Matsu-no-Oroka — the corridor inside Edo Castle where the 47 Ronin incident began — is now part of the Imperial Palace East Gardens. This guide covers the site, Fujimi-yagura turret, and what survives from the original castle.

The Ninomaru Area holds one of the East Gardens' best-preserved historic gates, a traditional teahouse, and a landscaped garden — less visited than the Honmaru, but worth the extra few minutes.
