I concur with what is being said above - upgrade because of your preference, playstyle and how much you like the sword. If you look carefully through the Stats List page for Kiwame Tantous, you will observe that the Kiwames all have their own strengths and weaknesses and are all fairly balanced.

For example, you can have someone like Hirano who has high impact, low leadership and medium mobility, then look at someone like Atsushi, who has medium impact, high leadership and low mobility.

The developers have done a decent job at trying to balance the stats between the Kiwames so that there is no objectively better Kiwame, unless of course, you look only at highest total stats and use that as a benchmark to Kiwame (which a few of my friends are doing because they can't let go of their min-maxing ways).
