Close to Tokyo, a world away
One of Izu’s great advantages is how easy it is to reach. The peninsula lies southwest of Tokyo along the Pacific coast, close enough for a long weekend yet far enough in feel to be a genuine escape. The eastern shore — the Kawana and Itō area this guide focuses on — is the most accessible part, reachable by train in around two hours from central Tokyo. General route planning is well served by Japan’s official travel site.
By rail from Tokyo
Rail is the natural way in. Trains run down from Tokyo along the coast, with limited-express services making the run comfortably and local trains covering the same ground more slowly and cheaply. The gateway city of Itō is the point where the mainline coast meets the peninsula’s own scenic railway, and for most itineraries it is where an Izu trip effectively begins. If you are travelling widely in Japan, check whether a rail pass covers part of the route before buying individual tickets.
The scenic coastal line
South of Itō, the railway hugs the shore on one of Japan’s prettier coastal lines, ducking through tunnels and bursting out to sea views as it links the eastern towns. Riding it is a pleasure in itself, and it makes car-free travel entirely practical along the developed eastern coast: you can base yourself in one town and day-trip up and down the line to beaches, viewpoints, and baths. Sit on the sea side of the carriage if you can.
Getting around once you arrive
Within the eastern towns, most of what a visitor wants — baths, harbours, restaurants, and the paths up Komuroyama — is close together and manageable on foot or with short local hops by train or bus. A car adds freedom for reaching remote coves, inland wasabi country, and hillside mikan orchards that public transport reaches awkwardly, but it is not necessary for a first, coast-focused trip. Decide based on how far off the main line you intend to wander.
Planning notes
A few practicalities smooth an Izu trip. Weekends and holidays — especially the cherry-blossom weeks and the summer swimming season covered on our seasons page — are busier, so midweek travel is calmer and easier. Many traditional inns expect an early evening arrival because dinner is part of the stay, as our ryokan tradition page explains, so plan the last leg of the journey to arrive in good time. And build in slack: Izu rewards the traveller who leaves room to linger by the water rather than racing a schedule.
A few practical odds and ends
Japan rewards a little preparation. Cash is still useful in smaller towns and at farm stands, though cards and IC transit passes work widely; an IC card tapped at the gate is the easiest way to ride local trains and buses. Coin lockers at the main stations let you explore unencumbered before check-in. Mobile coverage is good along the developed coast but can thin in the hills, so download maps before heading inland to the wasabi and mikan country. And pack light: inns provide yukata, towels, and toiletries, so an overnight bag is genuinely all you need for a night or two on the coast.
The short version
Take the train from Tokyo to Itō, continue along the scenic coastal line to your chosen town, and travel light and unhurried once you arrive. Time the visit to the season you most want, arrive early enough to enjoy the evening bath and meal, and let the coast set the pace. That is very nearly all the logistics an Izu trip requires.
