Cool documentary thank you for sharing!

To the best of my knowledge there were 3 different lengths specifications: 2.0 to 2.1 shaku 2.1 to 2.2 shaku 2.2 to 2.3 shaku To accomodate soldiers of different heights Nakago lengjth spec was 212 mm.

They are what they are there is no questioning that. But the facts are we really dont know all the facts. In response to ro your commentary : We all want to know more and it is a study in progress.No need to belittle what you personally do not like. But that is your decision.Let us all strive together for the good of all involved. The more we know the better off we all are.

Looks like 1880's from Suya Shoten type 19? The experts can tell you more....

Each of the Dojos in 1946 were 200ft long and 40 ft. Wide times 7 total equals 56000 square feet of floor space for cadet training .they must have had a large surplus of swords there at wars end that were not used in combat making them eligible for satisfying U.S. requirements for purchase as souvenir swords .

Toyama Ryu had 6 Dojos for sword trainng and 1 for bayonet training if my notes are correct. Still researching...

Definitely Takayama Masakiichi being a 10th Dan in Kendo,had alarge influence in Naval cadet training and later in war also for the Army training in Toyama.He Instucted Seki area swordsmith on how to build a killer blade in essense and practicality.He was one bad dude .

Tenshozan Tanrenjo produced 8747 swords in 436 days ending in March 1947 that means they produced 20.06 swords a day .Since they had 20 fitting rooms that would mean 1 sword per day per toshigi.

Tomita Electric Company if I am correct ?

On page3 of Who was Toyosuke ?which is now on page17 of the military swords you will find some of your answers they were graciously provided by Kiipu ,Bruce Pennington And others ..very informative.

Once more I am going out on a limb on this commentary : I beleive that Toyosuke was the name used to designate swords for Toyama Ryu ,and Takeyasu name was used to designate swords for Takayama Ryu for Batto jutso training.And were likely made by the same swordsmith filemarks and other characteristics being the same suchas green paint,black paint,4mm naval acceptance stamp,hot cut nakagos...

It is my belief that the souvenir blades were originally 2nd design Takayama- to's with long nakagos intended for Takayama Ryu and or Toyoma Ryu for training cadets .Being surplus were collected by Zenhiro Hattori with the help of his Son in law Eiji ,then hot cut to fit standard RJT length koshirai at the Tenshozan Tanrenjo

Hey JohnC ,to answer your question the nakagos of the Takayama-to was about 1 shaku or 303mm The Rinji seishiki 242 mm the R.J.T. nakago spec.was 217 mm the souvenir swords 226mm,1940 naval spec was 206mm std kosherai. If my notes are correct. Itrust all is well with you and yours. John Stroud The measurement for the takayama to is an approximate measure as I have yet to physically measure one .Using length to width ratio to calculate from photos.

The records of the army documents contract name "The Japanese Naval Sword Company " aka Tenshozan Tanrenjo .I suppose the swords would have to have at least a element of Naval characteristics to satisfy the army contract .Along with " premise " that the blades were not used in combat as a condition of the contract.
