Just 90 minutes from Tokyo by bullet train, the Izu Peninsula feels like a completely different world — rugged volcanic coastlines, steaming hot spring towns, hidden sea caves, and some of the freshest seafood you’ll ever taste. Yet despite being so close to Japan’s busiest metropolis, most visitors to Japan never make it past Atami. That’s their loss — and your opportunity.
Planning a Izu Peninsula 2 day trip from Tokyo can feel overwhelming at first. Do you rent a car or rely on trains? Should you base yourself in Shuzenji, Shimoda, or somewhere in between? Which beaches are actually worth visiting? And how much is all of this going to cost? If these questions are spinning in your head, you’re in exactly the right place.
In this guide, we’ve built a realistic hour-by-hour, two-day itinerary that balances iconic landmarks with hidden gems — plus honest cost breakdowns, accommodation comparisons across every budget, and the transport trade-offs no other guide wants to talk about. Whether you’re a solo traveler, a couple looking for a romantic onsen escape, or a small group chasing coastal adventure, this is the only Izu Peninsula weekend guide you’ll need in 2026.

Why Izu Peninsula Is the Perfect Tokyo Weekend Escape
The Izu Peninsula juts south into the Pacific Ocean from Shizuoka Prefecture, forming one of Japan’s most geographically dramatic coastlines. Shaped by volcanic activity, the peninsula is laced with onsen (hot spring) towns, sea-carved cliffs, turquoise coves, and lush forested mountains. Unlike the more commercialized resort areas closer to Tokyo, the southern tip around Shimoda still retains a genuine, unhurried charm.
For Tokyo-based travelers, Izu checks every box for a perfect weekend escape: it’s close enough to leave on a Friday evening and return Sunday afternoon, rich enough in attractions to fill two full days, and diverse enough to satisfy history buffs, beach lovers, foodie adventurers, and onsen enthusiasts alike. The peninsula is also famous as the landing site of Commodore Perry in 1854, giving it an unexpectedly rich layer of cultural and diplomatic history.
The best seasons to visit are spring (March–May) for cherry blossoms and mild temperatures, and early autumn (September–October) when summer crowds thin but the sea is still warm. Summer (July–August) is peak beach season — expect crowds and higher prices. Winter is quieter and perfect for onsen, though some coastal spots can be windswept.
• Avoid Golden Week (late April–early May) and Obon (mid-August) if possible — ryokan prices double and roads clog.
• The Izu Peninsula is roughly 60 km long, so plan your stops geographically to avoid backtracking.
• Book ryokans at least 4–6 weeks in advance for weekend stays, especially in spring and autumn.
How to Get to Izu from Tokyo (Trains, Routes & Travel Times)
The Odoriko Limited Express — Your Best Friend
The most comfortable and direct option is the Odoriko Limited Express, which runs from Tokyo Station directly down the eastern Izu coast, stopping at Atami, Ito, and continuing all the way to Shimoda. Journey times:
- Tokyo → Atami: approx. 50 minutes (~¥3,600 reserved seat)
- Tokyo → Ito: approx. 1 hour 30 minutes (~¥4,000)
- Tokyo → Shimoda: approx. 2 hours 20 minutes (~¥5,500)
JR Pass holders: The Odoriko is covered by the JR Pass for the sections running on JR tracks (Tokyo to Atami/Ito). However, the Izukyuko Railway section from Ito to Shimoda is NOT covered and requires a separate fare (¥1,680 one-way). Plan accordingly.
Shinkansen + Local Train Option
If you have a JR Pass, take the Tokaido Shinkansen from Tokyo to Atami (just 35 minutes!), then switch to the Izu Kyuko Line toward Shimoda. This is fast and cost-effective if the pass is already in your pocket.
Getting to Shuzenji (Western Izu)
For western Izu and Shuzenji, take the Tokaido Shinkansen or express train to Mishima, then transfer to the Izu Hakone Railway Sunzu Line to Shuzenji (about 35 minutes, ~¥540). Total from Tokyo: approximately 1 hour 20 minutes.
Day 1 Itinerary: Coastal Views, Hot Springs & Fresh Seafood
This itinerary follows a logical south-to-north flow — take the first morning train to Shimoda, then work your way back north by the end of Day 2, making your return to Tokyo smooth and stress-free.
7:00 AM — Depart Tokyo Station
Catch the first Odoriko or Shinkansen + Izu Kyuko combination. Grab an ekiben (train station bento) at Tokyo Station’s Gransta food hall for breakfast on board.
9:30 AM — Arrive Shimoda & Explore Perry Road
Start in Shimoda, the historic port where American Commodore Perry signed Japan’s opening treaty in 1854. Stroll Perry Road — a willow-lined canal walk lined with old stone buildings now housing cafes and craft shops. Don’t miss the Ryosenji Temple (¥500 entry), where the Convention of Kanagawa was signed.
11:00 AM — Shirahama Beach
Shirahama Beach, just 10 minutes by bus from Shimoda Station, is one of Izu’s most stunning — 800 meters of white sand backed by a forested headland. In spring and autumn, you may have it nearly to yourself. In summer, it’s a full beach party (still gorgeous). Entrance to the beach area is free.
12:30 PM — Seafood Lunch in Shimoda
Head back into Shimoda for lunch. The specialty here is kinmedai (splendid alfonsino) — a deep-sea red snapper unique to Izu waters. Try Gorosaya near the harbor for fresh sashimi sets (around ¥1,500–¥2,500). Alternatively, grab a seafood don (rice bowl) from one of the casual spots near the fish market.
2:00 PM — Rendaiji Onsen & Check-In
Take a short train ride north to Rendaiji Station (one stop from Shimoda), home to several excellent mid-range ryokans. Check into your accommodation, rest, and prepare for the evening onsen ritual. Many ryokans here have private rotenburo (outdoor baths) overlooking riverside gardens.
6:00 PM — Kaiseki Dinner & Evening Soak
Most ryokans include a multi-course kaiseki dinner featuring local seafood, mountain vegetables, and tofu. After dinner, soak in the communal or private onsen under the stars. This is the quintessential Izu evening experience.
Day 2 Itinerary: Hidden Coves, Historic Temples & the Drive Home
8:00 AM — Ryokan Breakfast & Morning Onsen
Start with the ryokan’s traditional Japanese breakfast (rice, miso soup, grilled fish, pickles) and a morning soak. Check out by 10 AM.
10:00 AM — Joren Falls & Nanadaru Waterfall Area
Head inland toward the Joren Falls (浄蓮の滝) — one of Japan’s most beautiful waterfalls, surrounded by ancient wasabi fields and dense forest. It’s 25 meters high and framed by native Japanese ferns. Entry to the viewing area: ¥600. A nearby shop sells fresh wasabi soft cream (around ¥400) — trust us, it’s addictive.
12:00 PM — Shuzenji Onsen Town & Lunch
Continue north to Shuzenji, Izu’s most atmospheric onsen town. Walk along the Katsura River past traditional inns to reach Shuzenji Temple, founded by the Buddhist monk Kobo Daishi in 807 AD. The town’s famous Tokko-no-yu footbath in the river is free and a lovely spot to rest weary feet. For lunch, try soba noodles or yuba (tofu skin) dishes at one of the riverside restaurants (¥1,000–¥1,800).
2:00 PM — Atami for Coastal Views & MOA Museum
Wrap up the trip in Atami, where the hillside MOA Museum of Art houses a world-class Japanese art collection with sweeping ocean views (entry: ¥1,600). Alternatively, stroll the Atami Sun Beach waterfront and browse the old-school shotengai (shopping arcade) for dried fish and wagashi (Japanese sweets) to bring home as omiyage (souvenirs).
4:30 PM — Return to Tokyo
Catch the Shinkansen or Odoriko from Atami back to Tokyo. You’ll be back at Tokyo Station by 5:30–6:00 PM — plenty of time to unwind at home with Izu memories fresh in your mind.
• If using public transport on Day 2, the Izu Kyuko Line + Tokai Bus combination can get you to Joren Falls (Kawazu direction), but buses are infrequent. Check timetables in advance at the Shimoda Tourism office or on the Tokai Bus website.
• Shuzenji to Atami by bus takes about 70 minutes (Tokai Bus Mishima line) — scenic and relaxing.
• Download the Japan Transit Planner app (Jorudan or Hyperdia) for real-time connections.
Where to Stay: Best Ryokans and Hotels for Every Budget
Accommodation in Izu ranges from ultra-luxury cliff-top ryokans to clean, affordable guesthouses. Here’s a practical breakdown to help you choose based on your travel style and budget.
| Budget Tier | Type | Price Per Night (Per Person, incl. 2 meals) | Best Area |
|---|---|---|---|
| 💴 Budget | Guesthouse / Business Hotel | ¥5,000–¥9,000 | Shimoda, Atami |
| 💰 Mid-Range | Traditional Ryokan | ¥15,000–¥25,000 | Rendaiji, Shuzenji, Ito |
| 💎 Luxury | Kaiseki Ryokan with Private Onsen | ¥35,000–¥80,000+ | Higashi Izu, Shuzenji |
Top recommendation for value: A mid-range ryokan in Rendaiji Onsen or Shuzenji gives you the full Japanese experience — tatami rooms, yukata robes, private or shared onsen, and a kaiseki dinner — without the four-figure price tag. For couples, look for rooms with “kashikiri” (reserved private baths), which many mid-range properties now offer.
Getting Around Izu: Car Rental vs. Public Transport
Public Transport: Feasible, but Requires Planning
The eastern Izu coast (Atami → Ito → Kawazu → Shimoda) is well-served by the Izu Kyuko Line, making it genuinely feasible without a car for first-time visitors. The challenge is the interior and western Izu — buses exist but run infrequently (sometimes just 3–4 times per day), and timetable misses can waste hours.
Car Rental: Freedom, but Know the Caveats
Renting a car from Shimoda, Atami, or Mishima unlocks the entire peninsula — including cliffside drives on the Nishi Izu Skyline, hidden beach coves like Dogashima, and the beautiful Daruma Mountain highlands. Budget around ¥7,000–¥10,000 per day for a compact car, plus ¥1,500–¥2,500 in highway tolls. Parking is generally free or very cheap at sightseeing spots.
Our verdict: If there are 2+ of you and you want maximum flexibility, rent a car. Solo travelers or those on a straightforward Shimoda-Shuzenji route can manage comfortably on trains and the occasional taxi or bus.
- ✅ Train-friendly itinerary: Tokyo → Shimoda (Day 1) → Shuzenji → Atami → Tokyo (Day 2)
- 🚗 Car itinerary bonus: Add Dogashima sea caves, Nishi Izu coast drive, and Daruma highlands
- ⚠️ Avoid driving in Shimoda city center on summer weekends — traffic is brutal
