Introduction
The first time I saw a fishing boat return to Numazu Port at 6 a.m., gulls screaming overhead and Mount Fuji sitting quiet and white across the bay, I understood why so many travelers search for the highlights of Nummazaki without quite knowing what they’re looking for. It isn’t a single town on a map. It’s the name travelers have started using online for the stretch of coastline south of Numazu City, where Suruga Bay meets the northern edge of the Izu Peninsula in Shizuoka Prefecture. However you found this name, the place behind it is real, reachable, and worth your time.
Quick Answer: The highlights of Nummazaki refer to the Suruga Bay coastline near Numazu City, Shizuoka Prefecture — a region known for dramatic sea cliffs, the world’s only deep-sea aquarium with coelacanth specimens, the remote fishing village of Heda, and clear views of Mount Fuji across Japan’s deepest bay. It’s a 60–90 minute train ride from Tokyo.
What Does “Nummazaki” Actually Mean?
Here’s something worth knowing before you plan a trip: Nummazaki isn’t an official Japanese place name you’ll find on a map or train timetable. It’s become shorthand, used mostly in English-language travel content, for the coastal zone stretching south from Numazu City along Suruga Bay toward the Izu Peninsula. Think of it less as a town and more as a region — similar to how travelers say “the Amalfi Coast” without meaning one specific address.
That distinction matters because a handful of other travel guides describe Nummazaki with inconsistent, sometimes invented details. This guide sticks to what’s actually there: Numazu City, the fishing village of Heda, Shuzenji Onsen, and the wild western shoreline of the Izu Peninsula. In addition, everything below reflects real transit times, real attractions, and real prices, so you can plan with confidence instead of guesswork.
Overview of the Destination
Numazu sits on Suruga Bay, Japan’s deepest bay at roughly 2,500 meters, in Shizuoka Prefecture. That extreme depth is the reason the region feels so different from anywhere else in Japan. Cold, nutrient-rich water rises close to shore, feeding a fishing culture that still runs the local economy and putting some of the country’s freshest seafood on plates within hours of the catch.
Unlike Kamakura or the Izu east coast, this stretch hasn’t been fully absorbed into the standard Tokyo day-trip circuit. Meanwhile, the geography does a lot of the work for you: pine-fringed shoreline, volcanic cliffs, a working fishing port, and — on clear mornings — Mount Fuji rising directly across the water. Therefore, it rewards travelers who want texture and quiet over checklist sightseeing.
Best Time to Visit
| Season | Conditions | Best For |
| Winter (Dec–Feb) | Clearest skies, sharpest Fuji views, coolest coastal winds | Photography, fewer crowds |
| Spring (Mar–May) | Mild weather, cherry blossoms inland near Shuzenji | Hiking, comfortable walking |
| Summer (Jun–Aug) | Warm water, swimming season, higher humidity | Snorkeling, beach coves |
| Autumn (Sep–Nov) | Cooling temperatures, good visibility, typhoon risk in Sept | Hiking, seafood season |
If Mount Fuji views are your priority, aim for winter mornings, when cold, dry air keeps the horizon sharp. If you’d rather swim or explore tide pools, July and August offer the warmest water, though you should check typhoon forecasts before booking.
How to Reach the Nummazaki Coast
Getting here is more straightforward than the “hidden gem” label suggests.
From Tokyo:
- Tokaido Shinkansen (Kodama or Hikari) from Tokyo Station to Mishima Station: about 50–60 minutes
- From Mishima, transfer to the JR Tokaido Line for Numazu Station (one stop, under 10 minutes), or continue on the Izu-Hakone Railway toward Shuzenji (about 35–40 minutes)
- Total journey time: roughly 60–90 minutes to Numazu; around 2 hours to Shuzenji
From Shizuoka City: Around 30–40 minutes by local train.
Getting around once there: Public buses connect the main areas, but a rental car gives you access to Heda and the more remote western coastline, where bus service is limited to a handful of departures per day. Cash is still the safer default in smaller villages, since card acceptance is inconsistent outside the main towns.
Top Highlights of Nummazaki
1. Suruga Bay Cliffs and Coastal Trails
The coastline’s defining feature is its cliffs, carved by wind and wave action into a jagged, photogenic edge above the Pacific. Walking trails run along the top, ranging from easy 30-minute stretches to longer routes for committed hikers. On clear days, the elevated viewpoints line up Suruga Bay in the foreground and Mount Fuji on the horizon — a combination you won’t find in many other parts of Japan.
2. Numazu Deep Sea Aquarium & Coelacanth Museum
This is genuinely one of the most unusual highlights of Nummazaki, and it’s real, verifiable, and well worth the entry fee. It’s the world’s first aquarium built specifically around deep-sea species living below 200 meters, taking advantage of Suruga Bay’s extreme depth. The star attraction is its coelacanth collection — two frozen and three taxidermied specimens of the “living fossil” fish once thought extinct for millions of years. It’s located near Numazu Port, about 15 minutes by bus from Numazu Station, and admission runs around ¥1,600–¥2,200.
3. Heda: A Working Fishing Village
Heda, on the western shore of the Izu Peninsula, is about as far from a polished tourist stop as Japan gets. It’s Japan’s center for spider crab fishing — the largest crab species on earth — and the village has a genuinely unusual history: shipwrecked Russian sailors built a schooner here with local carpenters in 1854. Reaching Heda takes some effort (bus from Shuzenji Station, roughly 50 minutes on winding roads), which is exactly why it stays quiet.
4. Shuzenji Onsen
Often called the “Little Kyoto of Izu,” Shuzenji is a 1,200-year-old hot spring town built around a bamboo-lined stretch of the Katsura River. After a day on the cliffs, this is where you soak. Several ryokan offer private baths with mountain views, and the town’s Shigetsuden hall is the oldest wooden building on the Izu Peninsula.
5. Mount Fuji Views Across the Bay
Few places let you pair an ocean cliff, a working harbor, and Mount Fuji in a single frame. Winter mornings offer the clearest sightlines, when the mountain appears snow-capped against a sharp blue sky.
6. Pop-Culture Pilgrimage: Love Live! Sunshine!!
Numazu is the real-world setting for the anime series Love Live! Sunshine!!, and fans regularly travel here specifically to visit locations that appear in the show, alongside themed cafés and murals around the city.

Local Culture and Food
Food here follows one rule: freshness over presentation. Menus change daily based on the catch, and the standard order is simplicity — sashimi, grilled fish, and kaisendon (seafood rice bowls) piled with whatever came off the boats that morning.
- Sakuraebi (cherry blossom shrimp) — caught almost exclusively in Suruga Bay
- Kinmedai (splendid alfonsino) — a prized local catch, often grilled or simmered
- Spider crab — Heda’s specialty, in season through winter and spring
- Himono (dried fish) — a harbor-side street food staple
- Wasabi, grown fresh in the streams around Shuzenji, and worth trying in its raw form rather than the tube version most travelers know
Local culture centers on the sea in a way that’s hard to fake. Boats leave before sunrise, small harbor shrines mark the community’s ties to fishing, and festivals throughout the year follow the fishing calendar rather than a tourist schedule.
Budget Tips
| Expense | Approximate Cost |
| Shinkansen Tokyo–Mishima (one-way) | ¥4,500–4,700 |
| Izu-Hakone Railway Mishima–Shuzenji | ¥550 |
| Numazu Deep Sea Aquarium entry | ¥1,600–2,200 |
| Guesthouse/minshuku per night | ¥6,000–10,000 |
| Ryokan with meals per night | ¥15,000–30,000+ |
| Seafood meal at a harbor restaurant | ¥1,200–2,500 |
| Local bus fare | ¥200–1,000 depending on distance |
Pro tip: A 14-day Japan Rail Pass covers the Shinkansen to Mishima and the JR Tokaido Line, but it does not cover the Izu-Hakone Railway to Shuzenji — budget a small cash supplement for that leg.
1–3 Day Itinerary
Day 1 — Numazu & the Coast
Arrive via Mishima, drop bags in Numazu, then head straight to the harbor for the morning fish market energy (best before 8 a.m. if you can manage it). Spend the afternoon at the Deep Sea Aquarium, then walk the coastal cliff trails before sunset.
Day 2 — Shuzenji Onsen
Transfer to Shuzenji. Walk the bamboo grove along the Katsura River, visit Shigetsuden, and spend the evening soaking in a ryokan onsen with a kaiseki dinner.
Day 3 — Heda (for those with more time)
Take the bus from Shuzenji to Heda for the full fishing-village experience: spider crab lunch, views of the Mihama Peninsula, and a slower, more remote pace than anywhere else on this coast.
Hidden Gems and Local Secrets
- Early harbor mornings. The most memorable hour in the whole region is 6–7 a.m. at Numazu Port, before the tour groups are awake.
- Cape viewpoints outside the main trail. Ask at your accommodation for lesser-known lookout points — locals often know spots that don’t appear in English-language guides.
- Wasabi tasting in Shuzenji. Most travelers skip this entirely, but freshly grated wasabi tastes nothing like the paste most people know.
- Heda’s crab season. Winter and early spring bring the best spider crab prices, before peak-season demand pushes them up.
Travel Mistakes to Avoid
- Treating it as a single town. Since this is a coastal region, not one address, plan for movement between Numazu, Shuzenji, and Heda rather than expecting everything within walking distance.
- Skipping the JR Pass gap. The Izu-Hakone Railway to Shuzenji isn’t covered by the JR Pass — carry cash for that ticket.
- Visiting Heda without checking bus schedules. Service is infrequent; missing the last bus back can strand you.
- Assuming card payment everywhere. Smaller harbor restaurants and guesthouses often take cash only.
- Rushing through in a few hours. This region rewards slowness; a single afternoon barely scratches the surface.
Frequently Asked Questions
Is Nummazaki a real place in Japan?
Not as an official place name. “Nummazaki” is a term that’s emerged in online travel content to describe the Suruga Bay coastline near Numazu City in Shizuoka Prefecture, including areas like Heda and Shuzenji on the Izu Peninsula.
How do I get to the Nummazaki coast from Tokyo?
Take the Tokaido Shinkansen from Tokyo Station to Mishima Station (50–60 minutes), then transfer to a local train or the Izu-Hakone Railway. Total travel time to Numazu is around 60–90 minutes.
What is Nummazaki known for?
The area is known for its Suruga Bay coastal cliffs, the Numazu Deep Sea Aquarium and its coelacanth specimens, fresh seafood, the fishing village of Heda, and views of Mount Fuji across the bay.
Is one day enough to see the highlights of Nummazaki?
A single day covers Numazu’s port and aquarium comfortably. However, two to three days let you add Shuzenji Onsen and the more remote village of Heda for a fuller experience.
Is this area good for families?
Yes. The aquarium, harbor walks, and gentler coastal trails suit most ages, though the exposed clifftop sections require closer supervision with young children.
What’s the best time to see Mount Fuji from this coast?
Winter mornings offer the clearest, sharpest views, since cold, dry air keeps visibility high across the bay.
Do I need a rental car?
Not strictly. Public transport covers Numazu and Shuzenji well, but a car makes reaching Heda and the western Izu coastline far more flexible, since bus service there is limited.
Final Thoughts
The real highlights of Nummazaki were never about a single landmark. They’re in the hour before the fish market opens, the wasabi field steam rising off Shuzenji’s river, and the moment Mount Fuji clears the horizon across a bay most travelers never look at twice. If you’re planning a Japan itinerary beyond Tokyo and Kyoto, this stretch of Shizuoka coast deserves a spot on it.
