How many days do you need on the Izu Peninsula?
Two to three nights. Two nights lets you pick one coast and do it well: take the Odoriko down to Shimoda for beaches and seafood, or base in Ito for the Jogasaki cliff walk and east coast onsen. Three nights gives you time to cross between the east coast and the interior, which means you can add Shuzenji without rushing.
A single night works if you're only doing Atami (closest to Tokyo, about 45 minutes on the Shinkansen) or Shuzenji. But one night misses the coastline, and the coastline is what separates Izu from Hakone. If all you want is an onsen overnight near Tokyo, Hakone is easier. Izu rewards the extra day.
If you're combining Izu with a broader Greater Tokyo trip, budget the peninsula as its own 2-to-3-day block. It doesn't combine well as a day trip from Tokyo. The train ride is long enough that you'd spend half the day in transit and only scratch one town.
Where should you stay on the Izu Peninsula?
It depends on what you're here for. Izu isn't one place; it's four towns spread across a mountainous peninsula, each with a different character. You'll want to pick a base, not try to see them all.
Ito is the best base for the east coast. It's where you stay for the Jogasaki cliff walk, and the town has a solid range of onsen hotels at mid-range prices. It's also the last station covered by the JR Pass, so if you're using a regular JR Pass, this is your stop. Ito feels like a proper hot spring town without being overly polished.
Shimoda is the pick for beaches and seafood. It's the furthest south, about 2 hours 50 minutes from Tokyo on the Odoriko, and it has the best kinmedai on the peninsula. The white-sand beaches and Perry Road give it a different feel from the other towns. It's more of a coastal destination than a hot spring destination, though onsen are still easy to find.
Shuzenji is the traditional option. A small onsen town in the interior with a bamboo grove, a temple, and ryokan along the Katsura River. It's the quietest of the four and the one that feels most like a classic Japanese onsen town. You reach it from Mishima on the Izuhakone Railway, not from the east coast line, so plan it as a separate trip.
Atami is closest to Tokyo (about 45 minutes on the Shinkansen) and has the most hotel options. It went through a long decline as a resort town but has come back in recent years with new shops and renovated ryokan. Atami works as a quick overnight, but it's more urban than the other towns. If you want the coastal or traditional onsen experience, keep going south.
What should you do on the Izu Peninsula?
The Jogasaki Coast near Ito is the headline. It's a cliff-edge hiking trail along volcanic rock, with suspension bridges hanging over the ocean and views down the coastline. The full trail takes a few hours, but shorter sections work if you just want the bridges and the views. It's one of the best coastal walks near Tokyo, and it never gets the foot traffic that trails in Hakone or Kamakura do.
In Shimoda, the beaches are the draw. Shirahama Beach (literally "white sand beach") is the most popular (and busiest in summer), but the smaller coves nearby are quieter. Perry Road, the canal-side street that Commodore Perry walked to reach Ryosenji Temple for the 1854 treaty signing, has been preserved as a café-lined walking street. It's a 20-minute stroll, not a half-day attraction, but it gives Shimoda a historical layer the other towns don't have.
Shuzenji is about slowing down. The bamboo grove is a short walk from the main temple, and the whole town loops along a single river with footbridges and small onsen. You walk between baths in yukata, eat at the ryokan, and that's the point. It doesn't need a packed itinerary.
The Kawazu Seven Waterfalls (Kawazu Nanadaru) are on the east coast between Ito and Shimoda. It's a half-day hike through a gorge with seven falls connected by a walking trail. Good for a morning if you're basing in either town.
Hot springs are everywhere. Every town on the peninsula has public onsen or ryokan baths. Izu doesn't have one famous bathhouse the way Kusatsu has its yubatake; instead, you pick a town and the onsen are built into wherever you stay.
The honest downside: getting between towns without a car is slow. Buses exist but run infrequently, especially along the west coast. If you're relying on trains and buses, you'll likely stick to one coast per trip. A rental car changes the equation entirely and opens up the west coast, which has some of the best ocean-view onsen on the peninsula.
How do you get to the Izu Peninsula?
For the east coast (Ito, Shimoda): The Odoriko limited express runs from Tokyo Station to Izukyu-Shimoda. About 2 hours 50 minutes end to end, around ¥5,000 to ¥5,500. It stops at Atami and Ito along the way, so you can get off earlier if that's your base. The Saphir Odoriko is the luxury version of the same route: Green Class seats, about ¥10,060 to Shimoda, roughly 2.5 hours.
For Shuzenji: Take the Shinkansen from Tokyo to Mishima (about 55 minutes, around ¥3,740), then transfer to the Izuhakone Railway to Shuzenji (about 35 minutes). It's a completely separate line from the east coast, so don't try to combine Shuzenji and Shimoda in one linear route.
Alternative route: Shinkansen to Atami (about 45 minutes), then transfer to the JR Ito Line southbound. This is faster to Atami and Ito than the Odoriko but requires a transfer.
| Route | Time | One-Way Cost |
|---|---|---|
| Tokyo → Shimoda (Odoriko) | ~2 hrs 50 min | ~¥5,000–5,500 |
| Tokyo → Shimoda (Saphir Odoriko) | ~2.5 hrs | ~¥10,060 |
| Tokyo → Atami (Shinkansen) | ~45 min | ~¥3,740 |
| Tokyo → Shuzenji (via Mishima) | ~1 hr 30 min | ~¥4,500 |
Rail pass notes: The regular JR Pass covers the route only as far as Ito. From Ito to Shimoda, you're on the Izukyu Railway, which costs an extra ¥1,690 (local) or ¥2,490 (limited express supplement). The Tokyo Wide Pass (¥15,000 for 3 days) covers the full route to Shimoda, including the Izukyu section, and pays for itself on one round trip from Tokyo.
Getting around the peninsula: Trains run along the east coast from Atami to Shimoda. Buses connect towns but run infrequently, sometimes once an hour or less. The west coast has almost no public transit. If you're planning to move between coasts or explore beyond the train line, a rental car is the practical choice. Pick one up in Atami or Ito.
How much does the Izu Peninsula cost?
| Category | Budget | Mid-Range | Splurge |
|---|---|---|---|
| Accommodation | ¥6,000 | ¥12,000–20,000 | ¥30,000+ |
| Food | ¥2,000–3,000 | ¥4,000–6,000 | ¥10,000+ |
| Transport (local) | ¥500 | ¥1,000 | ¥3,000 (car rental) |
| Activities | ¥0–500 | ¥1,000 | ¥2,000 |
| Daily Total | ~¥8,500–10,000 | ~¥18,000–27,000 | ~¥45,000+ |
The big variable is accommodation. A budget hotel in Atami or Ito runs around ¥6,000 per night. A mid-range ryokan with onsen and dinner included costs ¥12,000 to ¥20,000 per person. At the high end, ryokan with private outdoor baths and full kaiseki start at ¥30,000 per person and go up from there. Izu's ryokan pricing is similar to Hakone, and the reason is the same: you're paying for the bath, the view, and the dinner as a package.
Food outside the ryokan is reasonable. A kinmedai set meal in Shimoda runs ¥1,500 to ¥2,500 at most places. Kaisendon (seafood bowls) along the east coast are in the same range. The splurge is at the ryokan dinner table, not at standalone restaurants.
Most attractions on Izu are free or nearly free. The Jogasaki cliff walk costs nothing. Beaches are free. Shuzenji's temple and bamboo grove are open to walk through. The money goes to the ryokan, the fish, and the train ride down.
What should you eat on the Izu Peninsula?
Kinmedai (golden-eye snapper). This is THE fish of Izu, and Shimoda is where you eat it. The classic preparation is nitsuke, simmered in a sweet soy glaze until the skin goes glossy and the flesh pulls apart. You'll find it as sashimi too, but the nitsuke is the local move. A kinmedai set meal at a restaurant near Shimoda's harbor runs ¥1,500 to ¥2,500, which is less than you'd pay for the same fish in Tokyo.
Izu is the birthplace of wasabi. The mountain streams on the peninsula are where wasabi cultivation started, and you'll taste the difference between freshly grated wasabi here and the tube paste served everywhere else. It comes with sashimi, on soba, and at wasabi farms in the interior where you can grate your own.
The east coast has good general seafood: sashimi platters, kaisendon (rice bowls piled with raw fish), and grilled fish at harbor-side spots in Ito and Shimoda. It's not Tsukiji levels of variety, but the fish is coming straight off the boats, and the prices reflect that you're eating at the source.
If you're staying at a ryokan, the kaiseki dinner is likely included in your room rate. At mid-range and above, that dinner will feature kinmedai, local sashimi, and seasonal dishes. It's one of the few places near Tokyo where the ryokan dinner alone justifies the price of the room.
When is the best time to visit the Izu Peninsula?
Izu works year-round, and the coastal climate keeps it milder than Tokyo in both directions. Winters are warmer, summers slightly less brutal. It's a peninsula surrounded by ocean, and you can feel it in the air.
Late January to February is the standout season. The Kawazu cherry blossoms along the Kawazu River bloom weeks before anywhere else in the Tokyo region. If you want cherry blossoms without fighting for space under the trees in Ueno or Meguro, this is your window. The early bloom draws crowds to Kawazu itself, but the rest of the peninsula stays quieter.
Autumn and winter (October to February) are the best months for onsen. Fewer crowds, cooler air, and ryokan rates drop outside the holiday periods. The Jogasaki cliff walk is still comfortable in November. Winter is when Izu feels most like what it is: a hot spring coast where you soak, eat fish, and don't do much else.
Summer (July to August) is beach season. Shimoda's beaches fill up with weekenders from Tokyo, especially Shirahama. It's the only time Izu gets genuinely crowded. The humidity is real, but you're on the coast, so the ocean and the onsen take the edge off.
Spring (March to April) brings the regular cherry blossoms (after Kawazu's early bloom is already finished) and comfortable hiking weather for the Jogasaki Coast.
The thing that surprises people about Izu is how few foreign visitors go there. Japanese weekenders know the peninsula well, especially the onsen and the seafood. But it stays off most international itineraries because Hakone is closer and more famous. That's exactly why the towns feel unhurried, the English signage is minimal, and the ryokan prices haven't inflated the way Hakone's have. It's the longer train ride that keeps it that way.
