Located in the heart of Tokyo, the Tokyo Imperial Palace covers approximately 3.4 square kilometers, making it the largest green space in central Tokyo and the only imperial residence situated in a major metropolitan area worldwide. This area also encompasses the ruins of Edo Castle and carries modern significance for the Japanese imperial family. The running route spans approximately 5 kilometers, with over 10,000 runners on weekends—making it Tokyo's most distinctive urban sports and cultural destination.
I. Tokyo Imperial Palace: The Japanese Imperial Residence and Edo Castle Ruins
The historical roots of the Tokyo Imperial Palace trace back to Edo Castle, established by the Tokugawa Shogunate in 1603. This site served as Japan's de facto political center for 265 years. Following the Meiji Restoration in 1868, Emperor Meiji designated the imperial residence in central Tokyo, continuing the spatial logic of the shogunate's political hub.
The Honmaru (main keep) area of Edo Castle now comprises the Imperial Palace East Garden, while the Ninomaru (second bailey) area has been divided into the Imperial Palace Outer Garden and the Marunouchi commercial district. This unique layout—with the imperial residence surrounded by commercial areas—is found nowhere else in the world.
The area surrounding the Imperial Palace has developed a distinctive "imperial-commercial-cultural" three-layer structure: the innermost layer is the imperial family exclusively reserved area, the middle layer features open gardens, and the outer layer encompasses the Marunouchi and Ginza commercial districts. This structure directly influenced Tokyo's concentric urban planning development model.
II. Imperial Palace Outer Garden: The Classic Nijubashi Bridge View
The Imperial Palace Outer Garden covers approximately 10 hectares and is the most famous imperial景观 in central Tokyo, known in English as the Imperial Palace Outer Garden. The highlight of this garden is Nijūbashi (Double Bridge), named for its unique two-level bridge structure rather than the meaning of "double."
Built in 1912 during the reign of Emperor Taisho, the Nijūbashi bridge features a moat approximately 50 meters wide, creating one of Tokyo's most iconic scenes together with the stone walls. This is the classic angle for foreign tourists to photograph imperial architecture, and no reservation is required.
The Imperial Palace Outer Garden is free and open year-round, from sunrise to sunset. The garden features over 200 cherry blossom trees, with the busiest times during the spring cherry blossom season and autumn foliage. The famous "Pine Corridor" walkway spans approximately 1.5 kilometers, with black pines and the East Moat stone walls creating a unique Edo-era landscape.
III. Imperial Palace East Garden: The Only Freely Accessible Part of the Imperial Palace
The Imperial Palace East Garden (Imperial Palace East Garden) is currently the only area of the Imperial Palace open to the public free of charge, covering approximately 20 hectares and located on the former Honmaru site of Edo Castle. Complete Honmaru stone walls, Fuji-no-maru (Fujima Watchtower), and Ranmon Gate (Lotus Pond Gate) ruins from Edo Castle are preserved here.
The Imperial Palace East Garden is completely free, open from 9:00 AM to 5:00 PM (until 5:30 PM from March to October), with Mondays closed regularly (closed on Tuesday if Monday is a national holiday). The garden is also closed from late December to early January for New Year preparations. This opening schedule follows the same seasonal adjustment logic as most Japanese national parks.
The former Honmaru Palace ruins within the East Garden now feature a typical Japanese garden landscape, preserving part of the stone foundations of the Edo Castle tenshu (keep). The garden's "Ukiyo-e Walkway" displays comparisons of Edo Castle scenery from multiple ukiyo-e works by Hokusai—which cannot be seen anywhere else. Visits take approximately 1 to 1.5 hours, making it an ideal midpoint for a Tokyo city walk.
IV. Special Imperial Palace Tours on the Emperor's Birthday: January 2nd and February 23rd Each Year
The Imperial Palace holds two special public openings each year. The largest is the New Year's Income Greeting (Sanngai) on January 2nd, and the Emperor's Birthday (February 23rd) celebration. These two dates are the only opportunities to enter the Inner Palace area throughout the year, attracting visitors from around the world.
The January 2nd Income Greeting is the most important annual event for the Japanese imperial family, with the Emperor and imperial family members greeting visitors from the palace corridors. This tradition began in 1868 and attracts over 100,000 people in line each year.
On the Emperor's Birthday (February 23rd), general Imperial Palace tours are also free, but with daily limits (approximately 10,000 people). Early queuing is recommended. Neither special opening day requires reservations—entry is on a first-come, first-served basis.
Tour routes within the Inner Palace are mainly limited to areas within the Imperial Palace East Garden and Fukiage Garden, with no access to the imperial family's private living quarters. This "limited access" model provides a key window into understanding the relationship between the Japanese imperial family and the public.
V. Marunouchi: The Commercial Heart Next to the Imperial Palace
Located between the Imperial Palace and Tokyo Station, Marunouchi is Tokyo's most central commercial district. The area name originates from the Marunouchi station, and it now serves as the concentration zone for major Japanese corporate headquarters.
Notable buildings in Marunouchi include Mitsubishi Ichigō-kan, a historic red-brick building completed in 1916, now housing dining and business spaces. Other key structures include Marunouchi Oazo and the Tokyo International Forum complex facilities.
The Tokyo International Forum is a representative glass building in Marunouchi, completed in 1997, housing various conference and exhibition venues. Some venues are open to the public, making it ideal for rest and sightseeing during city walks.
Dining costs in Marunouchi are on the higher side, with average lunch prices around JPY 2,000-3,500, making it suitable for high-quality urban lunch options. The atmosphere differs from the youthful vibe of Shibuya or Shinjuku, emphasizing a more urban business feel.
VI. Ginza: Japan'sHighest Land Value Shopping Street
Located south of Marunouchi, Ginza is one of the highest land value commercial districts in Asia. According to Japan's Ministry of Land, Infrastructure, Transport and Tourism's published land prices, Ginza consistently ranks first in Japan at approximately JPY 12-18 million per square meter. This land value level reflects Ginza's core position in Japan's retail industry.
Major department stores in Ginza include Matsuya and Mitsukoshi, both historic Japanese department stores. Matsuya, established in 1925, is known for traditional kimono sales; Mitsukoshi dates back to 1673, making it one of Japan's oldest department stores.
Duty-free shopping services in Ginza are well-developed, with major drugstores and department stores offering tax-free counters. Ginza is not a "激安" (bargain) shopping district, but rather ideal for visitors seeking quality and brand-name items. International luxury brands like Chanel and Cartier all have flagship stores in Ginza.
Ginza's "Pedestrian Paradise" policy is implemented on Sundays and national holidays, with main Ginza streets completely closed to vehicles—the best time for relaxed shopping.
