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.

    The shrine forest beside Harajuku Station creates a quiet break between Yoyogi Park, Takeshita-dori fashion crowds, and Omotesandō shopping. It works best early before school groups and weekend cosplay traffic build.

Neighborhoods

  • Shinjuku in tokyo jp1

    Shinjuku

    Shinjuku is a transport machine, nightlife district, and hotel base in one: the station, Tokyo Metropolitan Government towers, Kabukichō, Golden Gai, and department-store basements all stack together.

  • Shibuya, Harajuku & Ebisu in tokyo jp2

    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.

  • Ueno, Asakusa & Taito in tokyo jp3

    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.

  • Ginza, Nihonbashi & Tsukiji in tokyo jp4

    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.

  • Chiyoda, Marunouchi & Akihabara in tokyo jp5

    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.

  • Minato, Roppongi & Odaiba in tokyo jp6

    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.

City overview

Seoul is a Han River capital split between Gangbuk, the Joseon-era north with palaces and markets, and Gangnam, the newer south with towers, malls, and business districts. The city has no single tourist centre: Jongno and Jung carry Gyeongbokgung, Bukchon, Myeongdong, Namdaemun, and Namsan, while Hongdae, Itaewon, Gangnam, and Songpa each behave like their own downtown.

Food & drink

Seoul is built around barbecue, soups, and late-night snacks: samgyeopsal, bulgogi, bibimbap, tteokbokki, Korean fried chicken, dakgalbi, bingsu, and gimbap all have easy first-trip versions. Myeongdong and Gwangjang Market are central snack anchors, Hongdae and Sinchon run late, Itaewon handles international food, and Michelin Bib Gourmand-style pricing sits beside expensive Gangnam tasting counters.

  • Yongsan & Itaewon in seoul kr4

    Yongsan & Itaewon

    Yongsan gives international restaurants, Itaewon bars, Leeum Museum, and easy jumps to Namsan or the Han River. It is the city's clearest foreign-food and nightlife pocket.

  • Gangnam & Seocho in seoul kr5

    Gangnam & Seocho

    Gangnam and Seocho are the high-rise south: COEX Mall, business hotels, clinics, clubs, and broad boulevards. Distances look short on maps but subway exits and crossings add time.

  • Songpa & Jamsil in seoul kr6

    Songpa & Jamsil

    Songpa is the family-entertainment and sports district, with Lotte World, Lotte World Tower, Seokchon Lake, Olympic Park, and Jamsil Sports Complex clustered east of Gangnam.

Getting around

Seoul Subway lines cover nearly every visitor district, and T-money cards work across subway, buses, taxis, and convenience stores. AREX links Incheon Airport to Hongdae and Seoul Station in about an hour, while palace-core days are fastest by walking between Gwanghwamun, Bukchon, Insa-dong, and Cheonggyecheon rather than re-entering the subway for one stop.
