Radius Map of Tokyo

The map above is centered on Tokyo, Japan, near Shinjuku Station, with a default 10 km radius. Drag to move it, search for a different address, or change the radius and unit using the controls.

Tokyo is the most populous metropolitan area on Earth, with about 37 million people in Greater Tokyo. The Yamanote Line — a 34.5 km loop around central Tokyo — is the city's informal radius marker. A 5 km radius from Shinjuku Station covers most of the Yamanote interior; a 10 km radius extends well past it into Setagaya, Ota, and Sumida wards. For commute and travel-time analysis, the train network rules — distance is a poor proxy for journey time without rail-aware tools.

How Tokyo radius maps get used

City-specific scenarios where a radius is the right tool — and the typical radius sizes professionals use.

Yamanote-aligned commute filter

A 5 km radius from any major Tokyo workplace approximates a 30-minute Yamanote-line commute, because the Yamanote interior is uniformly served by dense JR and Metro networks. Outside the Yamanote, train commutes branch onto private lines and journey time depends sharply on which line, not just distance.

Typical radius: 5 km for Yamanote-aligned commute

Konbini and depachika catchment

Tokyo's convenience stores (konbini) and department-store food halls (depachika) draw from extremely tight catchments — typically 200–500 m. A 1 km radius captures most overlapping foot traffic; competition is fierce inside this circle.

Typical radius: 0.2–0.5 km for ultra-local retail

Disney and Skytree day-trip planning

Tokyo Skytree (~10 km from Shinjuku) and Tokyo Disneyland (~18 km east in Chiba) sit inside a 25 km radius from central Tokyo. Hotel and tour operators use a 25 km radius to define "Tokyo-area attraction reach" for one-day itineraries.

Typical radius: 25 km for Tokyo attraction-area itineraries

Greater Tokyo enterprise market sizing

A 50 km radius captures roughly 30 million people — most of Greater Tokyo. This is the natural radius for enterprise-software TAM, retail chain expansion plans, and B2B addressable-market estimates in the Kanto region.

Typical radius: 50 km for Greater Tokyo enterprise

Geographic quirks of Tokyo radius mapping

Local geography and infrastructure that change how a radius behaves here. Skipping these is the most common reason a radius decision goes sideways.

The Yamanote Line is a literal radius

The Yamanote Line is a 34.5 km circular train route around central Tokyo, with 30 stations spaced about 1 km apart. It is one of the densest and busiest rail loops on Earth, and Tokyoites use it as the city's informal centre marker — "inside the Yamanote" means central Tokyo.

Distance is a poor proxy for journey time

Tokyo has the world's most efficient urban rail. A 10 km journey on the Yamanote Line takes about 18 minutes; the same 10 km between two private lines that don't connect can take 60 minutes with two transfers. For Tokyo work, rail-aware journey planners beat radius maps after the first 2–3 km.

Bay water bites only on the south and east

Tokyo Bay sits to the south and east of the city. A radius drawn from Shinjuku reaches mostly land in three directions (north, west, central), with only the southern and eastern arcs cut by water. This makes Tokyo radii feel "fuller" than NYC or San Francisco radii of the same size.

FAQ — Radius mapping in Tokyo

How big is a 5 km radius in Tokyo?

A 5 km radius from Shinjuku Station covers most of the Yamanote Line interior — Shibuya, Harajuku, Roppongi, Akasaka, the Imperial Palace, Akihabara, and Tokyo Tower. It captures the political, commercial, and entertainment cores of central Tokyo.

What's within 10 km of Tokyo?

A 10 km radius from Shinjuku extends well past the Yamanote Line into Setagaya, Suginami, Sumida, Koto, and most of the 23 special wards. Tokyo Skytree sits right at the eastern edge (~10 km); Haneda Airport is about 17 km south, well outside.

What is the Yamanote Line and how does it relate to a Tokyo radius?

The Yamanote is a 34.5 km circular train route around central Tokyo with 30 stations. It traces what Tokyoites consider "central Tokyo" and serves as the city's informal radius marker — about 5 km in radius from any of its central stations like Shinjuku or Shibuya.

Does a 25 km radius cover Tokyo Disneyland?

Yes. Tokyo Disneyland sits in Maihama (Chiba prefecture) about 18 km east of Shinjuku, comfortably inside a 25 km radius. Haneda Airport (~17 km south) and the inner edges of Yokohama and Kawasaki are also inside.

How much of Greater Tokyo fits inside a 50 km radius?

About 30 million people — roughly 80% of Greater Tokyo's 37 million-person metropolitan population. The 50 km radius covers all 23 special wards plus most of Yokohama, Kawasaki, Saitama, and west-Chiba. Narita Airport (60 km east) and Mt Fuji (100 km southwest) are outside.

Why is distance a poor proxy for travel time in Tokyo?

Because Tokyo's rail network is so dense and fast that direct lines collapse distance, while indirect routes balloon it. A 10 km journey on the Yamanote takes about 18 minutes, but a 10 km journey across two unconnected private lines can take an hour with transfers. Always pair radius with a rail-aware journey planner for Tokyo.
