Not 4 sisters but 2 pairs:
HAMBURG / TOKIO EXPRESS by Blohm+Voss, Hamburg: GT 58.088, 48.750 tdw, 3.010 TEU, 287,61x32,26m, single kingpost aft.
BREMEN / HONGKONG EXPRESS by Bremer Vulkan, Vegesack: GT 57.535, 48.064 tdw, 2.952 TEU, 287,03x32,39m, 2 derricks at bridge front.
Tokio with an i is German spelling like many other languages spell name's places different too.

Perhaps German translation of Tokyo, delivered 12.4.73 as Tokio Express IMO7232822 but ever since Hapag have used Tokyo Express on later vessels. One of a class of four with container capacity of 3,010 TEU on length of 288 meters, these days with design advances similar 300 meter ships can carry 9,000 TEU. Sisters were Hamburg Express, Bremen Express and Hongkong Express and renamed ScanDutch Edo 1985-/85 when charterd by competitors on same Europe/Far East service. Broken up in 2000. Seems to be most famous for losing a container of lego into the sea in 1997. Further info wikipedia:
