Hakone, tucked away in Kanagawa Prefecture, blends hot springs, mountain views, and ever-changing scenery. The vibe here shifts a lot depending on when you visit. Weather really shapes the whole trip, from those misty summer showers to winter’s crisp, clear skies that sometimes let you spot Mount Fuji. If you want comfortable weather, late March to May and late September to November are your best bets.
During these months, you’ll get mild temps, less rain, and some of Japan’s most stunning landscapes. Spring bursts with cherry blossoms and new greenery. Autumn brings fiery foliage and golden grasslands. Outdoor activities, sightseeing, and soaking in hot springs all feel extra special then.
If you know how Hakone’s weather shifts through the year, you can plan smarter. Understanding the seasons helps you pick the right time for lakes, ropeways, or historic trails, without getting caught by surprise rain, muggy heat, or winter’s chill.
Overview of Hakone’s Climate
Hakone sits in the mountains of Kanagawa, so it stays cooler than Tokyo. You’ll notice real differences between seasons, with cold winters, humid summers, and milder months in between.
Climate Classification and Seasonal Patterns
Hakone has a humid subtropical climate and you can really feel the seasonal changes. Winters get chilly but not brutal, while summers are warm and sticky. Spring and autumn are shorter but give you the nicest weather.
In winter, temperatures dip low enough for snow now and then, especially up in the mountains. The air feels crisp and the skies often stay clear. People flock to the hot springs during this time.
June through August brings warm, muggy days. The rainy season kicks off in June, and typhoons sometimes roll in late summer. You’ll see lots of cloudy days and heavy rain during these months.
Spring (late March to May) and autumn (late September to November) feel the most balanced. You get mild temperatures and fewer wild weather swings, so it’s perfect for being outdoors.
Temperature Ranges Throughout the Year
The average annual temperature in Hakone sits lower than Tokyo’s because of the higher elevation. Winter highs usually reach 7–10 °C, and nights can drop to 2 °C or even lower. You might see some snow, mostly in January and February.
Spring starts chilly but warms up, with highs climbing from 12 °C in March to about 19 °C by May. Nights stay cool, so you’ll want to bring layers.
July and August are the hottest, with daytime temps around 28 °C and nights at 21–22 °C. The heat isn’t brutal, but the humidity makes it feel warmer than it is.
Autumn cools fast. Highs are about 25 °C in September, but by November, you’re looking at 15 °C. Nights get pretty chilly, especially late in the season when they can dip below 10 °C.
Rainfall, Humidity, and Sunshine Trends
Rain really defines Hakone’s weather. The wettest stretch runs from March through October, and spring and early summer often see over 250 mm of rain each month. June gets hit the hardest, averaging more than 350 mm thanks to the rainy season.
Humidity climbs in summer, often topping 70–80%. That makes hiking feel tougher. Typhoons in late summer can dump a lot of rain fast.
December and January are the driest, with just about 60 mm of rain each. You’ll get clearer skies then, with more sunshine and better chances to spot Mount Fuji.
Autumn feels more balanced, with moderate rain and humidity. October and November are great for sightseeing and catching the fall colors.
Best Time to Visit Hakone for Ideal Weather
Hakone’s weather changes a lot from season to season, so the best time to visit really depends on what you’re hoping to do. Mild temps, low humidity, and clear skies make certain months stand out, and seasonal highlights like cherry blossoms or autumn leaves give each visit a unique feel.
Most Pleasant Months for Outdoor Activities
Late March to May and late September to November seem to offer the best weather for being outside. Daytime highs usually land between 15°C and 22°C (59°F to 72°F), which is perfect for walking, hiking, or taking a lake cruise.
Spring and autumn also bring down the humidity, so you can hit Hakone’s trails without feeling sticky. Skies tend to be clearer too, especially in the mornings, so your chances of seeing Mount Fuji go way up.
If you’re looking to soak in a hot spring but don’t want to freeze or sweat, these months feel just right. The cool air makes the baths extra relaxing, way better than in the muggy summer or icy winter.
Peak Cherry Blossom and Autumn Foliage Periods
Cherry blossoms bloom a bit later in Hakone than in Tokyo because it’s higher up. You’ll usually catch them from early April to late April, and some spots keep blooming into early May. The Hakone Tozan Railway, Miyagino riverside, and Onshi Hakone Park are all local favorites for viewing.
For autumn, late October through late November is the sweet spot. The mountains light up in red, orange, and yellow, and the views over Lake Ashi or by Owakudani’s volcanic steam are just stunning. You can even enjoy the colors from an open-air hot spring—honestly, that’s pretty special.
Both cherry blossom and fall foliage seasons draw bigger crowds, so hotels fill up and trains get packed. If you want to dodge the busiest times, aim for early mornings or visit on weekdays.
Impact of Rainy and Typhoon Seasons
Hakone’s rainy season runs from mid-June to mid-July. Hydrangeas bloom everywhere, which is lovely, but the steady rain can make hiking tricky. Trails get muddy, and good views of Mount Fuji are rare.
Typhoon season peaks from August to early October. Not every storm hits Hakone, but when they do, heavy rain and strong winds can mess with travel plans. Trains and the ropeway sometimes shut down during bad weather.
If you’re set on coming in summer, just pack solid rain gear and plan for some indoor time—maybe museums or hot spring resorts. That way, you’ll still have fun even if the weather goes sideways.
Seasonal Breakdown: What to Expect in Each Season
Hakone’s seasons shape your trip in big ways. The weather decides how you’ll experience the hot springs, mountain scenery, and those epic views of Mount Fuji.
Spring in Hakone: Cherry Blossoms and Mild Weather
Spring in Hakone lasts from March to May, with daytime temps at 10–20°C (50–68°F). It’s mild and super comfortable for being outdoors.
Cherry blossoms bloom in stages because of the different elevations. Lower areas like Hakone Yumoto see blossoms first, while higher spots like Gora bloom later. That means you get a longer season than Tokyo.
People love spots like Miyagino Hayakawa Embankment, which has over 100 cherry trees, and Onshi Hakone Park, where you can see blossoms with Mount Fuji behind them. The Hakone Tozan Railway even passes through short “tunnels” of blossoms—try to ride early in the morning for fewer crowds.
April can bring some rain, so bring a light jacket and an umbrella. Evenings feel cool, especially higher up.
Summer in Hakone: Warm Temperatures and Rain
Summer runs from June to August. Daytime highs hit 25–28°C (77–82°F), which is about 5 degrees cooler than Tokyo, but the humidity is high. June is the rainy season, and late summer can bring typhoons, so expect sudden showers.
Despite the rain, lots of people come for hiking, boating on Lake Ashi, and forest walks. Cooler mornings and evenings are great for getting outside. You can also catch fireworks festivals over Lake Ashi, which look amazing reflected on the water.
If you want to escape the heat, check out higher spots like Owakudani or ride the Hakone Ropeway for stronger breezes. Museums and indoor attractions come in handy on hot or rainy days.
Bring light, breathable clothes, a rain jacket, and sturdy shoes—trails get slippery after it rains.
Autumn in Hakone: Foliage and Comfortable Climate
Autumn goes from September to November. Temps are 10–20°C (50–68°F), with crisp mornings and mild afternoons. Rain drops off, and the air gets clearer, so you have a better shot at seeing Mount Fuji.
The autumn leaves are the highlight. Colors peak from late October to late November, painting the mountains in reds and yellows. Try Owakudani for views with volcanic steam, or walk along Lake Ashi for reflections of the trees.
Open-air hot springs feel especially good now. The cool air and warm baths make evenings really pleasant. You’ll want a light jacket for the evenings, but daytime layers usually do the trick.
Winter in Hakone: Crisp Air and Snowy Views
Winter stretches from December to February. Daytime highs sit at 5–10°C (41–50°F), and nights get close to freezing. Snow isn’t constant but falls a few times each winter, especially higher up.
The cold brings some of the clearest skies all year, so it’s a great time to catch views of Mount Fuji from Lake Ashi or the ropeway. The air feels sharp, and snow on the scenery adds a cozy vibe.
Hot springs are a big draw in winter. Bathing outside while snow falls around you is pretty unforgettable. Seasonal illuminations at gardens and museums also brighten up the long nights.
Bring warm clothes, gloves, and a hat. The wind can make it feel colder, especially in open areas.

Humidity and Sunshine Hours by Month
Humidity really shapes Hakone’s weather. From June through September, the air feels heavy and damp, especially during the rainy season. That makes summer days seem warmer than they actually are.
Winter months bring much lower humidity, so you get crisp, clear conditions. You’ll also see more sunshine then, compared to the cloudier summer months.

Snowfall and Dry Days Statistics

How Weather Influences Hakone Travel Experiences
Weather really shapes your time in Hakone. Clear skies can give you those perfect Mt. Fuji views, and the season affects how comfortable it feels to wander around outside. Conditions shift with both the time of year and the elevation, so checking climate patterns helps you plan a smoother trip.
Best Weather for Sightseeing and Outdoor Attractions
Spring and autumn tend to have the nicest weather for walking, hiking, and exploring Hakone’s outdoor spots. In spring, you get mild temps and cherry blossoms, especially around Hakone Yumoto and Gora.
Autumn brings cool air and colorful leaves, which look especially beautiful from the Hakone Tozan Railway.
Summer feels humid, but the higher spots near Lake Ashi stay cooler than Tokyo. That makes a Lake Ashi Cruise or a stop at the Hakone Open-Air Museum a lot more comfortable.
Still, don’t forget the rainy season in June and the typhoons that sometimes pop up in late summer. They can mess with your outdoor plans.
Winter means colder weather, but you usually get clear skies and great visibility. Walking outside might not feel as cozy, but hot springs and indoor attractions help balance out the chill.
Seasonal Highlights: Lake Ashi, Hot Springs, and Museums
Each season changes how you’ll experience Hakone’s top attractions. Lake Ashi draws people all year, and sightseeing cruises show off the mountains around you.
Spring and summer cruises feel cool and breezy. In autumn, the lake reflects all those bright red and gold leaves.
Hot springs, or onsen, really shine when it’s cold out. Sitting in a steaming outdoor bath while the air chills your face is a winter highlight. Gora and Sengokuhara have some of the best spots for this.
Rainy days or bad weather? The Hakone Open-Air Museum and other art museums give you solid backup plans. These places work well any time of year, with both indoor and outdoor art that fits whatever the weather throws at you.
Visibility of Mount Fuji by Season
Your odds of seeing Mount Fuji change with the seasons. Winter almost always brings the clearest skies, and the dry air lets you catch the peak from Lake Ashi and other viewpoints. It’s the top season for photos.
Spring and autumn aren’t bad either, but clouds can roll in fast, especially after noon. You’ll have your best shot in the morning.
Summer is tough for Fuji views. Humidity, haze, and lots of rain often hide the mountain. So if seeing Mount Fuji matters most, aim for the cooler, drier months.
Practical Tips for Planning Your Visit
Hakone’s weather switches up a lot between seasons. You’ll want to plan your clothes, booking, and even your route with the weather in mind. That way, you can relax and enjoy Kanagawa Prefecture’s famous hot springs without extra hassle.
What to Pack for Each Season
In spring (March–May), bring a light jacket, some layers, and comfy walking shoes. Nights can get chilly, especially up in Gora. Toss in a small umbrella just in case.
For summer (June–August), expect warm, humid days, but Hakone runs cooler than Tokyo. Breathable clothes, a hat, sunscreen, and maybe some bug spray if you’re hiking are all good ideas.
Autumn (September–November) calls for warmer layers. A fleece or sweater helps with those brisk mornings, and sturdy shoes keep you steady on leafy paths.
In winter (December–February), it gets cold and you might see some snow at higher spots. Pack a warm coat, gloves, and shoes or boots with good grip. If you’re heading to outdoor hot springs, quick-dry clothes and extra socks come in handy.
Crowd Levels and Accommodation Considerations
Hakone draws a lot of visitors from Tokyo, and crowd sizes swing a lot depending on the season. Golden Week in spring, Obon in summer, and the autumn leaf season pack the biggest crowds. Trains, buses, and ropeways get busy fast, and ryokans often fill up months ahead.
If you want a quieter trip, try coming on weekdays or in winter when things slow down. Early mornings also give you a calmer vibe at places like Lake Ashi or Owakudani.
Book your stay early if you want a private onsen or a room with a lake view. Smaller guesthouses in Hakone Yumoto or Sengokuhara sometimes have more openings during busy times. You might have better luck staying just outside the main areas and using local transport to get around.
Weather-Related Travel Advice
Hakone sits in the mountains, so the weather changes fast. June and July bring plenty of rain, so check the forecast and toss some waterproof gear in your bag.
Typhoons sometimes roll through in late summer or early autumn. They can shut down ropeways or hiking trails for a bit, which is always a hassle.
Winter brings snow that can mess with roads and bus routes, especially near Owakudani or up in the higher areas. If you’re driving, you’ll need winter tires or chains—no exceptions.
Public transport usually keeps running, but you might want to give yourself extra time just in case.
When the air’s clear in winter, you’ll get those amazing Mount Fuji views. Summer, though, often comes with haze that can really limit what you see. If sightseeing is high on your list, it’s something to keep in mind.
Always double-check the schedules for boats, ropeways, and trains before you head out. It’s just better that way.
