That's a real nice condition example of a Japanese navy bomb fuse installed on the nose of aircraft dropped bombs. The model is Type 97 Mark 2 Nose Fuse Model 2 A-3(a) accroding to US ordnance intelligence material.
Here is an extract form the same documents on the operation of the fuse.
"On release of bomb, the arming wire pulls the starting wire through the eyelet. breaking it loose at the soldered points and simultaneously imparting an intial rotation to the arming vane assembly. In seven revolutions, the arming sleeve rises up the striker spindle to lock against the stop screw and arm the fuse. On impact, the entire assembly (vanes, nose cap, sleeve and spindle) are driven inward, shearing the shear wire, and the firing pin pierces the primer"
