Signed, ubu, Fukuoka Ichimonji school, Kozon sayagaki. This will be an interesting blade to follow

Just as an example
JuBun Fukuoka-Ichimonji Tachi ubu nagasa 77.1cm and motokasane 0.6 / Sakikasane 0.3
I would take it without a second thought 

Motohaba is also a narrower at 2.65cm.

What a great figure Brano. Did you compile that data? Do you have a similar one for early 14th century Soshuden? 

Here you are
Time span to 1340, Soshu school
Short blades separately and long blades separately

Great data and presentation, thank you for that. Worth noting that because many Soshu smiths had Yamato-den influence (e.g. Go, Norishige, Shizu and their various followers) the data points don't necessarily give a true picture of the actual health of the blades, due to some having significantly high shinogi compared to the mune width.

Same goes for Yukimitsu...
Here are the data reduced for Shintogo, Masamune and Sadamune

Nice work @Brano. Do the dots cross-reference to a specific blade? I'd be curious to know who made the outlier 70cm sword with an 8mm motokasane.

It is this JuBi Masamune

 

However, we must realize that the blade is an o-suriage and we do not know its original length, which was also adapted to the kasane.

Absolutely. Yukimitsu in general is the biggest wildcard among the early Soshu smiths, as he worked in so many styles and sugata (and combinations thereof).
