Introduction
Tokyo Metropolis (Tōkyō-to) is far larger than the neon city most visitors picture. It bundles the 23 special wards — the world's largest urban core, home to 14 million people — with the Tama region of western Tokyo, where forested mountains, river gorges and Mount Takao begin within an hour of Shinjuku, and with two island chains stretching nearly 1,000 kilometres into the Pacific: the volcanic Izu Islands, and the Ogasawara (Bonin) Islands, a UNESCO World Heritage site so isolated it is reached only by a 24-hour ferry and so evolutionarily distinct it is called the Galápagos of the Orient. The result is a single prefecture that runs from the busiest railway station on earth to subtropical reefs where humpback whales calve, and from three-Michelin-star sushi counters to family-run minshuku on islands where the only traffic is the morning fishing fleet.

Discover Tokyo

The 23 special wards (ku) form the dense heart of Tokyo and contain almost everything first-time visitors come to see. Each ward is effectively a city in its own right with its own character: Chiyoda holds the Imperial Palace and its moats at the literal centre; Chūō contains Ginza's luxury and the Tsukiji outer market; Shibuya and Shinjuku drive youth culture, nightlife and the skyscraper skyline; Taitō preserves old Edo around Senso-ji and Ueno's museum park; Minato gathers Roppongi's art and the Tokyo Tower. Moving between them is effortless thanks to the world's most intricate rail network — JR's Yamanote loop line strings together most of the major hubs, and the Tokyo Metro and Toei subways fill in everything between. The wards reward both the headline sights and aimless wandering: a back-street izakaya alley under the train tracks at Yūrakuchō, a craft coffee roaster in a Kuramae warehouse, a rooftop garden above a department store. For the full district-by-district guide, see the Tokyo city page — this prefecture overview points the way beyond the wards.

Travel Types

Metropolis & City Culture

Base yourself in the 23 wards for Shibuya and Shinjuku's energy, Asakusa's old-Edo temples, Ginza's luxury and the world's deepest concentration of restaurants, museums and nightlife — then use Tokyo's rail network to range across the whole prefecture. The wards alone hold more Michelin stars than any city on Earth and a transit system that runs on seconds.

Mountains & Day Hikes

Climb Mount Takao's pilgrimage trails 50 minutes from Shinjuku for tengu shrines and a winter Mount Fuji view, hike the Okutama valley's gorges and the Nippara Limestone Caves, and stay overnight in a pilgrim lodge on sacred Mount Mitake. Western Tokyo's forests, rivers and reservoirs are an easy escape from the urban core.

Islands & Beaches

Take an overnight ferry to the Izu Islands for black-sand beaches, surf, crater hikes on Ōshima's Mount Mihara and free seaside onsen on Niijima — all still officially Tokyo. Hachijōjima adds subtropical greenery and diving for travellers willing to go a little further south into the Pacific.

Wildlife & Marine Nature

Commit to the 24-hour ferry to the UNESCO-listed Ogasawara Islands for swimming with spinner dolphins, coral diving and year-round whale watching among species that exist nowhere else on Earth. Closer to the city, the Izu Islands offer reef snorkelling and birdlife in a far shorter trip.

Hot Springs & Onsen

Soak at Takaosan Onsen beside the trailhead after a mountain climb, bathe in tidal rock pools on Shikinejima, and watch the Pacific from Ōshima's open-air Hama-no-yu or Niijima's amphitheatre-shaped Yunohama. The prefecture's volcanic geology gives its mountains and islands a hot-spring culture the city core lacks.

Festivals & Seasonal Tokyo

Time a visit to the Sanja Matsuri in May, the Sumida River Fireworks in July, cherry blossoms along the Meguro River and in Shinjuku Gyoen in early April, or the maple blaze on Mount Takao in November. Tokyo Metropolis follows the seasons as closely as the calendar, and a peak moment transforms the experience.

Essential Tokyo Metropolis Travel Tips
  • •The 23 wards are best navigated with a Suica or Pasmo IC card — it works across JR, Tokyo Metro, Toei subway, buses and convenience stores. The JR Pass covers JR lines (including the Yamanote loop) but not the metro or private railways, so it is rarely worth it for a wards-only stay.
  • •Reaching the islands needs advance planning. The Izu Islands run on overnight ferries from Takeshiba pier and small flights from Chōfu; the Ogasawara Islands are served only by the weekly Ogasawara Maru ferry (about 24 hours each way), so a visit there is a six-day minimum — book a berth well ahead, especially in summer.
  • •Once you leave the wards, carry cash. Mountain villages in Okutama and businesses on the Izu and Ogasawara Islands are frequently cash-only, and ATMs that accept foreign cards are scarce outside the city. 7-Eleven and post-office ATMs in central Tokyo are your last reliable top-up.
  • •Mount Takao is genuinely crowded on autumn-foliage weekends in November and during cherry-blossom season — start early, or choose one of the steeper, quieter numbered trails over the paved Trail 1 if you want solitude. Sturdy shoes are enough; this is a forest walk, not an alpine climb.
  • •Cherry blossom (late March–early April) and autumn foliage (mid–late November) are peak periods across the prefecture: hotel prices rise, popular spots fill, and accommodation should be booked months ahead. The islands have their own season — summer for beaches and water, winter for whales and camellias.
  • •Tokyo is one of the safest major regions on Earth, with very low crime even late at night. The main practical hazards are summer heat and humidity (July–August can exceed 35°C — hydrate and pace temple-and-mountain days) and the rush-hour crush on wards trains between roughly 8 and 9:30 AM.
  • •Earthquakes are a fact of life and buildings are engineered for them; download the free 'Safety Tips' app for English-language alerts. Typhoon season runs June–October and can disrupt island ferries and flights for days, so build buffer time into any island itinerary.
  • •English signage is good in the wards and at major stations and has improved sharply since 2020, but it thins quickly in the mountains and on the islands. A translation app and a few basic phrases (sumimasen, arigatō gozaimasu) go a long way once you leave the centre.
  • •Day trips multiply easily from the wards: Mount Takao (under an hour), Okutama (about two hours), plus nearby destinations outside the prefecture such as Kamakura, Nikkō and Hakone. The Shinkansen from Tokyo Station puts Kyoto and Osaka within easy reach for longer loops.
