An officer in the Japanese army could customise his sword,add a Mon,Old or new made civil mounts. Carry a family blade that may date from the 19th or 13th century.
In this case the officer commissioned both blade and semi military kosherei. The blade,signed 'SadaTsugu' and dated from the war period, also has a Bonji & Dragon horimono.The Bonji is quite apt as it Translates roughly as "KILL THE ENEMY".
All mounts carry on the Dragon theme apart from the Menuki which have the Mon of the Matsudaira which may well have been the officers family or clan. The saya althoughi civil style does not have a kurikata and has the reminants of a Gunto field combat cover.
I am sure most of you will know these facts, for those new to Japanese Military swords.......................
