Interesting Bonji on Naotane Blades

[Bruce Pennington]

@BIG posted this one HERE, but I had one earlier from someplace else.  Just out of curiosity, and like, what else is going on!, could someone break down and translate the 3 sections on these.  There is a curious circled marking on both that is the same, but the other inscriptions are different on the 2 blades.

First one:

Ah, and after taking a second look, I can see that the bonji of both blades seem to be shortened and longer versions of the same thing.  Would still enjoy hearing what they are all saying. 

Thanks in advance to you fine fellows that do this work for us!!!

Hi Bruce, your example is a Daito from a well known Daisho Yamato den. There are rising dragons on the blade with bonji over the dragons.

So, is that this part of the bonji:?

 

If so, what is the circled inscription saying?

The writing in the bit that seems a bit recessed inside the tang is an invocation of a buddhist god (well, buddhist by way of hinduism).

I have reservations on this one, mei is different from good Naotane I have seen.

Hello Tom, this is a Jūyō sword, authenticated at the 60th Jūyō Tōken appraisal. I think the mei is as good as it gets.

Thank you for making that clear.  The one I compared it to, may have also made juyo. It mentioned in large strokes, if I remember ( in 1974) correctly, something,something '5000 years ------------ ------- ------ etc. A Japanese nihonto dealer bought it. It may be listed as a juyo?
