Atami Onsen

What to expect

Atami is a hillside resort city on the east coast of the Izu Peninsula, looking out over Sagami Bay. It has been one of the Tokyo region’s go-to hot spring towns for well over a century, and it shows it: big hotels climb the slopes behind the beach, the station shopping streets sell dried fish and onsen buns, and steam leaks from vents on the old lanes above the port.

Do not come expecting a cluster of rustic public bathhouses. Most of Atami’s hot water flows into hotel and ryokan baths, and the main day options are two large modern spas by the harbour. The town’s tourism association splits day bathing into hotels and inns that accept day guests when they have space, plus a handful of dedicated day facilities. That makes Atami a good choice when you want an easy, comfortable soak with a sea view and dinner after, and less of one if your idea of an onsen is a creaky wooden bathhouse.

Where to soak

• Ocean Spa Fuua (10-1 Wadahama-minami-cho), part of the Atami Bay Resort Korakuen complex, is the largest day spa in town. Its highlight is a standing outdoor bath about 25 m long that seems to run straight into the bay. It also has a view sauna with löyly, two kinds of stone-bed bath and lounges. No swimsuits: the baths are separated by sex and you bathe naked. Open 10:00 to 22:00, last entry 21:00. Closed on irregular days; listed closures include January 5 and 6, 2027. Children under 4 are not admitted, children from 4 through elementary school must come with a parent of the same sex, under-18s need a guardian aged 20 or over, and the standing bath needs a height of at least 135 cm.
• Marine Spa Atami (4-39 Wadahama-minami-cho) is an all-weather hot spring and pool complex where everyone wears swimsuits. It has a 25 m pool, a lazy river, a water slide with about an 8 m drop and a health bath area with 11 bathing styles. Open 10:00 to 19:00, last entry 18:30, and closed on Thursdays, with seasonal changes. Entry can be restricted in summer.
• Atami Ekimae public bath (Tawara Yokujo), near the station, is a small local bathhouse closed on Wednesdays (0557-81-3417).
• Yamada-yu, in the western part of town, is a neighbourhood bathhouse with its own phone line (0557-81-9635). Call for current hours.
• Hotels with day bathing listed by the tourism association include Tsuki no Sumika Atami Juraku Hotel, Yuyado Ichibanchi, Ooedo Onsen Monogatari Atami, KKR Hotel Atami, Atami Seaside Spa and Resort, Yuyado Mikan no Ki, Hotel Yume Iroha, Shukaen, Hotel New Akao, Shinkadoya and, in Ajiro to the south, Hiraturu. Hotels can refuse day guests when busy, so phone ahead.

Right outside the station, Ieyasu no Yu is a free footbath, open 9:00 to 16:00, named after the shogun Tokugawa Ieyasu.

Getting there

Atami Station is served by the Tokaido Shinkansen (Kodama and some Hikari trains) and the JR Tokaido Line, which makes Atami one of the easiest hot spring towns to reach from Tokyo; the shinkansen takes under an hour. Some JR limited express trains to the Izu Peninsula also stop here.

From the station, buses for Atami Port and Ajiro reach Marine Spa Atami in about 10 minutes. Ocean Spa Fuua runs a free shuttle from the station (about 10 minutes), or take the Atami Port and Korakuen bus to the last stop. The Yu-Yu sightseeing loop bus was suspended on all days in October 2026. Fuua has 230 parking spaces (¥500 for 5 hours); Marine Spa uses the municipal Wadahama lot next door, with 125 spaces and a parking discount for bath users.

When to go

Atami is busy all year and very busy on Japanese holiday weekends, in summer beach season and around New Year. Weekdays are noticeably calmer. Winter is mild by the sea and good for outdoor baths. The evening tickets at Fuua (from 17:00 and 20:00) are cheaper and miss the day-trip crowds.

Prices and booking

• Ocean Spa Fuua: adults ¥3,080, children ¥2,310. After 17:00, ¥2,310 and ¥1,760. After 20:00 (bathing only), ¥1,110 and ¥770. Weekends, holidays and special dates add ¥330 (adults) and ¥220 (children). Adults also pay ¥150 bathing tax. Entry includes loungewear and towel rental. No advance booking.
• Marine Spa Atami: adults ¥1,360, elementary and junior high students ¥680, ages 3 to preschool ¥420, under 3 ¥310.
• Ieyasu no Yu footbath: free.

Prices are from the tourism association and Fuua’s own pages, checked in October 2026.

Onsen etiquette

At every bath except Marine Spa, bathing is naked and separated by sex. Wash fully at the shower stations before you get in, keep your small towel out of the water, tie up long hair and do not swim. Swimsuits are not allowed at Fuua. At Marine Spa it is the reverse: you must wear a swimsuit throughout. Keep phones out of the changing rooms and baths.

The Atami Nanayu walk

The old town has seven historic spring sources, the Atami Nanayu, marked with signboards. They are not for bathing, but they make a pleasant hour’s walk. The Oyu Geyser was once a powerful natural geyser that stopped erupting in 1923; since 1962 it has been preserved as a city cultural property and now erupts artificially about every five minutes. At Kosawa no Yu you can steam eggs in the vent; it was renovated in July 2023 with two steaming pots and new benches. In the Izusan district north of the station, Hashiri-yu is an old spring source in a cave by the shore, open 9:00 to 17:00 for viewing only.

Where to stay nearby

Atami has a very wide range of hotels and ryokan, from large resort hotels along the bay to small inns in the backstreets. Many include in-room or private baths, which helps if you have tattoos. Quieter alternatives along the same coast are Izusan just north of the station and Ajiro to the south.

Safety notes

• Hills: central Atami is steep. Lanes between the station, the old town and the port involve long slopes and stairs.
• Heat: drink water and take breaks between baths, especially in a sauna and outdoor bath circuit.
• Footing: wet stone floors at outdoor baths are slippery.
• Kids and height limits: check Fuua’s age and height rules before you go if you are travelling with children.

Nearby stops worth adding

Kiunkaku, an early 20th-century villa, and the MOA Museum of Art on the hill above the station are the two big cultural sights. Ferries run from Atami Port to Hatsushima island. The beach promenade and Atami Sun Beach are a short walk from both spas.
