Kokyo Gaien National Garden is the Imperial Palace’s public outer garden at 1-1 Kokyogaien, Chiyoda City, Tokyo 100-0002, between the palace moats and Marunouchi. Opened to the public as a national garden in 1949, this former forecourt of Edo Castle draws visitors for black-pine lawns, monumental gates, and the classic Nijubashi bridge view. Come for the spacious landscape and castle history rather than flowerbeds or access to the emperor’s residence.
What to Expect at Kokyo Gaien National Garden
The main plaza combines broad gravel surfaces, clipped lawns, and roughly 2,000 Japanese black pines. Beyond the moat, massive stone ramparts recall the Tokugawa shoguns’ Edo Castle; the imperial residence moved here after the Meiji Restoration. At the southwest palace entrance, distinguish the foreground stone bridge, Seimon Ishibashi, from the iron bridge behind it, Seimon Tetsubashi. The latter is technically Nijubashi, although the name commonly describes the entire view. Ordinary garden access does not include crossing these bridges into the palace.
Walk southeast to the bronze equestrian statue of Kusunoki Masashige, the fourteenth-century warrior celebrated for his loyalty to Emperor Go-Daigo. Unveiled in 1900, it stands near the Nanko Rest House, a practical refreshment and souvenir stop. Northeast, Wadakura Fountain Park introduces a different design language: water jets, geometric pools, and stone terraces framed by Marunouchi’s office towers. Its fountains originated in 1961 to commemorate Crown Prince Akihito’s marriage and were reconstructed in 1995 for the next crown prince’s marriage.
- Nijubashi viewpoint: Photograph the stone bridge, moat reflections, and palace-side Fushimi turret from the public forecourt.
- Black-pine landscape: Follow the lawn edges to appreciate carefully maintained trees against the castle’s stone defenses.
- Kusunoki Masashige statue: Examine the charging horse and armored rider, one of Tokyo’s prominent Meiji-era monuments.
- Sakuradamon: Explore the imposing surviving castle gateway associated with the 1860 assassination of chief minister Ii Naosuke.
- Wadakura Fountain Park: Add water features and a rest stop to the northern end of your walk.

Visiting Tips, Getting There & Nearby Pairings
Arrive early for softer light and quieter bridge photographs; summer afternoons can be hot across the exposed plaza. No garden reservation is needed, but palace tours and the Imperial Palace East Gardens have separate arrangements. Seasonal guided walks are advertised on the official website. Tokyo Station’s Marunouchi side and JR Yurakucho Station are approximately ten minutes away; Sakuradamon Station on the Yurakucho Line is about eight minutes from exit 3. Drivers should use commercial Marunouchi garages rather than the Nanko bus parking area.
The broad, mostly level outdoor routes suit strollers and wheelchairs, but deep gravel can make self-propelling difficult; favor paved perimeter paths. Use station elevators rather than assuming the nearest numbered exit is step-free. Rest at Nanko Rest House or Wadakura’s rest facility, and consult the official map for toilets. Hibiya Park is roughly 5–10 minutes south, Marunouchi Naka-dori’s dining and shopping street about 5–10 minutes east, and Tokyo Station’s restored red-brick frontage about 10–15 minutes east. Keep dogs leashed and respect fenced lawns.
Frequently Asked Questions
When is the garden open, and when should I visit?
The public outer grounds are generally accessible daily, including Sundays, rather than following office hours. Visit in daylight for the architecture; security measures and imperial events can restrict access.
Is admission free, and can I buy food?
Admission is free, with no timed ticket required. The official bento offering includes a ¥2,280 tax-inclusive Shokado box with salmon, chicken rolls, and rice; check ordering arrangements before planning around it.
How long should I allow?
Allow 60–90 minutes for Nijubashi views, the statue, and Wadakura. Budget additional time for the East Gardens, which are a separate destination.
Is it suitable for families and wheelchair users?
Yes, with mostly level routes and ample outdoor space. Gravel, long exposed stretches, and limited shade warrant a deliberate route and regular breaks; no religious dress code applies.
