The first group, or "Fubuki" class, consisting of the first ten vessels completed in 1928 and 1929, were simpler in construction than the vessels that followed. They had a rangefinder on the compass bridge and an exposed gun-fire control room, and were equipped with a “Type A” gun turret that elevated both of its barrels at the same time and only to 40 degrees. The first group can be distinguished from later ships by their massive circular air ducts abreast the two stacks leading to the boiler room, with the exception of , which integrated the ventilation ducts into the platforms built around the stacks.
