Another long day here. Finishing work at 5am. Again.
So, a chart for your perusal. I won’t walk you through it this time but leave you to think about it.
The difference here is an important concept.
Every Tokuju item is already something that passed Juyo. Every Kokuho item is already something that was ranked Juyo Bunkazai previously.
In this chart those papers have been plotted at the time of publication of the original sword’s papers.
So going along this chart left to right it goes up in time with all the Juyo. Now say a Juyo in session 10 passed Tokuju later, that item has been colored in as a Tokuju. So basically (this is important that you understand what the chart represents), it’s like someone laid out all of the Juyo swords in order from end to end and plotted them.
Then, you go back and flag the original Juyo as a different color to show it went on to pass Tokuju.
So there are clear trends here which agree to things I’ve routinely said on my sword listings and elsewhere.
