Edo Castle Project 江戸城特集

The goal of this project is to record all the remnants of Edo Castle that you can see today. It is still a work in progress. I have a few more places to visit and photos to take. The scale of Edo Castle is truly amazing. If you arrived on this page directly without reading the profile of Edo Castle, I encourage you to read that too. This page has more photos than the profile so please view the photos from here. For further details, the photos are also divided by subject and location below. The Google Map is overlayed with an old map from 1803. Use the slider next to the map button in the upper right to change the level of transparency.

Photos by structure type

Castle Buildings

Original and reconstructed castle buildings including gates, yagura, guard houses and more. Some of them can only be see on special occasions.

Stone Walls & Moats

Besides the main inner moats, there are parts of stone walls and moats all over downtown Tokyo, some even further from the castle than you might imagine.

Daimyo Palaces, Temples, Gardens

These are buildings and ruins related to the castle but not strictly part of the castle. There are no more daimyo palaces in Tokyo but there are several gates that have been repurposed around the city.
Photos by location

Imperial Palace Grounds

This is the area currently occupied by the imperial family. You you can only enter a few small areas on certain holidays or by special tour so see everything here.

Imperial Palace East Gardens

The Honmaru, Ninomaru, and Sannomaru baileys are now known as the Imperial Palace East Gardens. This area has most of the extant or reconstructed buildings and gates and some of the biggest stone walls.

Kitanomaru Bailey

Home to the Budokan event hall, this park has 2 gates that are important cultural properties and some great stone walls and moats.

Outer Moat: Hibiya to Toranomon

Hibiya Park and Toranomon areas are where the outer moat starts to spiral away from the castle. Several stone fortifications have been excavated and are on display.

Outer Moat: Akasaka to Ichigaya

This area has several stone wall ruins from the outer moat. Particularly the walls around the Benkei Moat at Akasaka are impressive.

Outer Moat: Iidabashi

The stone walls of the Ushigome Gate of the outer bailey are well preserved here. The nearby Koshikawa Korakuen was also the palace garden for the Mito Tokugawa. Stones from the outer bailey were used to build the outer wall around the garden.

Outer Moat: Hitotsubashi to Otemachi

This is the beginning of the Outer Moat and the point where it is closest to the castle. A large section of the original stone wall still lines the river under the highway.

A note about Maps

I've always loved maps. I could spend hours looking at maps of all types from street maps to topographic maps. Naturally, I've always been interested in maps of old Edo. The map used above is known as the Bunken Edo Map. It is actually compiled from an Edo Period (1803) atlas of Edo. It is one of the most accurate maps made in the Edo Period, which is why I'm using it here (see copyright note below). It's not an exact match to the real Google map but it is fairly close given the time period. I also pinched and stretched the map in some places to help it fit on the Google map a bit better. Click through (coming soon...) to find out more about Edo Period maps.

The thumbnail map images in the section that divides photos by location are from the Mansei O-Edo Map, bought from and used with permission of the Japan Map Center Foundation. I put a lot of work into these pages and the fine people above put a lot of work into digitizing their old maps.
