Help to identify these swords Tokyo national museum

[Paz]

Hi all. I took these pictures in 2014 when I visited the national museum in Tokyo.  Can anyone with a keen eye identity these swords. It was so long ago and I dont have the museum descriptions at all. I only managed to find them as I went through old photos of my trips. 

 

There most likely quite famous.

 

Thanks .

You could try to match them with these pictures from the museum's website:
