Hama-Rikyu Gardens: Originally a residence of the Matsudaira feudal lords during the Edo period, this garden later gained historical significance when it was transferred to the Imperial family. It is larger compared to Kyu-Shiba-Rikyu Garden and features expansive tidal ponds, historical teahouses, and traditional landscaping that integrates with Tokyo Bay. It is a 15-minute walk from Kyu-Shiba-Rikyu Garden and the entrance fee is 300 yen.
