Welcome to Izu Islands

The Izu Islands, a volcanic archipelago stretching south from Tokyo into the Philippine Sea, offer a world apart from Japan's frenetic mainland. Administered as part of Tokyo Metropolis, these nine inhabited islands are a sanctuary of dramatic coastlines, smoldering volcanoes, dense forests, and onsen hot springs. Each island possesses a distinct character, from the rugged, active volcano of Oshima to the subtropical, palm-fringed shores of Hachijojima. This is a destination for adventurers, nature lovers, and those seeking a profound sense of escape, where the rhythms of the ocean and the earth dictate the pace of life. With around 20 hotels scattered across the islands, providing an average nightly stay of just over $97, visitors can find comfortable lodgings that range from simple minshuku guesthouses to modern resorts, serving as perfect bases for exploration. A recommended stay of one day per major island allows for a taste of their unique offerings, though many find themselves wishing for more time immersed in this raw, beautiful landscape.

Overview

The Izu Islands are a chain of over a dozen volcanic islands, part of the Fuji-Hakone-Izu National Park. Historically, they served as places of exile and penal colonies, most famously during the Edo period, which shaped a resilient and independent local culture. Today, they are celebrated for their geothermal activity, pristine marine environments, and as a getaway for Tokyo residents. The islands are famous for their active volcanoes, notably Mount Mihara on Oshima, which last erupted in the 1980s. Culturally, they blend mainland Japanese traditions with unique island festivals, such as Oshima's Toshidon New Year's ritual. The main islands for tourism include Izu Oshima (the largest, known for its volcano and camellias), Hachijojima (famous for its hiking, beaches, and former exile history), and Miyakejima (notable for its post-eruption return and unique 'gas mask' hiking tours). The islands' economy revolves around fishing, tourism, and unique agricultural products like Hachijo Island's kihachi citrus and kusaya fermented fish.

🗓️ Best Time to Visit

The best time to visit the Izu Islands is during the late spring (May to June) and autumn (September to October) shoulder seasons. These periods offer mild, comfortable temperatures, lower humidity, and generally clear skies ideal for hiking and outdoor activities. The summer months (July to August) are the peak tourist season, coinciding with Japanese school holidays; the weather is warm to hot and humid, perfect for beach activities on islands like Hachijojima, but also bringing higher prices and crowds. This season also carries a higher risk of typhoons. Winter (December to February) is the off-peak season, with cooler temperatures and fewer visitors, offering a serene experience, though some tourist facilities may have reduced hours. Major events include the Oshima Camellia Festival (January-March), the Hachijo Island Marathon (March), and vibrant summer festivals (matsuri) on each island featuring fireworks and traditional dances. Whale watching is best from January to April around the islands.

🌤️ Weather & Climate

🚗 Getting Around

Transportation varies significantly between islands. Inter-island travel is primarily via ferry or high-speed jet foil from Tokyo's Takeshiba Terminal or Atami. Flights from Haneda Airport serve Oshima, Hachijojima, and Miyakejima. On the islands, public bus networks are the main form of transport but can be infrequent, especially on smaller islands. Renting a car, scooter, or bicycle is highly recommended for flexibility; rental agencies are available at ports and airports. Taxis are available but can be scarce and expensive. Walking is viable in small port towns but not for accessing major attractions like Mihara-yama volcano. Costs: Ferry tickets range from $30-$100+ depending on route and class. Island bus fares are typically $2-$5 per ride. Car rentals start around $50/day. Always check ferry and flight schedules in advance as they are weather-dependent.

🍽️ Local Cuisine

Izu Islands cuisine is defined by the bounty of the sea and volcanic soil. Signature dishes include kusaya (fermented and dried fish, a Hachijo specialty with a strong odor but prized flavor), ise-ebi (spiny lobster), fresh sashimi, and ashitaba (a hardy, nutritious green grown on Hachijojima, used in tempura, soba, and tea). Tuna and bonito are also staples. Dining culture is casual, centered on small local restaurants and izakayas in port towns. Must-try foods include shimazushi (island-style pressed sushi), seafood donburi bowls, and the local shochu. Popular food areas are the ports and fishing harbors on each island. Price ranges: Budget meals (ramen, donburi) from $8-$15, mid-range set meals from $15-$30, high-end seafood courses from $50+. Etiquette is standard Japanese: say "itadakimasu" before eating, don't stick chopsticks upright in rice, and try everything offered.

💡 Local Tips

Transportation
Always check ferry and flight schedules online before finalizing your itinerary, as services are reduced in winter and canceled in bad weather.
Transportation
Rent a car or scooter for maximum freedom, especially on larger islands like Oshima and Hachijojima, where bus services are limited.
Money
Carry plenty of cash (Japanese yen). While cards are accepted at some hotels, many smaller restaurants, shops, and guesthouses are cash-only.
Accommodation
Book accommodation well in advance for summer weekends and festival periods, as rooms fill quickly with domestic tourists.
Food
Try the local kusaya fish at least once. The smell is strong, but the taste is a unique, savory island tradition.
Safety
Respect volcano alert levels and never enter restricted zones. Volcanic gas can be dangerous.
Packing
Pack a small umbrella and rain jacket regardless of the season; weather can change rapidly.
Culture
Learn a few basic Japanese phrases. English is not widely spoken outside major tourist offices and hotels.
Planning
Visit the local tourist information center (kanko annaijo) at the port or airport for the latest maps and advice.
Activities
If hiking, wear proper footwear, bring ample water, and have a offline map or GPS device.
Culture
Onsen etiquette is important. Wash thoroughly before entering the bath, and never wear swimwear (use a small towel for modesty).
Shopping
For a unique souvenir, buy ashitaba (tomorrow's leaf) products like tea, soba, or cookies from Hachijojima.
Etiquette
Take your trash with you. Public bins are rare; be prepared to carry waste back to your accommodation.
Mindset
Enjoy the slow pace. Island time is real; buses and ferries may not always be perfectly on schedule.
Food
For the best seafood, eat at restaurants near the fishing ports in the early afternoon when the day's catch comes in.
Transportation
If prone to seasickness, choose a jet foil over a standard ferry for a faster, smoother inter-island journey.
Connectivity
Mobile phone reception can be spotty in mountainous areas. Download offline maps and information beforehand.
Etiquette
Respect private property and farmland. Stick to marked trails and paths when exploring.
Health
In summer, apply sunscreen and insect repellent liberally, especially in forested and grassy areas.
Culture
Experience a local festival (matsuri) if your visit coincides. Check dates online or at the tourist office.

🛡️ Safety Tips

The Izu Islands are generally very safe with low crime rates. The primary safety concerns are natural: volcanic activity, typhoons, and strong ocean currents. Always check volcano alert levels and heed trail closures. Monitor weather forecasts for typhoons from July to October; ferries and flights are canceled during storms. When swimming, only use designated beach areas with lifeguards. There are no specific tourist scams, but standard vigilance with belongings is advised. Emergency numbers: Police (110), Fire/Ambulance (119). English-speaking operators may not be available, so ask your accommodation for help. Medical facilities are limited on smaller islands; carry necessary medications. Tap water is safe to drink. Be cautious when hiking alone; inform someone of your plans.
