The Imperial Palace 5km Run

Just a short trip from the modern comforts of LOF HOTEL Shimbashi, the Imperial Palace Run (皇居ラン, often called the Kokyo Run) offers something rare in a megacity: a perfectly measured circuit through the capital’s historic core. The city’s frantic pace eases into wide sidewalks, ancient moats, stone walls, and greenery, with skyscrapers framing the Imperial Palace grounds. It is a sanctuary in the city—beloved by marathoners, office workers on lunch runs, and first-timers who want to feel Tokyo like a local.

On busy days thousands of runners share the loop. The course is almost exactly 5km with only modest elevation (roughly 30 meters). There are no traffic lights along the main circuit, so you can settle into a steady rhythm. The route is meant to be run counter-clockwise—everyone moves the same way, which keeps the flow predictable and safe.

Along the way you pass landmarks such as Sakuradamon Gate, the moats of Chidorigafuchi, the Nippon Budokan, and views toward Tokyo Tower and the National Diet Building. In spring, parts of the path rank among Tokyo’s best cherry-blossom walks. Look down, too: the path includes “flower plates” marking the official flower of each of Japan’s 47 prefectures—a small scavenger hunt beneath your feet.

Etiquette matters because the path is a sidewalk shared with pedestrians, not a private track. Yield to walkers, go single file on narrow stretches (especially near Chidorigafuchi), keep headphone volume low enough to hear bicycles and others, and use water fountains and restrooms at points such as Sakuradamon and Takebashi when you need them.

You do not have to carry a full kit. The Marunouchi and palace area are dotted with running stations (Run-stes)—paid facilities for bag storage, rental wear, and showers. Marunouchi Bike & Run in the Shin-Marunouchi Building (linked to Tokyo Station) and Asics Run Tokyo Marunouchi are well known. For a classic Japanese wind-down, some runners visit a sento such as Inari-yu (featured in Thermae Romae). Budget roughly ¥1,000 for a straightforward run-ste style package.

LOF HOTEL Shimbashi sits at 5-23-4 Shimbashi, so reaching the loop is simple. From JR Shimbashi Station (about an eight-minute walk from the hotel), take the Yamanote Line one stop to Yurakucho and walk to the palace, or take the Tokyo Metro Chiyoda Line from Shimbashi to Nijubashimae (Exit 6) for a doorstep drop at the outer grounds. One-way metro fares are typically around ¥180.

If you prefer to warm up on foot, it is roughly 2.1km from the hotel to the Sakuradamon side—about 25 minutes at a brisk walk before you start your lap. A taxi to the Sakuradamon area usually takes around eight minutes and costs about ¥1,200–¥1,500; ask for “Kokyo no Sakuradamon” (皇居の桜田門).

Early mornings (around 7–8 AM) offer cooler air and thinner crowds; evenings reward you with skyline light. The route is lit and frequented enough that many locals are comfortable after dark, but use the same judgment you would in any big city.

On your next morning in Tokyo, consider trading only the subway map for running shoes once: the Imperial Palace loop is a healthy, memorable way to touch the center of the city—whether you run the full 5km or simply stroll a segment with a coffee in hand.
