Ito is a coastal hot spring town on the eastern shore of the Izu Peninsula, about two hours by train from Tokyo. With over 700 natural spring sources, ryokan inns overlooking the Pacific, and dramatic volcanic scenery just south of town, it has drawn visitors seeking rest and nature for centuries. The rugged Jogasaki Coast, the grass-covered crater of Mount Omuro, and capybaras soaking contentedly in outdoor baths give Ito a character that blends traditional onsen culture with coastal wildness and genuine quirk.
The best time to visit Ito is from early April through late June, when spring cherry blossoms give way to mild early summer warmth, the Jogasaki Coast hiking trails are at their finest, and accommodation deals are easy to find outside of Golden Week. Plan around the week of late April to early May if you want to avoid the Golden Week holiday surge, when domestic travel spikes. A strong secondary window runs from mid-September through mid-November, when autumn foliage transforms the slopes around Mount Omuro and the crowds thin after the summer beach season. Both windows deliver comfortable temperatures and relatively dry conditions, making them ideal for the mix of hot spring relaxation and outdoor exploration that defines Ito.
Spring in Ito, Japan
Spring is when Ito rewards you most. Sakura no Sato, the cherry blossom park at the foot of Mount Omuro, is home to around 1,500 trees of roughly 40 varieties, and the peak Somei Yoshino bloom typically falls in late March through early April with nighttime illuminations turning the park into a spectacle after dark. Afternoons warm to highs of 66°F (18.9°C), ideal for the chairlift ride up Mount Omuro, where clear spring skies offer the best chance of spotting Mount Fuji from the crater rim. Mornings still carry a chill at 50.7°F (10.4°C), so dress in layers for early walks along the Matsukawa River in downtown Ito.
Rain is relatively scarce through the season, with scattered showers only occasionally interrupting outdoor plans. The historic Tokaikan, a grand wooden ryokan from 1928 that now operates as a museum and public bathhouse along the Matsukawa River, makes a perfect rainy-day backup. Tourism is fairly slow during spring, and accommodation is easier on the budget, though a significant exception comes during Golden Week in late April to early May, when Constitution Memorial Day, Greenery Day, and Children's Day create a string of national holidays that send domestic visitor numbers soaring. Book early if you're visiting that week, or plan around it for quieter trails and lower room rates.
By May, the Jogasaki Coast hiking trail is lush and green, and the 10-kilometer path past the Kadowakizaki Suspension Bridge and lighthouse feels refreshingly uncrowded compared to summer. A light waterproof jacket is smart to carry as rain chances begin ticking upward toward the end of the season.
Summer in Ito, Japan
Summer in Ito revolves around the sea and the town's biggest annual celebration. The Anjin Festival, held over three days around August 10, commemorates William Adams, the English navigator who built Japan's first Western-style sailing ship here in 1600. The festival includes taiko drum competitions, yosakoi dance performances in the streets, lanterns floated down the Matsukawa River, and a finale of roughly 10,000 fireworks launched from five points over Sagami Bay. Earlier in July, the quirky Matsukawa River Tub Riding Race draws locals who paddle barrels downstream in one of the peninsula's most entertaining spectacles.
The heat is real, though. Seasonal highs average 83.5°F (28.6°C) with lows of 71°F (21.6°C), and humidity climbs past 70%, giving the air a sticky weight that lingers well after sundown. Mid-August pushes peak heat to highs of 89.9°F (32.2°C) with overnight lows of 76.3°F (24.6°C), making air-conditioned ryokan and ocean dips essential relief. Ito Orange Beach, a short walk from the station, and Kawana Beach to the south both fill with families taking advantage of the warm water. The rainy season, known as tsuyu, typically affects June, so expect higher precipitation chances before July settles into drier, steamier weather.
This is Ito's busiest season, and accommodation prices climb accordingly. Long summer evenings, with sunset after 6:30pm, extend your time outdoors, but plan strenuous hikes along the Jogasaki Coast for early morning before the midday heat sets in. Bring breathable clothing, sunscreen, and a refillable water bottle.
Fall in Ito, Japan
By mid-September, the summer crowds ease and Ito enters a genuinely pleasant stretch. The leaves around Izu Kogen begin changing color later than colder parts of Japan, and by November the hillsides around Mount Omuro glow in shades of orange and gold against clear blue skies. Sakura no Sato, famous for its spring blossoms, actually starts a second round of cherry bloom with autumn-flowering varieties beginning in late September, an unusual sight that most visitors don't expect.
Highs of 71.8°F (22.1°C) paired with lows of 60.5°F (15.8°C) make this the most comfortable season for coastal hiking and outdoor onsen bathing. Showers pick up a bit, with precipitation occurring every few days, so pack a compact rain jacket. The Izu Shaboten Zoo, where capybaras famously soak in hot spring baths, is especially enjoyable in this cooler weather. Respect for the Aged Day and the Autumnal Equinox in September create long weekends that draw domestic visitors, but overall the pace is more relaxed than summer.
October remains one of Ito's most popular months, so booking a few weeks ahead is wise for ryokan stays. November quiets down further, and the shortened daylight, with sunset before 5pm, means early starts for the Jogasaki Coast trail. Bring a medium-weight jacket for evening onsen strolls along the Matsukawa riverfront.
Winter in Ito, Japan
Winter strips Ito down to its essentials: hot springs, fresh seafood, and solitude. The town sees its lowest visitor numbers between December and February, which means ryokan that might feel crowded in summer now offer a more intimate experience. Soaking in an ocean-view outdoor bath while cool air sits on your shoulders is the signature winter pleasure here. The Tokaikan museum and public bath makes for a leisurely afternoon, and the Izu Shaboten Zoo's famous capybara onsen sessions are a wintertime staple.
Highs reach 52.7°F (11.5°C) and lows drop to 39.7°F (4.3°C), crisp but never harsh; snow is essentially nonexistent along this coastal stretch. Rain appears now and again, but January is one of the driest months. Winter daylight is limited, with fewer than 10 hours of sunshine in December, so plan outdoor activities for midday. Mount Omuro's chairlift still runs, and on clear winter mornings the views of Mount Fuji from the crater rim can be the sharpest of the year.
New Year's is an important holiday period in Japan, and some ryokan offer special multi-course New Year's meals featuring local seafood. Expect higher prices and limited availability around the first week of January. For the rest of winter, you'll find the best accommodation value of the year and near-empty hiking trails. Bring warm layers for morning walks and a hat for the exposed chairlift ride up Mount Omuro.

Travel Tips & Safety for Ito, Japan
Getting to Ito from Tokyo is straightforward. The JR Odoriko limited express runs directly from Tokyo Station to Ito Station in about 100 minutes, and the trip is covered by the Japan Rail Pass and Tokyo Wide Pass. A cheaper alternative is the Tokaido Line to Atami, then a local train transfer to Ito, which adds time but saves money. Once in town, the Tokai Bus network reaches Mount Omuro, the Jogasaki Coast, and Izu Shaboten Zoo; a one-day or two-day bus pass from Ito Station covers most sightseeing stops and is more economical than paying per ride.
Ito is very safe for visitors. Standard precautions apply: keep valuables secure in crowded festival settings, and watch your footing on the volcanic rock along the Jogasaki Coast trail, especially after rain when surfaces get slippery. Typhoon season runs roughly from August through October, so check forecasts if you're visiting during that window and be prepared for occasional trail closures.
