: area, population and density
Tokyo’s 23 special wards occupy about 1.7% of Taiwan’s land yet hold roughly 42% of its population, so ward density runs about 24 times Taiwan’s national average.

On a familiar scale
- Tokyo 23 Special Wards ≈ 58% of Changhua County (reference rung) 64 m² of land per resident
- Taiwan ≈ 12.3 × Kaohsiung City (reference rung) 1,554 m² of land per resident
Reference scales come from Department of Household Registration, Ministry of the Interior: Land area, households and population density by township and district (year-end 2025) , as of 2025-12-31.
How to read it
This pairs an urban core with a whole country, so the density gap is mostly a statement about what each unit contains rather than about how people live.
Geography and shape
The 23 wards sit on the flat eastern edge of Tokyo Metropolis where the Kanto Plain meets Tokyo Bay, and almost all of that land is built on. Taiwan is an island territory whose central range and eastern slopes carry very few residents. Scaled to one map, the wards are a small patch beside Taiwan, which is exactly why the density figures diverge so far.
Population context
The wards hold roughly 42% of Taiwan’s population on about 1.7% of its land. Neither figure is surprising on its own; together they show why comparing a city core with a country tells you more about the units chosen than about either place. Taiwan’s own urban west coast is far denser than its national average.
Boundaries and definitions
This page uses the 23 special wards rather than Tokyo Metropolis, which is a prefecture that also administers the Tama mountains and the Izu and Ogasawara island chains reaching roughly a thousand kilometres into the Pacific. Japan’s Geospatial Information Authority marks the 23-ward subtotal as a reference value and it includes 4.68 km² of reclaimed bay land belonging to no single ward, so the figure cannot be rebuilt by summing wards or by measuring the outline. Taiwan uses official administrative land area and registered population.
Tokyo 23 Special Wards: The 23 special wards only, not Tokyo Metropolis and not the wider Greater Tokyo area. The wards hold about 70% of the metropolis population on under 30% of its land; the metropolis additionally contains 26 cities, 13 towns and villages and the Izu and Ogasawara islands. The area is a Geospatial Information Authority reference value because five wards have partly undetermined boundaries, and it includes 4.68 km² of river-mouth and bay landfill not assigned to any individual ward. Daytime population is far larger than the resident count: the 2020 census recorded 12.35 million people in the wards on a weekday.

In-depth guide
How should Tokyo 23 Special Wards and Taiwan be understood in context?
Tokyo’s 23 special wards fit into Taiwan about 58 times over, yet they hold roughly 42% of Taiwan’s population. That single sentence is the whole comparison: 1.7% of the land, 42% of the people.
What the density gap is actually measuring
The wards run about 24 times Taiwan’s national average density. Before reading that as a statement about crowding, notice what is inside each denominator. The 23 wards are almost entirely built up. Taiwan’s denominator includes the Central Mountain Range and the eastern slopes, where almost nobody lives, so the national average is pulled far below the density of the western plain where most Taiwanese actually live.
A fairer way to phrase it: this page compares an urban core with a country. The result is real arithmetic, but most of the gap comes from the choice of units. If you want a like-for-like city comparison, the wards against Taipei City is the pairing to use, and there the ratio falls to under two.
Which Tokyo, and why the area cannot be checked the usual way
Tokyo Metropolis is a prefecture that also administers the Tama mountains and the Izu and Ogasawara chains, reaching roughly a thousand kilometres into the Pacific. Its outline is mostly open sea and its density is diluted by land nobody lives on, so this page uses the 23 wards — the urban core, and the Tokyo a visitor experiences.
One caveat worth carrying: Japan’s Geospatial Information Authority publishes the 23-ward subtotal with a reference-value mark, because it includes about 4.68 km² of reclaimed land in Tokyo Bay that belongs to no single ward. Summing the 23 wards does not reproduce the published total, and neither does measuring the drawn outline. The two usual ways to verify an area both fail here for a documented reason.
Questions people ask
About this geographic comparison
Which is bigger, Tokyo 23 Special Wards or Taiwan?
Taiwan is bigger, with a land area about 57.7× that of Tokyo 23 Special Wards (627.5 vs 36,197.3 km²).
How do Tokyo 23 Special Wards and Taiwan differ in area, population and density?
Tokyo 23 Special Wards is 1.7% the size of Taiwan — 627.5 km² vs 36,197.3 km². Population is 42.4% as high; average density is 24.4× higher. Each side’s scope and reference date are set out under “Boundaries and definitions” on this page.
Is Tokyo bigger than Taiwan?
No, under any definition of Tokyo. The 23 wards are about 1.7% of Taiwan, and even Tokyo Metropolis including its mountains and remote islands is only a small fraction of Taiwan’s land area.
Why compare the wards with a whole country?
Because that is how the question is usually asked. The pairing is legitimate for scale, but the density result should be read as a consequence of comparing a built-up core with a territory that includes mountains, not as a statement that one place is 24 times more crowded to live in.
