The yard
The story so far
Sumitomo's Oppama shipyard on Tokyo Bay built the hull that became Seawise Giant — delivered in 1979 and then jumboised to 458.45 metres, the longest ship in history, a record that has outlived the yard's own large-ship era.
Sumitomo Heavy Industries has since concentrated on mid-size tankers and machinery, but its name is permanently attached to the upper bound of the length record board.
