Sento-Run : Jog and bath in the heat of Tokyo

Where to jog, breathe fresh air, and relax in the heart of Tokyo

Tokyo is a city of contrasts—a place where ultramodern skyscrapers stand beside historic temples, and neon-lit streets give way to serene green spaces. While the metropolis is known for its fast-paced energy, it also offers hidden pockets of tranquility, perfect for those seeking a break from the urban rush.

If you're looking for a spot to jog, take in fresh air, and relax in the middle of Tokyo, there’s a place that might surprise you: Sotobori Park. Tucked away near the Imperial Palace, this park is not as widely known among tourists, making it a local favorite for runners, walkers, and anyone craving a peaceful escape.

Unlike Tokyo’s more crowded parks, Sotobori Park remains relatively quiet, especially in the mornings. On weekdays, you'll mainly find university students and nearby residents enjoying a stroll along its scenic paths. The weekends bring a bit more activity, but in the early hours, the park is a haven of calm—a perfect setting for a solo run or a moment of reflection amidst nature.

But what makes this park truly special is how it transforms with the seasons. In early spring, the landscape bursts into color as cherry blossoms bloom, drawing people in for hanami (cherry blossom viewing). Suddenly, the usually tranquil paths fill with groups gathered under the pink canopy, enjoying picnics and celebrating the fleeting beauty of the season. Jogging during this time becomes an entirely different experience—less about pace and more about soaking in the breathtaking scenery.

Whether you’re a runner, a casual walker, or simply someone looking for a peaceful retreat in Tokyo, Sotobori Park offers a unique blend of history, nature, and relaxation. In the next section, we’ll explore the best times to visit, the highlights of each season, and how to make the most of your time in this hidden oasis.

 

From Yotsuya Station: A scenic route through history and nature.

Yotsuya is a fascinating district in Tokyo, uniquely positioned between the modern hustle of Shinjuku and the historic grandeur of the Imperial Palace. Unlike many parts of the city, Yotsuya features wide-open roads with uninterrupted views, a rare sight in Tokyo’s dense urban landscape.

Your run begins at Yotsuyamitsuke Bridge, where you’ll head toward the State Guest House, Akasaka Palace—a striking building that resembles a 19th-century European château. This magnificent structure serves as a residence for world leaders and diplomats visiting Japan.

As you continue, don’t be surprised to see a line of taxis crowding the main road—most of them are heading to Akasaka, one of Tokyo’s vibrant nightlife districts. Stay focused on your run, and when you reach the red light, look to your right. You’ll spot a massive wooden gate guarded by police officers—this is your cue to cross the bridge on your left. From here, your journey takes a beautiful turn as you enter the Sakura Path, a scenic stretch lined with cherry trees that offer breathtaking views, especially in spring.

    

To your right, you’ll notice a steep slope leading down to a sports field, where Sophia University students often practice rugby and soccer. Just a little farther ahead, Yotsuya Station comes into view. At this point, cross Yotsuyamitsuke Bridge again, staying on the left side. Head up to the walking path, where you’ll pass through a lush park filled with a variety of trees and plants—a welcome green oasis in the city. Soon, you’ll catch the first glimpse of the water moat, signaling that you’re nearing Ichigaya Station.

            

From Ichigaya Station: A tranquil riverside escape

Ichigaya is a charming district with a unique feature—a mini fishing pond right next to the station. Here, locals and visitors alike try their luck at catching carp and goldfish, adding a nostalgic touch to the area. From your elevated running path, you can look down at the pond, watching the slow movements of the fish beneath the water’s surface.

This part of the run is particularly magical in spring and autumn, as you’ll be running under massive, centuries-old cherry blossom trees. Their branches arch over the path, creating a tunnel of petals in spring, while in autumn, the golden hues add warmth to the crisp air.

As the sun sets, the soft glow of the waterside café lights up the scenery, making for an incredibly romantic atmosphere. Whether you're jogging or simply taking a moment to pause, Ichigaya at night is a sight to behold.

    

From Iidabashi Station: The final stretch into Edo’s past

Reaching Iidabashi Station marks the last leg of your run, but the journey isn't over just yet. Take the slope next to Starbucks, and you’ll find yourself in Kagurazaka, a district steeped in old Edo charm. This area exudes a nostalgic yet sophisticated ambiance, with its narrow stone-paved alleys, traditional wooden shops, and historic temples creating a distinctly Japanese atmosphere.

On the left, you’ll pass by quaint stores and artisan boutiques, perfect for a leisurely stroll after your run. The deeper you venture, the more you’ll feel transported back in time, surrounded by the quiet elegance of Kagurazaka’s traditional ryotei (Japanese restaurants) and teahouses.

Finally, as you reach the top of the slope, your destination awaits. Look to your right—you’ll spot the bathhouse, nestled next to a set of vending machines. Congratulations! You’ve completed a journey through one of Tokyo’s most scenic and culturally rich running routes.

Now, take a deep breath, cool down, and perhaps reward yourself with a relaxing soak in the bathhouse—a perfect way to end your run in true Japanese style.
