So putting all this together, we get something about a decision of those two swords being exhibited at that museum, and the pass is 4 numbers having to do with what and when. So we can now probably guess that we just need the date of when that exhibition was decided for. A Google of the original Japanese of "honebamitōshirō to namazuo tōshirō ga Tokugawa bijutsukan" leads us to some links.
http://xn--dkqp0gri91r38rn1wmlurtz.com/archives/61477549.htmlThis is one of the first ones, and it tells us (Google translate it) that
>【For the first time in 400 years】 At the Tokugawa Art Museum, bone meal and Taisuo are displayed at the same time! 2016 8/10 ~ 23So it's either 2016, or it's 0810, or 1008. Probably 0810 since that's specific enough and follows the more normal date formatting. And what do you know, it works. We've cracked it. :)
Hope this has been educational.
