Visiting the Izu Peninsula: Sights, Seasons and Getting Around
Izu is a peninsula of hot springs and scenic coastline in Shizuoka, reachable from Tokyo in half a day. This guide covers who it suits, how many days, when to go and what to see.
Quick answer
- It suits people wanting onsen and a relaxed coastal trip; allow at least 2 days and 1 night.
- Known seasons are early cherry blossom at the end of winter, autumn leaves late in the year, and sea weather in summer.
- The hardest part is reaching coastal spots far from stations; a rental car or buses need planning.
Izu suits people who want to leave the city without travelling far from Tokyo. The peninsula packs onsen towns, old harbour towns, coastal cliffs, waterfalls and small volcanoes into a not-very-large area. But moving around the peninsula is slower than the map suggests, because coastal roads wind and only a few rail lines serve it. This article is an overview to help you choose which zone to visit first.
Who it suits and how many days
A short 2-day, 1-night trip suits people who want one onsen night and one zone, for example Ito with the Jogasaki coast, or Shuzenji. With 3 to 4 days you can reach Shimoda in the south and a few western spots. What does not work is trying to see the whole peninsula in a day, because you spend more time in transit than at sights. Outdoor lovers, families and couples tend to like it; those wanting shopping or lively nightlife are better off choosing Tokyo.
Best months and weather
The best-known season is late winter into early spring, when the early-blooming Kawazu cherry trees flower in Kawazu town and draw many visitors. The actual bloom timing changes each year, so watch the official announcements before booking. Late-year autumn brings colour in valleys and inland onsen towns. Summer is beach season around Shimoda and the bays, but it is hot, humid and subject to seasonal rain. Snow on the coastal lowlands is rare; winter cold here is mostly sea wind and damp rather than deep snow.
Getting there and around
From Tokyo, the Odoriko limited express runs directly to several Izu towns, and you can also take the Tokaido Shinkansen to Atami or Mishima and change trains. Inside the peninsula, the Izukyu line serves the east coast from Ito south to Shimoda, and the Izuhakone Railway runs from Mishima to Shuzenji. The west coast and southern cape depend mainly on buses or cars. Frequencies, timetables and tickets change with the season, so check with the operators.
Main sights
- Jogasaki Coast near Ito: lava cliffs and a suspension bridge by the sea
- Shuzenji Onsen: an old onsen town and a bamboo grove path
- Shimoda: a historic port town with fine beaches to the south
- Kawazu: early cherry blossom and the Nanadaru waterfalls
- Dogashima on the west coast: rock formations and Suruga Bay views
Jogasaki is a coastline formed by volcanic lava, ideal for a short walk on paths beside the sea. Shuzenji can be covered on foot in half a day, with a temple, bridges and a bamboo path. Shimoda is tied to the history of Japan opening to the outside world, with an old town and beaches popular in summer. The sights are far apart, so do not pick more than two or three in a day.
Quieter sights and hidden gems
To avoid crowds, look for smaller places such as Joren Falls in central Izu, headlands such as Irozaki at the southern tip, which is quieter than the main towns, and small beach villages on the west coast. Some have little public transport, so you need a car. Quiet does not mean fully serviced, so carry water and some cash, and check access hours before going.
Rainy days, evenings and free options
On rainy days switch to indoor options such as soaking in an onsen, small museums, seafood markets and cafes in the onsen towns. Evenings in Izu are quieter than in big cities, mostly dinner at the inn, an onsen soak and a stroll along the station street. Free attractions are usually coastlines, seaside walks, some shrines and public viewpoints, though you still need to check access conditions and hours at each.
When you combine trains and buses in an area where English signage is limited, an online phone lets you check routes, timetables and boarding points on the spot. A Japan eSIM can be activated before departure, so there is no need to look for a SIM or Wi-Fi at the station.
Short plan and practical notes
- Day 1: arrive in Ito or Atami, visit Jogasaki and check in to an onsen inn
- Day 2: take the Izukyu line south to Kawazu or Shimoda depending on the season
- Day 3: return to a major city by the most convenient route
Key points: book accommodation early for cherry blossom season and long holidays, pack a small bag if you change trains several times, and leave a safe margin for returning to Tokyo before a flight or next engagement. If you plan many stops, consider a rental car, but those unused to driving on the left should stay with public transport.
