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.
The Yamanote Line — a rail loop around central Tokyo — works well as an informal radius marker. A 5 km radius from Shinjuku Station reaches Shibuya (~3 km south), Tokyo Tower (~5 km southeast), and stops short of Tokyo Station (~6 km east); a 10 km radius takes in Tokyo Station and Akihabara (~7 km east). For commute and travel-time analysis, distance is a poor proxy for journey time without rail-aware tools. Distances here are straight-line from Shinjuku Station — the same way the radius map measures them.

The Yamanote Line forms a rail loop around central Tokyo. A 5 km radius from Shinjuku Station reaches Shibuya (~3 km south) and Tokyo Tower (~5 km southeast), covering much of the dense core that loop encloses.
Also known as: Tōkyō, 東京, Edo (historical).
Coverage at common radii, including notable places that fall just outside the circle. Use these as a quick reference — check exact boundaries before relying on a circle for real-estate, retail, or service-area decisions.

A 1 km radius from Shinjuku Station reaches Kabukicho (~1 km north) and the edge of Shinjuku Gyoen (~1 km southeast), covering the entertainment and retail concentrations immediately around the station.
A 5 km radius from Shinjuku reaches Shibuya (~3 km south), with Tokyo Tower just beyond (~5.3 km southeast), covering much of central Tokyo's commercial and entertainment core. Tokyo Station (~6 km east) and Akihabara (~7 km east) fall just outside.
A 10 km radius from Shinjuku takes in Tokyo Station (~6 km east), Akihabara (~7 km east), and much of the central wards. Haneda Airport and Tokyo Disneyland both sit about 17 km out, just beyond this ring.
A 25 km radius from Shinjuku reaches well beyond the central wards, taking in Haneda Airport (~17 km southeast), Tokyo Disneyland (~17 km east), and almost to Yokohama (~26 km south).
A 50 km radius reaches deep into the surrounding region, comfortably covering Yokohama (~26 km south). Hakone (~83 km southwest) and Mt Fuji (~95 km west) remain well outside.
City-specific scenarios where a radius is the right tool — and a sensible radius to start with.
A 5 km radius from a major Tokyo workplace is a quick way to visualise the dense core around it. Journey time depends sharply on which line, not just straight-line distance — so pair the circle with a rail-aware journey planner.
Suggested starting radius: 5 km for Yamanote-aligned commute
To study foot-traffic overlap for convenience stores (konbini) or department-store food halls (depachika), draw a tight radius around a storefront. A 0.2–0.5 km circle maps the immediate walk-up catchment; a 1 km radius shows where nearby shops compete for the same pedestrians.
Suggested starting radius: 0.2–0.5 km for ultra-local retail
Tokyo Disneyland sits about 17 km east of Shinjuku and Haneda Airport about 17 km southeast, both inside a 25 km radius from central Tokyo. A 25 km circle is a handy way to define "Tokyo-area attraction reach" for one-day itineraries and hotel searches.
Suggested starting radius: 25 km for Tokyo attraction-area itineraries
A 50 km radius from Shinjuku stretches across the surrounding prefectures and takes in Yokohama (~26 km south). It is a useful starting circle for retail-chain expansion planning, service-area mapping, and B2B addressable-market estimates across the Kanto region — overlay your own population data to size it.
Suggested starting radius: 50 km for regional market sizing
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 circular train route around central Tokyo. Tokyoites use it as the city's informal centre marker — "inside the Yamanote" means central Tokyo.
A short hop on a direct line can be far quicker than a straight-line-shorter trip that requires two transfers between unconnected private lines. For Tokyo commute work, rail-aware journey planners beat radius maps after the first few kilometres.
Tokyo Bay lies to the south and east of Shinjuku. Draw a large radius and part of its southern and eastern arc may fall over water rather than land — worth keeping in mind when a circle is meant to capture population or catchment.
A 5 km radius from Shinjuku Station reaches Shibuya (~3 km south) and Tokyo Tower (~5 km southeast), capturing much of the commercial and entertainment core of central Tokyo. Tokyo Station (~6 km east) falls just outside.
A 10 km radius from Shinjuku takes in Tokyo Station (~6 km east) and Akihabara (~7 km east), along with the central wards. Haneda Airport (~17 km southeast) and Tokyo Disneyland (~17 km east) sit just beyond this ring.
The Yamanote is a circular train route around central Tokyo. It traces what Tokyoites consider "central Tokyo" and works as the city's informal radius marker — a 5 km radius from Shinjuku reaches Shibuya and Tokyo Tower inside that loop.
Yes. Tokyo Disneyland sits about 17 km east of Shinjuku, comfortably inside a 25 km radius. Haneda Airport (~17 km southeast) is also inside; Yokohama (~26 km south) falls just outside.
A 50 km radius from Shinjuku covers Yokohama (~26 km south) and stretches across the surrounding prefectures. Hakone (~83 km southwest) and Mt Fuji (~95 km west) remain well outside it.
Because a trip on a direct line can be far quicker than a straight-line-shorter trip that needs two transfers between unconnected private lines. Always pair a radius with a rail-aware journey planner for Tokyo.
