The picturesque and relaxing getaway of Hakone in Kanagawa Prefecture sits at the base of Mount Fuji, rich with beautiful views and surrounding nature. The fresh and open air of this area makes it a great place to visit from nearby Tokyo, especially during summer. Take a look at our warm-weather recommendations for the area!
Climbing Mount Fuji
Summer marks the official climbing season for Mount Fuji, Japan’s highest and most sacred mountain. Standing at 3,776 meters, the volcano attracts hikers from around the world who come to witness the unforgettable sunrise from its summit. The trails are generally open from early July to early September, when weather conditions are safest and mountain facilities are operating.
Several routes lead to the top, each offering different levels of difficulty and scenery. Even if you are not ready for the full ascent, it is still possible to enjoy the mountain by visiting the famous Fifth Station, where panoramic views, souvenir shops, and hiking paths provide a taste of the Fuji experience without requiring a strenuous climb.
For adventurous travelers, climbing overnight to see the sunrise is an unforgettable experience. Cooler mountain temperatures also make Fuji a refreshing escape from Japan’s summer heat.

The Ashinoko Kosui Matsuri Festival
Among Hakone’s many summer traditions, the Ashinoko Kosui Matsuri Festival is one of the most spectacular. Held every year on July 31 around Lake Ashi, the festival celebrates the legend of the nine-headed dragon said to have once lived beneath the lake’s waters.
According to local folklore, the dragon terrorized nearby villagers until a Buddhist monk subdued the creature and transformed it into the guardian spirit of Hakone. Today, the festival honors this legend with religious ceremonies at Hakone Shrine, where priests present offerings of sake and red rice to the dragon deity.
Throughout the evening, the lakeside comes alive with festival stalls selling local specialties and summer street food, while traditional music and performances create a festive atmosphere. The highlight of the night is the magnificent fireworks display, whose colorful reflections shimmer across the calm waters of Lake Ashi.
A Walk Through Moto Hakone
Nestled along the shores of Lake Ashi, the charming village of Moto Hakone offers some of the region’s most beautiful scenery. This peaceful lakeside area is ideal for a relaxing day surrounded by forests, historic landmarks, and stunning views of Mount Fuji.
Begin your visit at the historic Hakone Shrine, founded during the Heian period (794–1185). Hidden deep within towering cedar trees, the shrine is famous for its striking red torii gate standing in the water at the edge of the lake. The quiet forest paths and lantern-lined approach create a magical atmosphere, especially in the early morning or late afternoon.
From there, continue along the ancient cedar avenue toward Onshi Hakone Park, a former imperial villa site offering some of Hakone’s finest panoramic views. On clear summer days, you can admire Lake Ashi stretching out below with Mount Fuji rising in the distance.

Relax at an Onsen
No trip to Hakone would be complete without experiencing one of its famous onsen, or natural hot springs. Thanks to the region’s volcanic activity, Hakone is home to countless hot spring resorts, ranging from traditional ryokan baths to modern spa complexes.
Soaking in an outdoor bath surrounded by forested mountains is one of the most relaxing ways to unwind after a day of sightseeing or hiking. The mineral-rich waters are said to help relieve fatigue and improve circulation, making them especially welcome after climbing Mount Fuji or exploring the Hakone countryside.
Discover Hakone’s Museums and Art Spaces
Hakone is not only famous for its mountains and hot springs—it is also one of Japan’s premier destinations for art lovers. Surrounded by forests and open-air landscapes, the region’s museums offer a refreshing cultural escape during the summer months, especially on warmer afternoons.
One of the most famous is the Hakone Open-Air Museum, where contemporary sculptures are displayed across beautifully landscaped gardens against a backdrop of green mountains.

The combination of art and nature creates a uniquely relaxing atmosphere, and visitors can stroll through the outdoor exhibits while enjoying the fresh mountain air. The museum also features works by renowned artists such as Pablo Picasso, as well as interactive installations that children and adults alike can enjoy.
Another must-visit is the Pola Museum of Art, hidden within a peaceful forest area. Known for its impressive collection of Impressionist paintings, Japanese art, and modern works, the museum is equally admired for its elegant architecture and serene woodland walking paths. Large glass windows allow natural light to flood the galleries, creating a calm and immersive experience.
