City overview

Tokyo is a rail-shaped metropolis where the JR Yamanote loop frames the old shogun centre, while Shinjuku, Shibuya, Ueno, Asakusa, Ginza, and Odaiba pull visitors into separate city-centres. The Sumida River, Tokyo Bay, and the former Edo castle grounds still organize the first-timer map even when the subway makes the city feel borderless.

Food & drink

Tokyo is one of the world's densest restaurant cities, with Edo-mae sushi, tempura, unagi, soba, ramen, tonkatsu, and Tsukishima monjayaki all tied to specific districts. Tsukiji Outer Market is the breakfast anchor, Ginza and Nihonbashi handle high-end sushi counters, Shinjuku and Ebisu cover izakaya nights, and the city has held more Michelin-starred restaurants than any other city in several guide years while still rewarding cheap station-counter meals.

1
Shibuya Crossing
4.5★ · 20,962outdoor
The scramble crossing outside Shibuya Station is a rail-node spectacle rather than a long sight. Pair it with Hachiko, Center-gai, Harajuku, or the Shibuya Sky side of the station.

2
Imperial Palace East Gardens
4.4★ · 9,958outdoorClosed Mon/Fri
The former Edo Castle site sits in Chiyoda inside the Yamanote loop, with moats, stone walls, and garden paths near Tokyo Station. The main palace remains closed except for limited public occasions, so the East Gardens are the everyday visit.

Tokyo Skytree & Sumida River
4.4★ · 114,578outdoorOpen daily
The 634-metre Skytree rises on the east side near Oshiage, giving the clearest aerial read of the Sumida River and central Tokyo spread. Combine it with Asakusa by walking or taking a short train hop.

Neighborhoods

1
Shinjuku
Shinjuku is a transport machine, nightlife district, and hotel base in one: the station, Tokyo Metropolitan Government towers, Kabukicho, Golden Gai, and department-store basements all stack together.
2
Shibuya, Harajuku & Ebisu
This west-side belt is youth fashion, crossings, music shops, cafes, and shrine forest. Shibuya and Harajuku bring the crowds; Ebisu is the calmer dinner-and-bar release valve.
3
Ueno, Asakusa & Taito
Taito keeps the old-town Tokyo feeling with Senso-ji, Ueno museums, Ameyoko, kitchenware streets, and Sumida River access. It is better for temples and markets than late-night skyscraper views.
4
Ginza, Nihonbashi & Tsukiji
Chuo is polished and expensive: Ginza stores, Kabuki-za, Nihonbashi department stores, and Tsukiji breakfasts sit on a gridded east-centre map.
5
Chiyoda, Marunouchi & Akihabara
Chiyoda mixes the Imperial Palace, Tokyo Station, Marunouchi offices, Jimbocho bookshops, and Akihabara hobby retail. It is the business core with sudden specialist pockets.
6
Minato, Roppongi & Odaiba
Minato covers embassies, Roppongi museums and nightlife, Tokyo Tower, Shiodome, and bayfront Odaiba. It is spread out, so rail-line choice matters more here than in Taito.

Getting around

Tokyo runs on JR, Tokyo Metro, Toei Subway, and private railways; Suica and PASMO IC cards remove fare math across almost all of them, while the Yamanote loop is the mental map for first-timers. Haneda is the closer airport, Narita is about 70km east, and subway fares in 2026 start around 180 yen with Tokyo Metro/Toei passes useful only on heavy subway-only days.
