the correct way is to have EOD personell examine it.that fuze has no safety clip in it(although it looks like it has had a heavy hit on it already)but it could still be dangerous.it dosent look like the fuze has been out in along time

That is not a Japanese mortar fuze. It is a Japanese artillery fuze that will only function while spinning, so they do not belong together. The mortar fuzes are very hard to find while the artillery fuzes are common. This mismatched combination is more common to find than a properly fuzed round in collector circles.

thank you . so would that make it inert ?

Is it inert? The bomb could be full of impact sensitive, degraded HE, or maybe someone took apart the fuze and now it operates with a simple impact on the nose - no spin required. The risk adverse would tell you to take no chances and hand it over to the bomb squad. What I do know is that it is highly improbable that it was picked up off a battlefield in that configuration. Others would take a calculated risk and use their tools and bench vice to separate the two - the fuze can be sacrificed. However, we are not encouraged to share such techniques in this forum when the inert status of an item is in doubt.
