The Izu Islands are a volcanic archipelago administered by Tokyo but located far from the capital’s crowded streets. Each inhabited island has its own landscape, access route and character—from active volcanic scenery on Izu Oshima to surfing on Niijima and remote nature on Mikurashima. Choosing the right island is more important than assuming all of them can be visited easily on the same day.
Key Takeaways

Highlights and Practical Advice
Which Izu Island should you choose?
Izu Oshima is one of the simplest introductions, with volcanic landscapes and a range of transport. Niijima appeals to surfing and island beach culture, while Shikinejima offers small coves and hot springs. Kozushima has mountain scenery and clear waters; Miyakejima and Mikurashima offer distinctly different volcanic and wildlife experiences. For related Singapore attractions, izu oshima island and niijima island; check each attraction’s own hours and transport routes.
Izu Oshima and Mount Mihara
Izu Oshima is the largest and among the most accessible islands. Mount Mihara is an active volcano whose trails and geological formations reveal the island’s origins. Only walk routes open under current hazard warnings, and never ignore volcanic-alert or weather notices. The island has cycling and coastal scenery as well. If you are planning other experiences, izu highland and enoshima; check each attraction’s own hours and transport routes.
Niijima, Shikinejima and Kozushima
These islands appeal to travellers who enjoy beaches, traditional onsen culture, diving and quiet local communities. Water activities depend heavily on swell and currents. Do not assume every beach has lifeguards or every outdoor hot spring is open in poor weather. Booking accommodation ahead helps on busy seasonal weekends. To compare places and travel styles, hachijo island hachijojima and miyake island miyakejima; check each attraction’s own hours and transport routes.
Miyakejima, Mikurashima and Hachijojima
These farther-flung destinations offer volcanic landscapes, forests, birds and ocean ecology. Miyakejima’s volcanic history deserves careful respect for safety advisories. Mikurashima is associated with marine life but wildlife encounter tours must follow conservation rules. Hachijojima is accessible by plane from Haneda as well as ship. For more visitor options, tokyo station and tokyo bay ferry; check each attraction’s own hours and transport routes.
How to Visit and What It Costs
Getting there by ferry from Tokyo
Takeshiba Passenger Ship Terminal serves many islands through Tokai Kisen, with high-speed and overnight passenger routes depending on destination. A boat route’s calling port and travel duration can change with weather. Carry essential medication and leave a buffer before a connecting international flight. For related cultural context, tokyo water buses and tokyo bay aqua line; check each attraction’s own hours and transport routes.
Flights and helicopter links
New Central Airservice flies from Chofu to selected islands such as Oshima, Niijima, Kozushima and Miyakejima. ANA serves Hachijojima from Haneda. Toho Air Service operates helicopter links among selected islands including remote Aogashima routes. These are small-capacity services, so reservations and luggage restrictions matter. A separate trip could include ogasawara islands and chichijima island; check each attraction’s own hours and transport routes.
Itinerary Ideas and Travel Safety
When is the best season?
Summer is popular for swimming but typhoons and rough seas can disrupt transport. Spring and autumn can suit hiking, while winter brings cool winds and fewer services or closed seasonal businesses. Even in sunny weather, high swell can cancel a ferry, so check the official Tokyo transport dashboard immediately before travelling. Other suitable destinations are tokashiki island tokashikijima and kouri island kourijima; check each attraction’s own hours and transport routes.
A practical three-night island itinerary
Choose one accessible island, such as Oshima, and spend a day exploring its main town, a day on geological trails and another on quieter coastal sights. If island-hopping, confirm onward connections rather than assuming daily boats between every pair. Leave sufficient contingency before returning to Tokyo. To plan a longer itinerary, consider tsushima island and amami oshima island; check each attraction’s own hours and transport routes.
How to Choose the Best Izu Island for Your Trip
| Island | Best known for | Practical planning point |
|---|---|---|
| Izu Oshima | Mount Mihara, volcanic geology, cycling | Relatively accessible by ferry or plane |
| Niijima | Surfing and beaches | Sea conditions can affect boat landing |
| Shikinejima | Small coves and onsen | Check inter-island ferry connections |
| Kozushima | Mountain scenery and clear water | Plan local transfers after arrival |
| Miyakejima | Volcanic scenery and nature | Review local volcanic safety notices |
| Hachijojima | Subtropical landscapes and hiking | Haneda flights provide an air option |
Ferry versus flight: the main trade-off
A jetfoil may offer a scenic trip without airport formalities, but rough seas can interrupt service at short notice. A flight saves travel time on some routes, yet small airports also experience wind-related cancellations and restricted baggage allowances. Check the exact island and travel date on the Tokyo Metropolitan Government’s island access service rather than relying on a single generic ‘Izu ferry’ timetable.
Seasonality and accommodation
Summer draws beach and diving visitors; accommodation can fill quickly around holidays. Spring and autumn suit walking but some marine services may still be seasonal. Winter travel can be quiet and rewarding if you are prepared for wind and ferry disruption. Book at least one overnight stay on your chosen island unless there is a confirmed day-trip route with a reliable return connection.
Volcanic safety and responsible nature travel
Several islands have volcanic landscapes. These are natural hazard environments, not unrestricted adventure playgrounds. Follow Japan Meteorological Agency notices and local exclusion zones, stay on signed routes, avoid unstable cliffs and never enter the sea under high-surf warnings. If your tour includes wildlife observation, choose operators who follow local conservation standards and keep a safe distance from marine animals.
