Karuizawa’s Ultimate Guide: 5 Enchanting Spots Where History and Nature Weave Their Magic

Japan’s premier summer resort, Karuizawa continues to enchant countless travelers. It’s a special area where a rich natural environment intertwines with a history of development by foreign missionaries and a refined culture cultivated as a villa retreat.

In this article, we’ve carefully selected five major spots you absolutely must visit in Karuizawa. Beyond textbook information, we’ll delve into the deep origins of each place and provide ‘real-world strategies’ to avoid crowds and enjoy the local atmosphere to 120%.

Shiraito Falls

📍 Address: Nagakura, Karuizawa-machi, Kitasaku-gun, Nagano 389-0111, Japan

Shiraito Falls, a symbol of Karuizawa’s pristine nature, is an elegant, breathtaking spot where countless thin streams of water cascade like silk threads over a curved rock face, approximately 3 meters high and 70 meters wide.

Remarkably, this waterfall isn’t formed by a river, but by a very rare mechanism called a ‘subsurface waterfall’ (senryu-baku). Rain and melted snow from Mount Asama infiltrate underground, taking about six years to seep out through fissures in the geological strata. This unique process ensures that the water remains clear and pristine, even after heavy rainfall.

While you might expect a more dynamic, grand waterfall, the true charm of this place lies in its ‘tranquility and healing.’ Immerse yourself in the negative ions from the spray and enjoy a garden-like landscape integrated with the forest trees.

As a practical tip for travelers, while the path to the waterfall is short and easy to walk, during winter and early spring, it can be icy or muddy due to melting snow. Therefore, comfortable shoes like sneakers are essential. Also, remember that you’ll need to pay a toll for the Shiraito Highland Way (toll road) to access it.

Harunire Terrace

📍 Address: 2145ｰ5 Nagakura, Karuizawa-machi, Kitasaku-gun, Nagano 389-0111, Japan

Harunire Terrace, located in the Hoshino Area of Naka-Karuizawa, is a highly popular commercial facility conceptualized as ‘Karuizawa’s everyday life.’ Its design masterfully harmonizes with the surrounding forest, featuring wooden decks built around over 100 native Japanese elm trees (harunire) that grew along the clear Yu River, without cutting any of them down and utilizing the natural topography.

The facility is home to an array of Karuizawa’s renowned establishments. With 16 shops, including the famous Shinshu soba restaurant ‘Kawakami-an,’ ‘Maruyama Coffee’ known for its specialty coffee, and a bakery praised for its exquisite flavors, you’re guaranteed a delightful experience no matter where you choose to go.

The secret to enjoying this place to its fullest is to aim for ‘morning hours.’ From noon to evening, it becomes bustling with tourists, leading to severe traffic jams that make even entering the parking lot difficult. However, in the early morning, enveloped by the crisp forest air and the murmuring of the river, you can savor a graceful breakfast with freshly baked bread and coffee. Many terrace seats are pet-friendly, making it an excellent spot for dog lovers too.

Kyu-Karuizawa Ginza Shopping Street

📍 Address: 878 Karuizawa, Karuizawa-machi, Kitasaku-gun, Nagano 389-0102, Japan

The main street for Karuizawa sightseeing is the ‘Kyu-Karuizawa Ginza Shopping Street.’ This area, which flourished as the ‘Karuizawa-shuku’ on the Nakasendo road during the Edo period, saw significant development as a Western-influenced summer resort after Canadian missionary A.C. Shaw was captivated by its cool climate and built a villa here in the Meiji era.

Once lined with shops catering to foreign villa residents, the street is now a haven for street food and shopping. Don’t miss the long-established jam shops, authentic sausages from Chozume-ya, and especially the ‘Moccha Soft’ (mocha soft serve ice cream) from ‘Mikado Coffee.’ With a taste of these historic delights in hand, you can leisurely enjoy the slightly retro, exotic townscape on its pedestrian-only street.

While the main street is lively, stepping into a side alley reveals charming churches enveloped in tranquility and historical tennis courts, adding to the appeal of this area. If you’re arriving by car, it’s wise to research parking lots with maximum daily rates in advance, depending on your stay duration. Parking a little further away and exploring the surroundings by rental bicycle is also a quintessential Karuizawa experience.

Important Cultural Property Old Mikasa Hotel

📍 Address: 1339−342 Karuizawa, Karuizawa-machi, Kitasaku-gun, Nagano 389-0102, Japan

The ‘Old Mikasa Hotel’ is indispensable when discussing Karuizawa’s history. Founded in 1906 (Meiji 39) by businessman Naoyoshi Yamamoto, this hotel is a purely Western-style wooden building, designed and constructed entirely by Japanese hands. Boasting top-tier facilities for its time, such as gas lamp-style chandeliers and British-made carpets, it was a gathering place for political and financial magnates and cultural figures, earning it the moniker ‘Rokumeikan of Karuizawa.’

After a long period of extensive seismic reinforcement and preservation repair work, it finally celebrated its highly anticipated ‘renewal opening’ on October 1, 2025. The beautifully revived interior now includes added elevators and barrier-free restrooms, ensuring everyone can visit safely.

A highlight of the renewal is the newly established ‘CAFE MIKASA HOTEL 1906’ where visitors can savor the famous European-style curry and sweets, recreated from original recipes, in a retro ambiance. Additionally, a ‘Retro Costume Experience’ has begun, allowing guests to explore the hotel in Meiji and Taisho era costumes, transforming it into an immersive spot where you can delve deeper into historical romance.

Kumoba Pond

📍 Address: Karuizawa, Karuizawa-machi, Kitasaku-gun, Nagano 389-0102, Japan

If you want to fully enjoy Karuizawa’s nature, ‘Kumoba Pond’ is a must-visit. This artificial pond was created in the Taisho era by businessman Genjiro Nozawa, who dammed the ‘Gozen-sui (Kumoba River)’ – spring water that had long been used for the meals of feudal lords and imperial families. Due to the swans that once frequented it, foreign summer visitors affectionately called it ‘Swan Lake.’

A unique local legend also tells that the pond is the footprint left by a giant named ‘Daylanbo’ when he stumbled while creating Mount Asama.

A walking path of approximately 1 km is maintained around the pond, allowing you to complete a full loop in about 20-30 minutes. In early summer, the fresh greenery is vibrant, and in autumn, maple and enkianthus trees turn red and yellow, creating a breathtaking spectacle where the autumn leaves reflect on the mirror-like water surface. After rain or snow, the path can become muddy, so it’s best to wear shoes that you don’t mind getting dirty, such as sneakers. Renting a bicycle from Karuizawa Station and cycling while admiring the luxurious villa areas is also a highly recommended way to access the pond.

Real-World Tips for Maximizing Your Karuizawa Trip

Finally, we’ll share some advice for enjoying Karuizawa sightseeing without stress and in greater depth. Many areas in Karuizawa have narrow roads, and during high season (summer holidays, autumn foliage season, long weekends, etc.), major roads and parking areas around popular spots experience severe traffic jams.

The biggest secret to avoiding these traffic jams and crowds is to prioritize ‘early morning activities.’ Natural spots like Harunire Terrace’s bakeries and cafes, Shiraito Falls, and Kumoba Pond are accessible early in the morning, so it’s a golden rule to visit the main attractions in the morning. For the afternoon, dedicate your time to historical exploration at ‘Old Mikasa Hotel’ or museum visits, which might require advance reservations or have sufficient capacity, ensuring a smooth day.

Additionally, renting a bicycle near Karuizawa Station is highly effective. Moving around Kyu-Karuizawa Ginza and Kumoba Pond by bike is incredibly convenient, and cycling through the dappled sunlight is an excellent activity in itself. In Karuizawa, where history and nature intertwine, we hope you create your own wonderful memories.
