1. Hakone, Kanagawa Prefecture
Why Hakone is Perfect for Relaxation
Nestled just a short train ride from Tokyo, Hakone is arguably one of Japan’s most famous onsen towns—and for good reason. Surrounded by lush forests, volcanic hills, and breathtaking views of Mount Fuji, Hakone offers the perfect combination of relaxation, natural beauty, and cultural charm.
Hakone’s history as a hot spring resort dates back over 1,200 years. During the Edo Period, it served as a popular rest stop along the Tokaido Road, a major travel route between Tokyo and Kyoto. Travelers would soak in the healing waters of Hakone’s onsens to rejuvenate their weary bodies before continuing their journeys.
Top Ryokan and Private Onsen in Hakone
Hakone is home to countless ryokan (traditional Japanese inns) offering private onsen baths—a perfect option for couples or those seeking privacy.
- Gora Kadan: A luxurious ryokan set in a former imperial villa, Gora Kadan offers exquisite private open-air baths and top-notch service. The ryokan seamlessly blends modern elegance with traditional Japanese aesthetics.
- Yama no Chaya: Located in the mountains, Yama no Chaya features open-air private baths surrounded by lush greenery, offering an intimate and tranquil setting.
- Hakone Suimeisou: Situated near Hakone Yumoto Station, Suimeisou offers rooms with private open-air baths overlooking the river, perfect for a relaxing soak after a day of sightseeing.
For budget-conscious travelers, many public bathhouses like Tenzan Onsen and Hakone Yuryo provide affordable yet relaxing experiences with their natural spring waters.
Outdoor Activities to Complement Your Onsen Experience
Beyond its onsens, Hakone boasts a variety of activities and natural wonders that complement a relaxing getaway:
- Lake Ashi: Take a scenic boat cruise on Lake Ashi, where you’ll enjoy stunning views of Mount Fuji reflected in the calm waters. For an added touch, hop on one of the pirate ships that sail across the lake.
- Hakone Ropeway: Ride the ropeway up to Owakudani, an active volcanic valley. Along the way, you’ll witness steaming vents and sulfuric clouds, giving you a glimpse of the region’s geothermal power.
- Hakone Shrine: Nestled at the edge of Lake Ashi, the iconic red torii gate of Hakone Shrine is one of the area’s most photographed landmarks. Visit early in the morning for a peaceful, crowd-free experience.
- Hakone Open-Air Museum: Art lovers will appreciate this outdoor museum, which features sculptures and installations surrounded by stunning natural landscapes. Don’t miss the Picasso Pavilion!
Seasonal Beauty of Hakone
Hakone’s landscape transforms beautifully with each season, making it a year-round destination:
- Spring: Cherry blossoms bloom along the riverbanks, creating a pastel paradise perfect for leisurely strolls.
- Summer: Lush green forests and cooler mountain temperatures provide a refreshing escape from Japan’s summer heat.
- Autumn: Vibrant fall foliage covers the mountains and lakesides, turning Hakone into a breathtaking kaleidoscope of reds, oranges, and yellows.
- Winter: Snow-dusted landscapes and views of Mount Fuji create a tranquil, picturesque setting for soaking in an outdoor onsen.
Why Hakone Stands Out
Hakone offers the perfect blend of traditional Japanese culture, stunning scenery, and modern comforts. Whether you’re indulging in a luxurious ryokan stay, exploring volcanic valleys, or taking in Mount Fuji’s beauty, Hakone has something for everyone.
