Much larger numbers of troops of the 20th (East Devonshire) Regiment of the Foot arrived on troopship HMS Vulcan in January 1864, together with two companies of the 2nd Baloochees from the Bombay Native Infantry.

Contemporary maps produced in 1864 indicate that officer and troop accommodation, a naval hospital, stores facilities and a large parade ground stretched from the modern park area overlooking the harbour as far as the current location of Christ Church, Yokohama.

Detailed Royal Navy medical records of the period reported frequent smallpox outbreaks among the troops and that a dysentery epidemic shortly after the arrival of the Marine Battalion in the summer of 1864 claimed the lives of 11 men.

Although many of the original foreign resident's accommodation and civic buildings were destroyed in the Great Kantō earthquake, a number of older Meiji and Taishō Period properties have been preserved and relocated to this neighbourhood.

The buildings and their ornamental gardens are open to the public free of charge and serve as popular tourist attractions, many featuring tea rooms, art and seasonal ikebana exhibits.

Ishikawacho Station on the JR East Negishi Line provides alternative pedestrian access to sites such as the Italian Garden Park, Bluff 18 House and Ferris University.
