Atami is one of the most popular hot spring towns near Tokyo — close enough for an easy day trip, with a lively seaside atmosphere that draws crowds year-round. But a short drive south of the busy station area, in a quieter stretch called South Atami, sits a smaller, lesser-known inn with a genuinely excellent private bath: New Tomiyoshi.
Why New Tomiyoshi stands out:
- Private ocean-view outdoor baths you can enter as many times as you like during your visit
- A genuinely excellent seafood lunch — sashimi, seafood rice, and more — included in the day-trip plan
- A calm, uncrowded setting just south of Atami’s busy main district
- A rare hypertonic spring, among the more mineral-concentrated waters in Japan

Getting There from Tokyo — Access Guide
Atami is one of the easiest hot spring destinations to reach from Tokyo, and New Tomiyoshi sits a short ride further south along the coast.
🚄 By Train (Recommended)
Take the Tokaido Shinkansen from Tokyo Station to Atami Station (approx. 35–50 minutes). From Atami, either transfer to the JR Ito Line and ride two stops to Izu-Taga Station, followed by a 10-minute walk to the inn (no taxis available at this small station — walking is the only option); or take a local bus from Atami Station Bus Terminal (platform 6, bound for “Ajiro Asahi-chō”) and get off at the “Kaisuiyokujō” (beach) stop, a short walk from the inn. The bus ride takes about 20 minutes.
🚗 By Car
From central Atami, head south along the coastal road — about 10 minutes’ drive to South Atami.
| Route | Tokyo Station → Atami Station → Izu-Taga Station or bus → New Tomiyoshi |
|---|---|
| Shinkansen | Tokaido Shinkansen, Tokyo → Atami (~35–50 min) |
| From Atami Station | JR Ito Line to Izu-Taga (~10 min) + 10-min walk, OR local bus (~20 min) to “Kaisuiyokujō” stop |
| JR Pass | ✅ Shinkansen and Ito Line both covered by standard JR passes |
A Quiet Escape from Atami’s Crowds
Central Atami, near the train station, is where most visitors head — and it can get busy, especially on weekends. New Tomiyoshi sits a little further south, near Nagahama Beach, in a noticeably quieter part of town. If you’d rather skip the crowds without sacrificing an excellent ocean-view bath, this is exactly the kind of place worth knowing about.
One practical note for the day-trip lunch plan: guests use a rest lounge rather than a private guest room, so it’s not designed for a long, leisurely stay in a private space. The trade-off is that the private baths are available on a first-come basis throughout your visit — so you’re free to bathe more than once if you’d like.
The Hot Spring — A Rare Hypertonic Water
♨ What Does “Hypertonic” Mean?
Japanese hot springs are classified by mineral concentration into low-tonicity (under 8 g/kg), isotonic (8–10 g/kg), and hypertonic (10 g/kg or more) categories. New Tomiyoshi’s water, at 17.37 g/kg, ranks among the more concentrated hypertonic springs found anywhere in the country. Minerals absorb into the skin more readily in water this strong, which also means it’s easier to lose fluids and overheat —stay hydrated and avoid overly long soaks
Private Ocean-View Outdoor Baths — The Main Attraction ★
The heart of a visit here is the rooftop private bath area on the main building, with four individually designed outdoor baths (three were available during this visit). Each is available on a first-come, first-served basis — simply check if one is free and let yourself in.
Ten (天) — A beautifully crafted Shigaraki-ware ceramic tub with an open, unobstructed view of the sea below. Because the baths sit on the rooftop, the ocean view is especially dramatic.
The water in this rooftop bath is nearly colorless, with a light salty taste from its proximity to the sea — and because of the salt content, the warmth lingers pleasantly on the skin long after you’ve stepped out. Temperature runs a comfortable 41–42°C.
Kuu (空) — A square tub built from Kiso hinoki (Japanese cypress), with a gentle, warm wood fragrance and the same striking sea view. A privacy fence around the perimeter means you can relax without concern for onlookers.
Annex Baths — Indoor & Garden-Style Outdoor
Left: The annex indoor bath — a larger, simpler tub with room to stretch out. Right: A garden-style outdoor bath with rock features and its own ocean view, always available with no reservation needed.
Beyond the private rooftop baths, a separate annex building offers a straightforward indoor bath and a garden-style outdoor bath using the same spring. Unlike the private baths, these are open-access at any time — a good option if all the private baths happen to be occupied, or simply for a change of scenery.
The Lunch Plan — Fresh Izu Peninsula Seafood
🍚 What is Kamameshi?
Kamameshi is rice cooked and served in a small individual iron pot, typically layered with seafood, vegetables, or meat that infuses the rice as it cooks. It’s a popular regional specialty along Japan’s coastlines, and the seafood version here — with scallop, shrimp, and fish — is a genuine highlight of the meal.
Left: A sashimi platter showcasing the quality of Izu Peninsula seafood. Right: Satsuma-age (fried fish cake), ordered as an extra — crisp on the outside, tender within, with the umami of fresh fish coming through clearly.
The meal alone would justify the trip, and it left a strong impression that a full overnight stay — with a proper dinner course — would be well worth returning for.

Final Thoughts
New Tomiyoshi is easy to overlook if you’re only looking at Atami’s main strip, but that’s precisely its appeal: a quiet setting, private baths with a real ocean view you can enjoy more than once, and a lunch that punches well above what you’d expect from a day-trip plan. For travelers who want the convenience of Atami without the crowds, this is a genuinely worthwhile detour.
New Tomiyoshi is ideal for visitors who:
- Want a private, ocean-view bath without the busiest crowds of central Atami
- Are looking for a day trip that pairs bathing with a genuinely good seafood meal
- Prefer a quieter, more local corner of the Atami/Izu coastline
- Want the flexibility to enter their private bath more than once during a visit
