Description
This oval-shaped iron Tsuba has a symmetrical design. It is composed of mainly two motifs: a flower-like object with four petals, and some vegetable or plant pattern arranged in a total of four on the left and right sides of this Tsuba. We estimate this plant is the Myōga (茗荷). It is known as Japanese ginger and was brought to Japan with Shōga (生姜, ginger). According to a theory, Shōga used to be called the Senoka (兄香/せのか), and Myōga used to be called the Menoka (妹香/めのか) in ancient times. It is said that these pronunciations were changed with time. Myōga has the same pronunciation as another word, “Myōga (冥加),” which means divine protection. Therefore, this motif has been treated as a good-luck design. It is seen at shrines and temples in various parts of Japan. Also, it is quite a popular motif for family crests. Such auspicious meanings might have inspired this Tsuba’s design.
