W-1 Class: built in 1922-1925. W-4 was built two years after her sisters, and sported an higher fore-funnel.
Only W-4 survived WWII, to be scuttled in 1946 by the Brits at Singapore.
W-5 Class: a slighly modified W-1 class built in 1928-1929. They featured a tripod foremast and different bridge structure. Apparently W-5 had her aft-mast shortened after the Tomozoru incident.
Both were sunk during WWII.
