I noticed this rare sword on eBay. It was issued to high ranking Chosen (Korea) colonial administration officials, bearing the administrative title of sonnin kan, that is the civilian equivalent to Army superior officiers (major to colonel rank).
It is an interesting sword for the Imperial Japan militaria collector. Like all colonial swords, it looks like a Navy 1883 type dress sword, with the main difference being the side insigns on the backstrap. It bears the 5-7-5 kiri emblem, which was used (among other functions) as a symbol of the Chosen (Korea) colony after the annexation of Korea by Japan.
An interesting feature of this kind of sword is the similiarity between the floral motif on the guard and the one on the 1890 type sword for IJA Navy.
It is also interesting because it is held together by a menuki, whic is rare for this kind of sword. Therefore, it can be taken apart.
The seller is pretending that the blade was hand-forged, which I sincerely doubt since the hamon looks acid-etched.
Anyway, it is a very good piece and the seller obviously does not know what he is selling.
