It is likely a "housebrand" from one of the manufacturers there. The same knife is often sold by multiple vendors under different names. If you follow the Japanese knife resellers, you will see the same exact knife except for the "name" and maybe the handle material sold for the same or wildly different prices.
Sometimes though, the knives that come from the same source will see radically different final finishes too where the spine and choil may be rounded or there may be distal taper in one and not the other.
Your pictures are a little rough but, it looks like a pretty common western handled Santoku with San Mai and a white steel core. Personally, I'd clean it up and put it to good use with a poly cutting board.
