Kokyo Gaien National Garden - visitor guide

皇居外苑

Kokyo Gaien's open plaza, black pines and moat-side views frame the outer edge of Tokyo's Imperial Palace. Stone walls, gates and the Nijubashi area help reveal the scale of the former Edo Castle landscape. Explore the public outer grounds as their own walk, keeping palace tours and other separately managed areas distinct from this garden visit.

Why go

The open grounds make the relationship between the modern capital and the former Edo Castle landscape easier to see.

Field Notes

The widely spaced black pines are a maintained landscape with a connection to Tokyo’s former shoreline. This part of the plaza was an inlet of Edo Bay before reclamation for the castle in 1593. Black pines would have grown along that coast; planting of the present grove began in 1888. Their sculptural shapes owe much to continuing pruning and care, so the apparent simplicity of the open ground is carefully produced.

At the famous bridge viewpoint, distinguish the stone bridge in front from the iron bridge behind it. Nijubashi properly refers to the latter. Its name recalls an Edo-period wooden bridge supported by an additional structure below, rather than simply meaning the two bridges now visible. The composition of stone bridge, formal gate and distant Fushimi watchtower is the classic palace view. Knowing those separate elements makes this a more rewarding stop even when the palace buildings themselves remain hidden behind trees.
