An extraordinarily rare Namban tachi mitokoromono. This is a matching set that was made by the same hand and has been together since the day they were made. In the study of Namban items, one hardly ever encounters any fittings other than tsuba. A fuchi kashira alone would be an exciting find as would a tachi tsuba. This mitokoromono reaches the level of once-in-a-lifetime. The theme of this set is dragons chasing the hoju (sacred jewel).
There are many interesting points of appreciation to explore in these. This set is soft metal, made of yamagane, rather than typical iron Namban works. The carving style shows classic Namban style. The gilding is in excellent condition. The seppa-dai of the omote is more round and shaped to accept the round contour of the fuchi. This arrangement is showing a strong foreign influence. The ura seppa-dai is more pointed at the ha end than the traditional Japanese shape. The old style shape may be indicative of the style of koshirae in vogue when this set was made.
This set comes with a large custom fitted box. Please see the photo with a typical tsuba box for scale reference. The box has a lidded compartment on the side and a fitted pillow. The mitokoromono is also accompanied by an NBTHK Hozon paper which states that this set was made for a tachi. There is no small amount of research being done on Namabn fittings nowadays. It is an exciting area of study and this is a set that belongs in the care of a dedicated scholar.
