Hakone: Hot Springs, Lake Ashi, and the Volcanic Valley of Owakudani

Updated October 24, 2026 | By Tokyo Paul

Hakone is a mountain town in Kanagawa Prefecture, known for its hot springs, lake scenery, and art museums. It is a popular escape from the city, and it works well as a day trip or an overnight stay. This guide draws on Wikipedia's article about Hakone and adds planning advice, including safety notes for hot springs and volcanic areas. Conditions can change, and some areas may close because of volcanic activity or weather, so check official notices before you go and follow local instructions.

Where Hakone Is

Wikipedia describes Hakone as a town in Kanagawa Prefecture. It says the town is in the mountains in the far west of the prefecture, on the eastern side of Hakone Pass. Most of the town lies within the borders of the volcanically active Fuji-Hakone-Izu National Park, centered on Lake Ashi. That description gives a clear picture: this is mountain country, with a lake and volcanic landscape.

A Spa Town

The article calls Hakone a notable spa town and a popular tourist destination because of its many hot springs. It adds that the hot springs are within view of nearby Mount Fuji. It also says the economy of Hakone is strongly dominated by the tourist industry. That is useful to know when planning, because many services are geared toward visitors, though weekends and holidays can still be busy.

Owakudani

The article lists the volcanically active Owakudani fumaroles as a sight, and says Owakudani can be reached by the Hakone Ropeway from Sounzan and the lake. Volcanic areas can be affected by gas and changing conditions, and access may be restricted at short notice. Before you go, check the latest information from official sources, and follow all signs and staff instructions. People with respiratory problems, heart conditions, or other health concerns should consult a doctor before visiting areas with volcanic gases.

History on the Road

According to Wikipedia, Hakone-juku was a post station on the Tokaido highway connecting Edo with Kyoto. The article also mentions Hakone Gongen, a noted Shinto shrine mentioned in Heian-period literature. These details show that Hakone was a place travelers passed through long before it became a resort.

Art and Culture

Hakone has a number of art museums, including the Hakone Open-Air Museum and the Pola Museum of Art, according to the article. If the weather is poor, a museum visit can be a good alternative to outdoor sightseeing. Check opening hours and any ticket requirements in advance.

Population and Pace

The article gives the town's population as 10,965, and says that it peaked around 1970 and has declined since. A small permanent population means a modest local community, so be considerate of residents, especially in quiet neighborhoods.

Using the Hot Springs Safely

Hot springs are a highlight, but they deserve care. Here are general suggestions. These are not medical advice, and you should consult a doctor if you have health concerns.

Follow the posted rules at each facility, including those on washing before entering.
Drink water before and after bathing.
Avoid bathing right after eating or while drinking alcohol.
Enter and leave the water slowly to avoid dizziness.
Take breaks if the water feels too hot, and leave if you feel unwell.
If you have a heart condition, high or low blood pressure, or are pregnant, ask a doctor first.
Warm the changing area if you can, because sudden temperature changes can be stressful for the body. Our article on bathing safety in Japan explains heat shock in more detail, citing a Nippon.com report.

A Sample Day Plan

For a day trip, pick two or three activities rather than trying to do everything. You might spend the morning on a lake-area walk, have lunch, visit a museum in the afternoon, and finish with a hot spring before heading back. Check transport timetables in advance, including the ropeway if you plan to use it, since services can pause for weather or maintenance.

Packing Tips

Layers, since mountain weather can change.
Comfortable walking shoes.
A small towel for hot spring visits, if not provided.
Water and snacks.
A compact umbrella.
A phone with a charged battery and offline maps.
Any regular medication, if you plan an overnight stay.

Choosing Between a Day Trip and an Overnight Stay

A day trip is simple and affordable, but it can feel rushed once you count travel time, transfers, and queues. An overnight stay gives you a slower rhythm: you can arrive, rest, enjoy an evening soak, and wake up without an alarm. If you have the time, even a single night changes the feel of the trip. If you only have a day, accept that you will not see everything, and choose a theme, such as hot springs and a museum, or lake views and a short walk.

Whichever you choose, confirm transport options before you leave, keep some buffer time in your schedule, and make sure you know the last return connection. Mountain services can be affected by weather, so have a backup plan.

Respecting the Place

Hakone's popularity means it can get crowded. Be patient on transport, keep your voice down in shared spaces, and follow the rules at hot springs and museums. If you take photographs, do so without blocking paths or photographing other bathers.

Geography and Climate From the Source

Wikipedia says Hakone lies in the mountains of the far west of Kanagawa Prefecture, on the eastern side of Hakone Pass, and that most of the town sits within Fuji-Hakone-Izu National Park, which is centered on Lake Ashi. The page gives the town a humid subtropical climate, with an average annual temperature of 13.3 degrees Celsius and average annual rainfall of 2221 millimeters. A mountain town with that much rain deserves a plan for wet weather, so pack a compact umbrella or a light rain jacket.

A Checkpoint on the Old Highway

According to the article, Hakone-juku was a post station on the Tokaido highway linking Edo and Kyoto. The Hakone Checkpoint marked the border of the Kanto region, where officials examined travelers for permits and baggage under laws restricting the travel of women and weapons. The page says the town became a town in 1889, and reached its present boundaries after a September 1956 merger with five neighboring towns and villages.

Museums and Culture

The page mentions several art museums, including the Hakone Open-Air Museum and the Pola Museum of Art. It also says the Hakone Ekiden, a collegiate long-distance race, is held at New Year and runs from Tokyo to Hakone and back over two days. If your trip is in early January, check the route and road closures, since events like this can affect traffic and crowds.

Getting There From Shinjuku

The article says the Odakyu Odawara Line runs about 70 minutes from Shinjuku to Odawara, and that the Hakone Tozan Line continues from Odawara into the resort towns. Travel times and timetables change, so check a current route planner. Build in extra time for transfers, especially on weekends and holidays, and make sure you know the last return train before you head up the mountain.

An Economy Built on Visitors

The page says the town's economy is strongly dominated by tourism, and that its sights include the volcanically active Owakudani fumaroles. It also says the census population peaked around 1970 at 21,299 and has declined since. Remember that you are visiting a place where people live and work. Keep your voice low near residences, follow posted rules, and use public transport thoughtfully when roads are busy.

A Note on Volcanic Areas

Volcanic zones can change conditions quickly. Follow official closures and alerts, obey signs and barriers, and do not enter restricted areas. If you have breathing difficulties or a heart condition, check with a doctor before visiting areas with volcanic gas, and consider skipping them. Install and review the official Safety tips app before you travel, and check local information on the day of your visit.
