Special feature:Matsumura Masanao was a Samurai of a feudal lord of Higo Kumamoto.
He studied under the master Masayuki, and Suishinshi Masahide, 10th generation
Tsunehiro and also he was well known sword judge.
The reason why he mad few swords during his life is that he helped his master
Masayuki. Or his sword and Okachiyama Nagatada was changed to old famous sword
by removing the signature and cut shortened the blade.
This sword is mentioned exactly same sword at Shinshinto Taikan.Page524 rhwe book
says that the blade is the blade is healthy and good work and looks Masayuki. also
another Masanao passed Jyuyo token.
The reason why he was studying Masayuki and Motohira is that the Nakago line reached
a little aside of the bottom line. This mark is a major feature of Motohira and Masayuki,
and was made to prevent counterfeiting.
If this hidden mark is still valid and there is no such mark at first glance, it is judged as a
fake. Matsumura Masao is also same.

From Aoi Art: any of Matsumura Masanao's works are well-made. It can be said that it
is an extremely rare item. The reason why Matsumura Masanao is
designated in the 33rd Jyuyo Token sword is that it seems that the work
is exactly the same as Motohira and Masayuki. This work is posted on
page 524 of the New New Sword Encyclopedia,page 524 (新新刀大鑑)

on Scabbard. There are no materials such as writing papers, so
