Certified tosogu register?

[Spartancrest]

I was just wondering if anyone knows if there is register of  NBTHK certificate numbers? Also are duplicate certificates kept as references by NBTHK?

It would be a great resource for study if available.

Hello Dale,

 

The NBTHK main office at the Japanese Sword Museum in Tokyo, Japan (The Japanese Sword Museum (touken.or.jp)) has a registry of the NBTHK certificate numbers. What information is recorded in the registry and how helpful it would be to study I am not sure because I only had limited use of it myself over the years. I have been a member of the NBTHK since 2007.

Thanks David, I was just wondering if I quoted a certificate number as a reference to a particular type or design of guard, if that could be used as an example people could look up, but if there is no general access to images on the certificates then the certificate number would not be of much help. I will have to find other examples from museums where stored images can be found by the general public. - it was a good idea that didn't work out.

Dale - 

The closest thing to a collection like the one you suggest is the Juyo To-ken Nado Zufu - if you had these you could then pull out and collate all the Juyo Tosogu and you would have a mightly powerful reference. I am sure there are collectors who have done this - I know it has been done for swords...

I think if you have specific design in mind you could message forum member MauroP, I've seen him having nice collection of saved items for research purposes as he has posted interesting examples on this board.

 

If you have the design or type in Japanese you can try typing it into the Jūyō index I compiled. Unfortunately I didn't feel qualified to translate them in English but I did type in all of the kanji in fitting designs that was featured in item header.
