Ito Onsen travel guide: why this Izu hot spring town is worth a stay
Why Ito Onsen is a good choice for hot spring travel
Steam rises above the Sagami Bay coastline as local trains roll into Ito Station and the air shifts from salty to faintly mineral. Ito Onsen, on the eastern side of the Izu Peninsula in Shizuoka Prefecture, is one of Japan’s classic hot spring towns, yet it feels quieter and more residential than the country’s most famous resorts such as Hakone or Kusatsu. That balance – real everyday life plus serious hot springs – is precisely what makes it a good choice for travelers seeking a refined, not overly staged, onsen experience on the Izu coast.
The town draws its hot spring water from a network of sources beneath Ito City, with temperatures that emerge hot enough to feed both public baths and traditional Japanese inns. According to the Ito City tourism office, more than 700 springs supply the area, and many properties pipe this spring water directly into their own baths, sometimes into open air tubs overlooking the sea, sometimes into deep indoor hinoki (cypress) tubs attached to a guest room. You come here less for spectacle and more for the rhythm of bathing, resting, and walking the compact streets that slope down toward the harbor and the Matsukawa River.
Compared with more crowded destinations, Ito Onsen offers a slower pace and a wider range of accommodations. There are long-established ryokan such as Tokaikan (a preserved former hot spring inn now open for day visits), modest hot spring hotels, and a handful of more contemporary stays, all within easy reach of coastal attractions and the volcanic landscapes of Izu. For travelers who value the quality of the water and the atmosphere of the town over nightlife or shopping, Ito is often a better fit than larger, more global resort areas in Shizuoka Prefecture.
The character of Ito’s hot springs and bathing culture
Mineral-rich, clear, and usually soft on the skin, the hot springs in Ito have a character that regular onsen travelers quickly learn to recognize. The water is typically piped from source to bath with minimal cooling, which means it can feel very hot at first immersion, especially in a deep spring bath. Many inns provide a small cold-water tap at the edge of the tub, allowing guests to adjust the temperature slightly while still preserving the feel of true Ito onsen water.
Some sources in the area are known as drinkable hot springs, offered in small cups near certain public facilities or hotel lobbies. The taste is faintly metallic, sometimes with a hint of salt, and locals will tell you it is good for digestion. Whether you choose to drink or simply bathe, the basic ritual is the same: rinse carefully before entering, soak quietly, and keep towels out of the water. This is not a spa in the Western sense but a deeply rooted Japanese bathing culture that emphasizes shared etiquette and unhurried soaking.
Open air baths – the coveted rotenburo – are where Ito Onsen really shines. On clear evenings, you may feel the sea breeze while sitting in a stone tub, the only sounds being running water and the distant bell of a train crossing near the river. Some inns alternate men’s and women’s areas morning and evening, so it is worth checking the schedule at check-in. Private family baths or in-room open air tubs are increasingly common in higher-end accommodations in Ito, appealing to couples, families, and travelers who prefer to bathe alone or with a partner while still enjoying natural hot spring water.
Where to stay in Ito Onsen and how to choose
Streets around the Matsukawa River, especially near the stone bridges on Chuo-dori, concentrate many of the classic hot spring inns in Ito City. Staying here places you within a short walk of the waterfront promenade, the historic Tokaikan building, and several small public baths, making it easy to weave quick soaks into your day. Properties closer to Ito Station are more practical for short stays or for travelers carrying larger luggage, with straightforward access to JR Ito Line trains toward Atami, Tokyo, and the rest of the Izu Peninsula.
Further south, toward the coast road leading to Kawana and beyond, you find larger hot spring hotels with more rooms and broader facilities. These often feature multiple spring baths – indoor, outdoor, and sometimes a dedicated air bath style space with strong ventilation and views – plus Japanese and Western-style rooms. The trade-off is clear: more choice of facilities and sometimes better sea views, but a little more distance from the nostalgic backstreets and older public baths in the town center, where you will find small sento-style facilities used by locals.
When comparing accommodations in Ito, focus on three elements before you check availability: the type of hot spring baths (shared, private, open air), the style of room (tatami with futon or Western beds), and the overall scale of the property. Smaller ryokan tend to offer a more intimate, traditional Japanese experience with fewer guests in the baths at once. Larger hotels may suit multi-generational families or groups who want variety – several pools, lounges, and perhaps easy access to nearby attractions such as Mount Omuro or Izu Kogen – over hushed, ryokan-style quiet.
Rooms, bathing facilities, and what to expect inside
Sliding open the door of a typical Ito hotel room, you will usually step onto tatami, not carpet. Many traditional inns in Ito Onsen still follow the classic pattern: a low table and zabuton cushions in the center of the room, shoji screens filtering the light, and futons laid out by staff while you are at dinner. Some newer accommodations in Ito offer hybrid rooms with beds on raised tatami platforms, a good compromise for travelers who want the atmosphere of a ryokan without sleeping directly on the floor.
Bathrooms vary widely. At the simpler end, you may find only a compact unit bath in the room and be encouraged to use the large communal hot spring baths downstairs. At the higher end, suites sometimes include a private open air bath on a balcony or terrace, fed by Ito onsen water. These in-room tubs are particularly appealing in cooler months, when you can slide open the window, feel the cold air on your face, and sink into the hot spring water in complete privacy after a day of walking around town.
Inside the communal bathing areas, expect separate zones for washing and soaking, with low stools, handheld showers, and a range of amenities. Some properties offer multiple pools at slightly different temperatures, or a spring bath with a view over the town’s tiled roofs and the Matsukawa River. The etiquette is consistent across Ito: bathe naked, wash thoroughly before entering, keep your voice low, and avoid bringing phones or cameras into the bath area. For many guests, these quiet, repeated rituals become the real highlight of a stay in Ito Onsen and a memorable part of an Izu Peninsula itinerary.
Location, access, and nearby attractions around Ito
Local trains from Atami trace the coastline to Ito Station, a journey that already feels like part of the trip. The JR Ito Line takes about 25 minutes from Atami, and limited express Odoriko services from Tokyo reach Ito in roughly 1 hour 40 minutes, according to timetables published by JR East. Once you arrive, most hot spring inns are within a 5 to 15 minute taxi ride, with some smaller properties located on the gentle hills above the town. The compact size of Ito City makes it easy to combine bathing with short walks; from the station to the harbor, for example, is roughly 1 km, passing small cafés, fish shops, and the occasional foot bath tucked beside the pavement.
Beyond the baths, Ito offers easy access to some of Izu’s most distinctive landscapes. Mount Omuro, a perfectly rounded extinct volcano about 8 km inland, is one of the area’s signature attractions. A short Omuroyama Ropeway ride takes you to the crater rim, where a circular walking path offers wide views over the peninsula and, on clear days, toward the ocean and sometimes Mount Fuji. Pairing a morning walk on Mount Omuro with an afternoon soak back in town is one of the most satisfying ways to structure a day here, especially in spring or autumn.
Coastal paths near Ito showcase rugged rock formations and small coves, while inland you will find gardens and seasonal flower parks such as Izu Shaboten Zoo near Mount Omuro. Travelers who enjoy a balance of gentle sightseeing and long, unhurried baths will find Ito Onsen particularly appealing. Those seeking intense nightlife or a dense cluster of global luxury brands may feel underwhelmed; this is a place for hot springs, sea air, and the quiet pleasure of returning to the same bath several times a day.
Who Ito Onsen suits best and how to compare it
Repeat onsen travelers often choose Ito when they want serious hot springs without the crowds of more famous resorts. The town suits couples who enjoy slow travel, solo guests who prioritize the quality of the water and the calm of the bath, and families looking for straightforward, comfortable hotels with reliable hot springs. The atmosphere is relaxed rather than ostentatious, even in more premium properties, which makes it a good fit if you value substance – the spring water, the view, the food – over showy design or nightlife.
Compared with inland mountain resorts, Ito’s coastal setting offers milder winters and the option to combine bathing with seaside walks. Versus larger Izu resort areas, Ito feels more compact and lived-in, with everyday shops and local restaurants alongside the inns. If you want a highly curated, ultra-secluded retreat, you might look elsewhere on the peninsula, such as the more remote parts of Higashi-Izu. If you prefer a town where you can step out after dinner, wander along the river, and still be back in your room within minutes, Ito is a strong candidate for a base on the eastern Izu Peninsula.
Before you book, think about your own bathing habits. If you plan to spend most of your time in the water, prioritize properties with multiple hot spring baths, including at least one open air option. If you are traveling with someone new to Japanese bathing culture, consider an inn that offers private or reservable baths in addition to the shared ones. In Ito Onsen, the right match between your travel style and the character of the inn will matter more than any single amenity, and reading recent reviews or official tourism information can help you choose confidently.
Is Ito Onsen a good destination for first-time onsen travelers?
Yes, Ito Onsen works very well for first-time onsen travelers because it combines authentic Japanese bathing culture with a gentle, easy-to-navigate town. The hot springs are central to daily life, but the atmosphere is relaxed, and many inns are used to welcoming guests who are new to onsen etiquette. Clear signage, manageable distances, and the presence of both traditional ryokan and more modern hotels make it a comfortable introduction to hot spring travel in Japan, especially for visitors arriving from Tokyo or Atami.
How many nights should I stay in Ito Onsen?
Two nights is usually the sweet spot for Ito Onsen, allowing you to settle into the rhythm of morning and evening baths while still exploring nearby attractions such as Mount Omuro, Izu Kogen, or the coastal paths. A single night can feel rushed, especially if you arrive late and leave early, while a third night suits travelers who want to slow down, repeat favorite baths, and perhaps try more than one style of accommodation in Ito, such as a traditional ryokan followed by a modern hot spring hotel.
Do I need a car to enjoy Ito Onsen and the Izu Peninsula?
You do not need a car to enjoy Ito Onsen itself, as the town is compact and many inns are a short taxi or even walking distance from Ito Station. For wider exploration of the Izu Peninsula, a car offers more flexibility, but key spots such as Mount Omuro, Izu Shaboten Zoo, and several coastal viewpoints are accessible by local bus or taxi from Ito Station and Izu Kogen Station. Travelers focused mainly on hot springs and the immediate surroundings can comfortably rely on public transport and short taxi rides.
What should I look for when choosing a hot spring inn in Ito?
When choosing a hot spring inn in Ito, focus first on the baths: check whether the property uses natural hot spring water, offers open air tubs, and provides any private or reservable baths. Next, consider room style – traditional tatami with futons or Western beds – and the overall size and atmosphere of the hotel. Finally, look at location within Ito City, deciding whether you prefer to be near the station for easy train access, close to the river and harbor for evening walks, or slightly elevated for wider views over Sagami Bay and the town.
Is Ito Onsen suitable for travelers with tattoos?
Policies on tattoos vary by property in Ito Onsen, as they do across Japan. Some inns allow tattoos without restriction, others may ask guests with visible tattoos to use private baths, and a few still restrict access to shared facilities. If this is a concern, it is wise to verify the tattoo policy of your chosen accommodation in Ito before finalizing your plans, or to prioritize stays that offer private or in-room hot spring baths so you can enjoy the onsen experience comfortably.
