Unknown Rifle from Japan? WWII?

My friend's grandfather gave him this rifle - Grandfather was in the U.S. Navy and stationed in Japan at the end of WWII. He got the rifle as a war souvenir - We think it is missing the firing pin and who knows what else. Cant figure how to get the bolt out, only markings found are on the butt plate and the stamp "1961" with the Led Zep symbol after:) Any ideas?

WWII Japanese Type 99 Arisaka.


The bolt release it the spring loaded lever device on the left rear of the receiver. Pull out on the front of it and the bolt will pull straight out the rear.


Don't know what to tell you about the name on the butt unless that is your grandfather.
Certainly nothing the Japanese put on there.

Thanks! Looks like it was a later batch of rifles from the Toyo Kogyo area. Thanks for links- it also had the imperial mark of the Emperor ground off. Pretty neat peace of history.

That little lever on the left of the receiver is the bolt release.

The safety is missing and more than likely the firing pin and spring are, too, probably done to deactivate the rifle for safety or legal reasons. It is a late rifle, judging by the wooden buttplate, but still has the oval bolt handle.

Yeah, from the oriental squiggles decoded on the above link, it is of the 34th series... and they only got to 35. Not a last ditch rifle by a long shot but not one built while they were winning.

I agree, the whole bolt sleeve assembly is out. Probably to keep the kids from shooting out the street lights.

You have a mid-war production Arisaka 99. I can tell it is mid-war by the absence of a hole near the stock crosspiece and the removal of the antiaircraft calipers, but otherwise high quality. It is missing the following parts:

Bolt back, striker, and striker spring.

You can likely source the parts for under $100 and restore it to operation. My grandfather brought back an early-production Arisaka from Okinawa in an identically-disabled condition. I ordered the parts and had the pleasure of shooting a rifle that was untouched since World War II.

That Arisaka certainly is missing the safety device and spring.

Normally, a complete bolt on an Arisaka is removed by opening the bolt and simply pulling that lever on the left side of the rifle. After which, the bolt should slide out easily.

If pulling out the bolt-catch lever on the left side of the gun does not allow the bolt to come free, then the firing pin may still inside of the bolt, in which case the release notch for the firing pin assembly is likely protruding against the bolt catch. The firing pin is part of a large assembly. If you can't look through the bolt and see light through the hole for the firing pin on the other end, it's probably still in there.

A friend of mine had had an Arisaka in similar condition, and the firing pin was the culprit. The safety mechanism on the back-side of an Arisaka bolt also keeps the release notch for the firing pin in place. When the safety and bolt spring are removed, the firing pin assembly will rotate with the bolt and the firing pin release notch will rotate with it and protrude against the bolt-release lever. This of course prevents the bolt from being removed.

I was able to remove the bolt by unscrewing the flat-headed screw on the top of the bolt catch. This screw is visible in your top-down picture of the receiver. After removing the screw, I was able to free up enough clearance to slide the bolt out.

Later, I discovered a trick to rotate the firing pin assembly inside of the bolt that allowed it to clear the bolt catch.

Now before attempting any gunsmithing with you gun, please remember to be gentle with it. My friend in question played a little too roughly with his and managed to break its stock before I even had a chance to look at it.

If you’re thinking about restoring this rifle, I would check the top of the receiver first. The picture you provided of the top of the receiver on this gun ends just short of the money-making part. Factory-original Arisakas were typically stamped with a chrysanthemum flower on top of the receiver. Most imported Arisakas had this symbol ground-off by the US government, as it was an imperialist Japanese symbol. Imported German weapons with Nazi symbols were treated in the same fashion.

If your gun still has it's prized flower, then buying a new bolt is a no-brainer. If it has been "deflowered", it will still make a nice shooter, but remember that ammo isn't cheap for these guns anymore.

The bolt back is also the (effectively unusable) safety. I reassembled mine after I got the parts by placing the bolt head on carpet and leaning into it while turning the bolt back to lock it into place. If you restore yours, and I strongly recommend you do (they're nice shooters), you'll quickly realize the safety is useless, and it's far easier to just open the bolt than to mess with the "safety'.

Mike, I have to think you were doing something wrong. The Arisaka bolt is the easiest to dis- and re-assemble of any rifle bolt, ever, plus it has only six parts, vs. 9 for the Mauser 98. While some late ones can be rough, the safety is normally easy to apply and remove with thumb pressure and is not only faster than any others, but doesn't require taking the hand from the firing grip.

Hornady manufactures 7.7x58 Jap ammo on PRVI Partisan brass. The brass is headstamped PPU, just like my PRVI-branded 7.62x54R.

As for my Arisaka's safety, keep in mind that it I had to replace the striker spring too. The spring I got is very strong. It effectively renders the safety unusable.

Jims right: make sure the striker is down in slot and it will assm easy. I have seven.G parts does not have striker or safty.
there is a dealer in Japs that is in NC
