"Yokohama" is a city in Kanagawa Prefecture, Japan, south of metropolitan Tokyo. It is Japan's second most populated city, after Tokyo, and its most populated independent municipality.
Yokohama appears in Restore Naru's Smile: Usagi's Friendship. One week after Nephrite's death, Usagi and Umino take Naru to Yokohama to cheer her up. They visit a cemetery so they can add a tomb for Nephrite. However, Zoisite also shows up and steals the Orange Crystal from a local priest. The priest turns into Boxy and Usagi transforms into Sailor Moon to fight Boxy. Tuxedo Mask later saves Sailor Moon, and Sailor Jupiter turns Boxy back into a priest. The episode ends at the seaport, with the Yokohama Bay Bridge in the background.
