Fantasy Sword Shop

Now I see some sites call it a katana, others call it a nihonto, others a tsurugi (though i don’t see how when it looks like the Buster Sword From the FFVII series)

Anyone know for sure?? wanted to check the official japanese site, but it keeps saying i need flash (though i have the most recent pluggin installed)

thank you!
I can read japanaese

and the mos useful blurb written on these notes is at the bottom left hand corner reading “Mugen’s sword (the character written is read katana or tou, i think katana is more befitting here) ‘typhoon swirl’ ”
